地下水恢复期共同抗浮作用下底板变形分析
Analysis on the Deformation of the Bottom Plate under the Joint Anti-Floating Action in the Groundwater Recovery Period
摘要
Abstract
The construction of the deeply-buried underground structure may disturb the natural groundwater,which may cause uplift damage to the underground structure under the change of water level.With the increasing depth of the underground structure,the groundwater is rich,and during the construction process,the enclosure and the underground structure participate in the anti-floating work.Based on the deeply-buried underground structure,the paper studies the influence of the underground diaphragm wall on the deformation and force of the bottom plate in the process of water level recovery during the construction and operation of the underground structure.The study shows that changing the depth of the underground diaphragm wall will change the stress and deformation of the base soil,increase the stress of the base soil at the age,and reduce the deformation of the base soil at the junction.Increasing the depth of the underground diaphragm wall will reduce the deformation of the bottom plate at the edge,increase the uneven deformation value,and increase the bending moment and shear of the bottom plate at the edge.Considering the economic factors,choosing the underground diaphragm wall with a 53 m depth can effectively control the deformation of the bottom plate.关键词
