Numerical simulation of the influence of ground fissures on the deformation characteristics of the surface

IOP Conference Series: Earth and Environmental Science, 2021
Abstract in order to study the influence of ground fissures on the construction of expressway, a ground fissure (F1) with a strike of NE20∼45° and length of 120km in Yunnan Province is selected as the research object. The FLAC3D numerical software is used to study the characteristics of displacement and stress. The results show that: (1)
