6)  embankment on soft soil
软土路堤
1.
During the construction of embankment on soft soil ground, people are accustomed to small deformation hypothesis, namely the hypothesis soil body subsidence deformation enough slightly, such hypothesis may simplify the question very good and has the good serviceability in practical.
针对这种实际情况,本文运用大变形理论有限元法对软土路堤稳定性进行了研究,主要做了如下几方面的工作: 一、由于软土边坡在失稳破坏时,会发生相当大的位移和变形,单元应变可能达到10%或20%以上,为更好的模拟实际情况,利用大变形有限元强度折减法对路堤进行稳定性研究,并与小变形的分析结果作了比较。
补充资料:多种土质坝
      采用两种以上筑坝材料筑成的土坝。坝体包括防渗料和各种透水料。防渗料置于坝体中间或上游,再按排水过渡原则分别设置由中间向上下游,或由上游向下游透水性逐渐增大的坝壳透水料(见图)。这种坝适用于当地具备几种筑坝材料(包括从建筑物开挖出来的石碴),且必须用两种以上材料才能满足数量要求的情况。
  
  这种坝的优点:①可因地制宜充分利用包括石碴在内的当地各种筑坝材料;②土料用量比均质土坝少,因而施工受气候影响也相对小;③如防渗体设于上游,雨天可先填下游透水料争取工期;④坝内自防渗料起按由细到粗的排列过渡原则分区配置筑坝材料,有利于坝体排水,简化排水设施,使下游透水坝壳浸润线较低。如防渗体位于中间,当库水下降,上游透水坝壳的孔隙水迅速外排,上游坝坡可设计得比较陡。如防渗体位于上游,下游坝壳全为透水料,下游坝坡比较陡。综上所述,这种坝型比均质土坝节省工程量。其缺点是坝体由多种材料组成,工序复杂,施工干扰大。
