A numerical interpretation of the soil-pile interaction

The response of the pile is closely related to the soil-pile interaction caused by excavations. In this analysis, three cases representing different excavation processes (i.e. 1-step implementation, 4-step implementation, and 8-step implementation) for the 4 m deep excavation are denoted as Excavation_1, Excavation_4, and Excavation_8

Dec 09, 2014 · As is well-known, a progressive failure may be triggered in these soils by excavation and it can cause the collapse of the slope after some time. The numerical approach used in the present study allows this phenomenon to be properly simulated. Results from both two-dimensional (2D) and three-dimensional (3D) analyses of the landslide are performed.

Three‐dimensional inverse analyses of a deep excavation in

Aug 24, 2010 · Numerical models are commonly used to estimate excavation-induced ground movements. Two-dimensional (2D) plain strain assumption is typically used for the simulation of deep excavations which might not be suitable for excavations where three-dimensional (3D) effects dominate the ground response.

Numerical Simulation Study on Three-Dimensional Seepage

This article describes the pumping test procedures and test results of the subway project 30m deep excavation dewatering in thick aquifer. A groundwater three-dimensional seepage numerical calculation model is established. We use the model to calculate and compare the calculated results and the actual results, obtain hydrogeological parameters by inversion.
