  混凝土面板堆石坝上游坡面传统的垫层料超填、削坡、斜坡碾压的施工方法存在许多弊端。
• Therefore through a stress analysis to transition layers and main core , it is studied to improve stress conditions by canceling auxiliary core so as to make direct contact between main core and transition materials
  因此通过对过渡层与心墙应力状态分析，研究取消副墙，主墙与过渡料直接接触，来改善应力条件。
• This kind of structures will cause the principal stress difference bigger due to the sharp changes modulus of deformation between auxiliary core and main core , auxiliary core and upstream and downstream transition materials , which is disadvantage of stress transmission
  该种心墙的结构型式，由于副墙与主墙、副墙与上下游侧过渡料的变形模量发生突变，不利于应力的传递，造成主应力差值偏大。
• Extruded concrete curb technology was introduced in 20th congress icold held in beijing in year 2000 , this method draw more attention for its improving the compaction of transition material , excellent performance of slope protection , and convenient construction . this extruded concrete curb technology was developed in ita dam construction in brazil , the ita method consists of building and extruded concrete curb by using an extruding machine before the construction of a layer of the transition material , then spread and level the transition material in layers inside the curb , and compact the layer by vib ' ratory roller horizontally
  巴西工程界在埃塔( ita )面板堆石坝建设中，借鉴道路园林工程中道沿机的挤压滑模原理，创造性使用边墙施工法，在每填筑一层垫层料之前，用挤压式边墙机制作出一个半透水混凝土小墙，然后在其内侧按设计铺填坝料，用振动碾平面碾压，合格后重复以上工序。
