摘　　要：塑性混凝土具有大应变、低弹模、低强度等特性,能适应较大的变形,是经济优良的防渗体材料。通过陡坡水库除险加固工程应用的实例,总结了防渗工程采用先进行帷幕灌浆,再进行塑性混凝土防渗墙施工的方式或先进行塑性混凝土防渗墙,再进行帷幕灌浆的方式施工的优劣分析,为类似工程施工提供借鉴经验。Plastic concrete,as a kind of low cost and excellent impermeable material,has the characteristics of large strain,low elastic modulus,and low strength,which can adapt to large deformation.Based on the practical application of plastic concrete in Doupo Reservoir reinforcing project,the advantages and disadvantages of two construction methods are analyzed.One is to conduct curtain grouting first,and then construction of plastic concrete diaphragm wall;the other is construction of plastic concrete diaphragm wall first and then the curtain grouting,that could provide reference for similar project construction.
