【摘要】 研究了复合土工膜在砌石坝防渗工程中应用的可行性。首先进行了复合土工膜与砌石块粘结强度试验 ,试验结果表明 ,试块的破坏形式为脆性破坏 ,两者的粘结强度达到了C7 5砼的弯曲抗拉强度 ,完全满足工程要求。此外 ,实际工程观测也说明 ,砌石坝构筑复合土工膜坝面防渗体后 ,漏水量减少了 6 0 % ,防渗效果良好。更多还原

【Abstract】 Compound geotextile is mainly used in imperviousness of soil rocked dam. In order to study the feasibility of its application in rock fill dam imperviousness, the adhesion test of rock blocks to compound geotextile is carried out firstly. The result tells:the destroied form of tested blocks is brittle, the adhesive strength is reached to the bending strength of C7.5 concrete, it can satisfy the requirments of engineering uses. The measurement of actual works also explained that the use of compound geotextile in rock fill dam surface can reduce the amount of leakage water by 60%, the effects of imperviousness are obvious.更多还原
