塑性混凝土防渗墙在平原水库工程中的应用

Application of plastic concrete vertical cutoff wall in construction of reservoirs in plain area

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。通过南水北调东线双王城水库工程应用的实例,总结了在沿海地区,地下水水质为硬咸水~卤水的易塌孔地质条件下塑性混凝土垂直防渗墙施工工艺,为类似工程施工提供借鉴经验。

Plastic concrete,featured as large strain,low elastic modulus and low strength,can adapt to relatively big deformation and be used as economical seepage prevention materials.Taking Shuangwangcheng Reservoir in the Eastern Route of South-to-North Water Diversion Project as an example,it summarizes the construction technology of plastic concrete vertical cutoff wall in coastal areas under the geological conditions of collapsing hole and brackish water and brine in the aquifer.The case study can provide valuable experiences for the construction of similar projects.
