本文基于土体本构模型理论,将考虑上下负荷面弹塑性本构模型引入到地基土承载力验算中,通过有限元软件,有效分析地震荷载作用下地基沉降,对结构设计有重要指导意义。本文首先以某污水处理厂储泥池设计为例,对其地基承载力不足问题,在有限元计算软件中建模分析计算,得出砂土置换后地基土沉降特性,加载地震荷载,计算其在地震荷载作用下的不同土质的最终沉降问题。
Based on the theory of soil constitutive model, this paper introduces the elasto-plastic constitutive model considering the up-and-down load plane into the checking of the bearing capacity of the foundation soil. The finite element software can effectively analyze the settlement of the foundation under the earthquake load, which has important guiding significance for the structural design. In this paper, taking the design of reservoir for a sewage treatment plant as an example, this paper, based on the finite element calculation software, analyzes and calculates the settlement capacity of the foundation soil after the replacement of sand and soil, loads the earthquake load and calculates its The ultimate settlement of different soil under earthquake load.
