Abstract

To ensure the dry conditions of the construction site, several measures were adopted to lower the groundwater level. But it should bring negative effects to the

surrounding constructions, such as consolidation subsidence. Taking Jinzhou-Pulandian line 8th section of underground tunnel precipitation engineering as an example, the hree-dimensional differential numerical simulation software FLAC3D was used to establish the coupled model of seepage and stress field during dewatering process. The objective of this study is to explore soil subsidence and distribution of groundwater with the change of permeability coefficient under the condition of saturation.

Key words： engineering precipitation; permeablility coefficient; consolidation subsidence; FLAC^3D; fluid-solid coupling
