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.

Three-dimensional inverse analyses of a deep excavation in

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.

3D numerical analysis of pile response due to soil

Jul 05, 2021 · Using the explicit finite element code PLAXIS 3 D, a full three-dimensional numerical analysis is carried out to investigate pile responses when performing an adjacent deep braced excavation. The numerical model was validated based on the results of a centrifuge test. The relevance of the 3 D model is also judged by comparison with the 2 D
