摘    要:光纤土工膜是具有破损定位功能的新型防渗材料。为了研究红土大坝中的光纤土工膜对坝坡稳定的影响,进行剪切强度试验和可调斜坡模型的抗滑试验,获得各种工况组合下膜–土界面的黏聚力、内摩擦角、滑动坡比、摩擦系数等数据。与纯粹红土组、红土内置复合土工膜组的数据进行比对分析,结果表明:光纤土工膜与红土的亲和性足以满足抗剪要求;光纤土工膜作为防渗体嵌入坝坡,在实际工程条件下的抗滑安全性能不低于传统土工膜,能够满足规范要求。

关 键 词:土力学防渗材料光纤土工膜界面亲和性

Abstract:Geomembrane with optical fibers is a new type of anti-seepage material,which provides a function of determining the cleft places itself. To study the stability of slope of the laterite dam embedded with the geomembrane with optical fibers,shear strength tests and anti-slide model tests were performed,so that test data about the membrane-soil interface,for example,the cohesion,the friction angle,the slip gradient and the frictional coefficient,were obtained. The data were compared with the ones of the pure laterite and of the laterite with the built-in composite geomembrane. The interface between the geomembrane with optical fiber and the laterite was found to have enough affinity to resist shearing. The anti-slide stability of the dam slope met the specified requirement if the geomembrane with optical fiber was used in earth dam.
Keywords:soil mechanics  anti-seepage material  optical fiber geomembrane  interface affinity
