摘要: 引入非饱和-饱和的渗流分析方法,考虑渗透系数以及饱和度与基质吸力之间的非线性关系,分析渗流场-应力场耦合机理和相互影响关系,并采用渗流场-应力场耦合有限元法对水位骤降下堤坝边坡位移场、孔隙水压力、超孔隙水压力进行具体分析。分析结果表明,利用渗流场-应力场耦合有限元法,比不考虑基质吸力和双场耦合作用分析,更加真实可靠。Abstract: The water rapid drawdown to the dyke slope stability influence is the present Geotechnical hot issues,This article mainly introduces the unsaturated transfusion analysis method,considered that between the penetration coefficient as well as the degree of saturation and matric suction ’s misalignment relations,the analysis infiltrates the flow field-stress field coupling mechanism and the mutual influence relations,under uses infiltrates the flow field-stress field coupling finite element method t...
