通过对玄武地震液化和地面变形的现场调查，发现液化地面发生了较大的变形。为了模拟液化引起的大变形，需要一种能够描述大变形的液化分析方法。本文的目的是提出一种基于有限变形理论的弹塑性本构模型液化分析方法，该方法采用了位移孔压和位移相对位移孔压的表述方法。首页--期刊细介绍--期刊题录与文摘--期刊详细文摘内容
From the field investigation of liquefaction and ground deformation due to Hyogoken Nambu Earthquake, we have found that large deformation occurred in the liquefied ground. In order to simulate a liquefaction induced large deformation a liquefaction analysis method that can describe large deformation is necessary. The aim of the present paper is to propose a liquefaction analysis method by an elasto-plastic constitutive model based on finite deformation theory using both u-p (displacement pore pressure) and u-w-p (displacement relative displacement pore pressure) formulation techniques.
