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.

Figures 1–3 also show locations of selected soil elements where stress paths from the numerical simulations are examined in details. These locations are designated from S-1 to S-9 and are taken within the fill, soft clay, and medium clay layers. 3. EXTENSION OF SELFSIM TO THREE-DIMENSIONAL EXCAVATION ANALYSIS 3.1.

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.
