Soil Movement & Stability Solutions

Today we rely on a network of tunnels, pipelines and underground structures for everything from power supply to transport. The performance of these tunnels depends on their material and structural integrity and their ability to resist external forces.

The design of deep excavations and tunnels in crowded cities is a technical challenge for engineers. In these environments, engineers often need to look at the effects both below and above the ground (loading the ground and excavation). Our range of soil movement and stability software provides the tools needed to do this quickly and effectively.

To estimate the effect on surrounding structures, most urban tunnelling or excavation work requires ground movement as well as building and utility damage assessment. But producing them with different analysis programs and spreadsheets can be time-consuming and difficult to check. Xdisp is the industry standard, analysing and displaying the results in clear 3D graphics.

Pdisp offers a quick and accurate way to predict soil displacement due to load. The program predicts displacements in a soil mass due to vertical and horizontal loads, showing the settlement beneath and beyond the loaded area.

Slope provides a robust way to study a slip surface to find factors of safety against failure, and to check the improvements from reinforcement. The software performs two-dimensional slope stability analysis to a variety of methods and presents the results in a clear graphical format.

Whether engineers need to do two-dimensional finite element computations in plane stress, plane strain, or axial symmetry, Safe takes care of it. The software identifies pore pressures and effective stresses over the construction period from gravitational loads, initial stresses, excavations and ground water movements.
