摘要
以某重力式挡土墙为工程实例,首先采用理正岩土计算分析软件对其稳定性、地基承载力、截面应力进行验算,其次采用ANSYS有限元分析软件,基于其平面应变建立精细化分析模型,最后在考虑土体与重力式挡土墙表面摩擦的基础上,利用接触单元进行分析。研究结果表明:重力式挡土墙的稳定性、地基承载力、截面应力满足结构受力要求,其结构变形较小,尚有足够的主拉应力储备;墙前填土较高且容易遭受破坏,建议设置防滑凸榫或增大墙底倾斜坡度。
Taking a gravity retaining wall as an engineering example,an initial checking calculation has been made of the stability,foundation bearing capacity and section stress of the retaining wall by adopting the normalized geotechnical calculation and analysis software.Secondly,ANSYS finite element analysis software is used to establish a refined analysis model based on its plane strain.Finally,the contact element is used for an analysis with the surface friction between the soil mass and the retaining wall taken into consideration.The results show that the stability,foundation bearing capacity and section stress of the gravity retaining wall meet requirements of the structural stress,with its small structural deformation making enough principal tensile stress reserve possible.Given the vulnerability of the high wall filling to damage,it is highly recommended that the anti-skid tenons set up or the slope of the wall bottom be increased.
