摘要
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 this paper the physical model for coupling the dissipation and accumulation of the dynamic pore pressure is established and the finite element procedure is programmed. The efficiency of the sand pile in dissipating the dynamic pore pressure in the foundation of the Yuanping-Taiyuan Highway was estimated with the theoretical approach.
