摘要:
基于多孔介质的渗流特性和土的非线性本构关系,研究了渗流场与应力场的耦合效应;根据弹性力学和渗流理论建立流固耦合数学模型及有限元格式;利用大型有限元分析软件ABAQUS对燕山水库土石坝建立非线性耦合模型,并对其进行流固耦合分析,计算结果表明:坝体中渗流与应力的相互作用是不可忽视的,考虑耦合作佣将对土石坝的稳定性产生不利影响.
Abstract:
Based on the seepage characteristics of porous media and the nonlinear constitutive relationship of soil, the coupling effect of seepage field and stress field was studied. According to elasticity and seepage theory, the fluid-structure interaction mathematical model and finite element format were established. The large-scale finite element analysis software ABAQUS was used to establish a nonlinear coupling model of the earth-rock dam of Yanshan Reservoir, and the fluid-structure interaction analysis was analyzed, and the calculation results showed that the interaction between seepage and stress in the dam body could not be ignored, and considering the coupling commission would adversely affect the stability of the earth-rock dam.
