GEO5 Solutions - Detailed
Stability Analysis
- The basic program for stability analysis is Slope Stability. It enables design and analysis of slope stability with circular or polygonal surface and automatic optimization of slip surface. It cooperates with all programs for analysis of Excavation Designs and Retaining Wall Designs. It enables creation of anchors, georeinforcements, surcharge and earthquake effects modeling.
- The program for analysis of MSE Walls reinforced by georeinforcements is MSE Wall, which contains a large database of georeinforcements of different production firms. The program for nailed slope analysis (passive nails with shotcrete face or steel mesh) is called Nailed Slope.
- The Rock Stability program is designated for analysis of rock slope stability for a specified type of failure, including a planar or polygonal slip surface or rock wedge.
- The Anti-Slide Pile program is used for design of pile walls stabilizing slope movement or increasing safety factor of the slope.
- All stability problems can also be solved by finite element method (fi,c reduction method) in the FEM program.
The ground water table can be calculated in the FEM – Water Flow program, and then passed into Slope Stability
or FEM programs for stability analysis.
Excavation Design
- The GEO5 Sheeting Check program is used to make advanced design of anchored or strutted retaining walls (Sheet pile, Diaphragm, Pile or Soldier pile walls). It allows the user to model the real structure behavior using stages of construction, to calculate the deformation and pressures acting upon the structure, to verify the internal anchor stability or to verify steel, RC, vinyl or timber cross-sections and the bearing capacity of the anchors.
- The GEO5 Sheeting Design program is used to perform a quick design of non-anchored structures or a basic design of anchored structures. The program calculates the required length of the structure in soil, the internal forces on the structure and verifies cross-sections (RC, steel, vinyl, timber).
- Both programs support design of variety embedded retaining wall types (Sheet pile wall, Diaphragm wall, Soldier pile wall and Pile wall).
- Also both programs allow analyzing overall stability using the GEO5 Slope Stability program.
- Program GEO5 Shaft is designed for calculations of load and stress of circular, vertical shafts.
Walls and Gabions
- Overall stability analysis of all retaining wall types can be performed directly with the Slope Stability program, foundation can be analyzed using the Spread Footing or Pile programs.
- The MSE Wall program is used to analyze segmental retaining walls reinforced by georeinforcements. It contains a large database of georeinforcements of different production firms. The program for nailed slope analysis (passive nails with shotcrete face or steel mesh) is called Nailed Slope.
- Program Abutment is designated to verify bridge abutments including wingwalls and construction stages. Additional program Earth Pressures allows to verify the earth pressure load on a general structure.
Shallow Foundations
- The GEO5 Spread Footing program is used for isolated footing and strip footing design (including spread footing with haunch bearing capacity). It enables verification of bearing capacity of a foundation on both, drained and undrained soil and rock subsoil. The program also calculates the settlement and rotation of the foundation and allows designing reinforcement for the foundation.
- Program GEO5 Slab is designated for analysis of foundation mats and slabs on elastic subsoil. The program uses the Winkler-Pasternak model and is able to calculate C1 and C2 constants from deformation properties of soil – piles can be model as springs.
- Internal forces and deformations of strip foundation can be calculated by program GEO5 Beam. Program allows
to calculate values of C1, C2 from input soil profile. - It is also possible to verify some problems (eg. circular force) using the finite element method in the GEO5 FEM program using axisymetry.
Deep Foundations
- The Pile program is designed to verify vertical bearing capacity of a compressive and tensile pile, pile settlement and horizontal bearing capacity of a single pile. It is also possible to design and verify a reinforcement of different types of piles, which can be divided according to pilling method as driven, bored or CFA piles.
- The Pile CPT program is designated to verify bearing capacity and settlement according to results of a cone penetration tests (CPTs) or standard penetration tests (SPTs).
- The Pile Group program is designated to verify pile group with rigid foundation mat, using the spring method (FEM) or analytical solution.
- The Micropile program verifies tube micropiles (made from steel tube). When analyzing the bearing capacity
of the micropile, the root part and cross section of the micropile are verified. - Some problems (eg. single pile) can also be solved by the finite element method in the FEM program using axisymetry.
Settlement Analysis
- The Settlement program is designated for analysis of terrain settlement from surcharge or under constructed embankment. It also enables calculation of consolidation using analytical method (Terzhagi).
- It is also possible to analyze settlement using the finite element method in the FEM program. FEM – Consolidation module then allows calculation of settlement in time.
- Settlement and rotation of a shallow foundation is analyzed in the Spread Footing program.
- It is possible to calculate settlement or load-settlement curve of piles in the Pile, Pile CPT and Pile Group programs.
- The Ground Loss program is designated for analysis of terrain settlement and risks of building damage above
a constructed tunnel.
Tunnels and Shafts
- Tunnels are modeled using the finite element method in the FEM program. The FEM – Tunnel extension module also contains these functions:
- creation of a geometrical model of the lining in a separate pre-processor
- Use of a relaxation factor to model the 3D behavior of the body during excavation
- Input of temperature loads
- Consideration of soil swelling
- Consideration of lining shrinkage
- The Ground Loss program is designated for analysis of terrain settlement and risks of building damage above a constructed tunnel.
- Program Shaft is designed for calculations of load and stress of circular, vertical shafts.
Geological Survey
- Stratigraphy is designed for engineering geologists, hydrogeologists, and also for geotechnical engineers and companies providing the geotechnical investigation services. The program enables the creation of borehole logs and reports of various field tests types and the easy construction of geological cross-sections, fences and soil profiles. All data is interconnected in the program and 3D geological model can be created - this becomes the basis for next work of the geotechnical engineer. Resulting data can be directly exported to the GEO5 design programs.
- Stratigraphy - Logs module is designed to produce geological data reports from site investigations (boreholes, wells, SPT, CPT, DMT and more). It provides a comprehensive database of pre-defined templates and the ability to create user-defined templates and data reports.
- Stratigraphy - Cross Sections module creates easily geological cross-sections without any need for additional CAD programs. Geological interpretation can be done by input of interfaces between layers, faults and connecting of boreholes into the model. Groundwater levels, structures and user descriptions can be added into the cross section drawing.
- Stratigraphy - Earthworks module is designed for modelling structures, such as foundation pits, roads, railways, quarries, slopes, and others. It also provides calculation of earthwork or terrain movement volumes. Cross sections, which can be exported into other GEO5 programs can also be created.
Field Tests
- The Pile CPT program is designated to verify bearing capacity and settlement according to results of a cone penetration tests (CPTs) or standard penetration tests (SPTs).
- The Spread Footing CPT program analyzes bearing capacity and settlement of spread foundation according to cone penetration test (CPT), standard penetration test (SPT) and flat dilatometer test (DMT) .
- The Spread Footing program analyzes settlement of spread foundation according to flat dilatometer test (DMT).
- Program Micropile calculates the modulus of subsoil reaction according to pressuremeter test (PMT) and standard penetration test (SPT).
