为定量地认识孔压消散作用对土层抗液化能力的影响，通过建立描述在地震中动孔压的累积和消散耦合作用的物理模型，提出了估算振动砂石地基可液化性能的有限元分析方法，并结合原平─太原高速公路的可液化砂土地基的处理工程进行了探讨.
In order to quantitatively understand the effect of pore pressure dissipation on soil liquefaction resistance, a finite element analysis was conducted to estimate the liquefaction performance of vibrated sandy ground by establishing a physical model describing the cumulative and dissipative coupling of dynamic pore pressure during earthquakes. The method was discussed in conjunction with the treatment of liquefiable sand ground of Yuanping-Taiyuan Expressway.
