Design of earth structure with optimum approach

In the construction work of earth structure, the troubles occurred sometime as follows,
  • 1) Slope failure by embankment
  • 2) Long-term settlement
  • 3) Failure of earth retaining
  • 4) Incline and/or deformation of substructure and retaining wall
  • 5) Liquefaction due to earthquake
  • 6) Adjacent ground deformation and etc.
We are applying numerical analysis on these practical problems. We will continue to approach to a more secure and economical design. Because we know the site very well, we can offer the optimal design.

Construction of tunnels in
deep subterranean

The tunnels, deep shaft and connection tunnels were constructed deep underground. These tunnels were located complex arrangement.
3D-FEM analysis, which was reproduce the construction process faithfully, was carried out for predict ground deformation due to tunnel excavation.

Ground deformation due to excavation

Deformation due to
embankment on soft ground

It was concerned about adverse effect on adjacent structure by ground deformation due to embankment on soft ground. 3D-FEM was carried out to determine the arrangement of stabilized bodies to prevent ground deformation efficiently. The result was reflected in the practical design.

Ground liquefaction by
Earthquake

Liquefaction might cause a serious damage to the embankment, pier and abutment, retaining wall, architectural building and etc. 3D-FEM simulation of liquefaction could use for prediction of its damage and selection of optimum countermeasure.

Some examples of
earth structure

In order to construct embankments, tunnels and etc. safely, appropriate countermeasure might be required as necessary. We can support the design of structures such as a box culvert, bridge abutment and etc. from the geotechnical point of view.

Construction management

In order to reduce the cost of construction projects, the design phase check will be most efficient. Check the design of course, we will support the client technically from soil investigation to construction stage or all construction process as an in-house engineer.

Support for value engineering

We will pursue the economic design while ensuring safety and reliability of construction method. Since we are familiar with the construction work, we can offer the flexible and realistic proposal for value engineering. We will contribute as a few pearls of wisdom of construction company.
