| 摘 要： | 塑性混凝土具有弹性模量低、极限变形大、弹强比小、变形性能好的特点,能有效地改善墙体应力状态.通过原材料和配合比选择,可以使塑性混凝土的弹性模量接近地基的弹性模量,而弹强比只有100～300;在满足抗压强度要求的同时不出现拉应力,从而能够避免墙体的开裂,这对防渗墙的整体抗渗性是有利的.同时,分析塑性混凝土的抗渗机理,认为塑性混凝土能满足防渗混凝土的力学性能和抗渗性能要求.

| Abstract: | Plastic concrete has low elastic modulus, high ultimate elongation and good deformation. By choosing raw materials and mix proportion, we can control the ratio of strength to elastic modulus between 100 and 300 and no tensile stress will happen, which is helpful to seepage control. Analyzing the mechanism of seepage control, shows that plastic concrete can been successfully used on seepage control concrete. |
