Abstract: On the basis of investigations to immigration sites in Yunyang , Wanzhou , Fengjie and Fulin regions in Chongqing resevoir , author take Shuangjiang immigration site , locating in Yunyang county , as an example and approach deformation and strength feature of the site under kinds of structure in this paper .Using horizontal displacement , Lode stress and strain energy from FEM simulation to the site , the author fund optimal object function and conclude optimal loading constuction of engineering structures in the site .The results are valuable to guide immigration site construction in Chongqing reservoir

Key words: Sanxia immigration site , engineering structures , optimal loading construction

摘要： 笔者根据对重庆库区内云阳、万州、奉节、涪陵等地区大量移民址区的现场调研，以云阳双江移民址区为 原型，分析了在不同工程结构物及其组合情况下移民址区地体的变形及强度特征。基于有限元数值模拟成果通过 专家系统法选用水平方向位移、Lode应力参数和应变能u构建了址区稳定优化目标函数，据此分析，获得了移民 址区的优化施工工况。研究成果对于移民结构物建设具有重要指导作用，也为移民址区评价提供了量化指标
