Services
Our Expertise
We provide suitable design analysis for all types of geotechnical problems in soil and rock. Our expertise and knowledge in designing geotechnical surface and underground structures and determining their ground stresses , movements , settlements and displacements through numerical analysis and through sophisticated specialist software packages, enable us to conduct analysis of complex geotechnical schemes and able to maximize the efficiency and effectiveness of the adopted design solutions.
Services for Different Design Stages
We provide reliable and cost effective geotechnical & Structural designs to our Hydropower Clients. We help our clients in the following design stages of Hydropower Projects:-
- Alternative Studies
- Preliminary Design
- Geotechnical Report
- Tender Stage
- Tender Evaluation
- Detail Design Stage
- Design Review
- Others
Structural Elements Design
We provide designs of structural elements used for stabilizing the excavation in soils as well as in rock. The structural elements are as follows.
- Rock Dowels & Soil Nails
- Rock Anchors & Cable anchors
- Steel Ribs and Lattice girders in Tunnels & Shafts
- Shotcrete and SFRS
- Wire Mesh
- Concrete lining for tunnels and shafts
- Sheet-pile Wall Analysis anchored with grouted tiebacks
- Others as per design requirement
Slope Stability
We provide the slope stability analysis both in limit equilibrium and FEM. We design excavated slopes along with its stress analysis, Check their stability, groundwater analysis and also provide designs of excavation support system both in soil or rock. In our designs we perform seismic analysis for slopes. For embankments and dam abutments where there is fluctuation of water levels. We adopt the following conditions for analysis and check their stability and seepage effects:
1. Empty 2. Full water level
3. Minimum water level 4. Sudden draw down of water levels 5. Above conditions with Seismicity.
Underground Excavation
By using FEM software, we design complex, multi-stage models and interprets results for every stage of excavation. We design tunnels and shafts in weak and jointed rock, underground power house caverns and tunnels portals. We adopt all rock mass classifications for determining support measures empirically and numerically for all tunnel classes. Numerically We adopt convergence-confinement method for anticipating deformation in rock mass and support design.
Here we adopt longitudinal displacement profile (LDP) to relate tunnel wall deformations at successive stages in the analysis to the actual physical location along the tunnel axis. We also provide empirical designs.
Tunnel Lining Design
Tunnel Lining is designed for both hydropower and transportation tunnels and design for both internal as well as external water pressures, wedges and other existing pressures.
Deep Excavation
Shoring Design for deep excavation for the construction of building basements. Determine the type of piles used for excavation as per geology of the site.
- Sheet piles
- Contiguous piles
- Soldier piles
- Strut Design
Seepage and Groundwater Modelling
We perform analysis to assess potential groundwater inflows during construction and the potential water level changes and settlement due to draw down beneath surrounding properties.
