塑性混凝土配合比设计及试验方法探讨

Inquiry into mix design and test method of soil concrete

塑性混凝土已成功应用于三峡二期围堰防渗墙。结合工程实际探讨了塑性混凝土原材料的选择和配合比设计的基本方法 ,并总结了塑性混凝土的物理力学性能和参数试验方法。试验表明 ,优化配合比设计后的塑性混凝土能满足防渗墙良好的变形和防渗性能的工程设计要求。

Soil concrete has been successfully used on the cutoff wall construction of the second stage cofferdam of Three Gorges Project. In connection with engineering practice the selection of raw materials and mix design of soil concrete are explored, and its physical properties and test methods of mechanical parameters are summarized. The test results show that optim ally designed soil concrete can satisfy the demands of cutoff wall in aspects of extensive deformation and seepage prevention.
