“500”水庫受水區(qū)西延干渠邊坡土工膜防滲體抗滑穩(wěn)定試驗(yàn)研究
[Abstract]:In recent years, geomembrane anti-seepage technology has developed very rapidly in China, and various geosynthetics have been gradually applied to different hydraulic structures. However, there are still some technical problems in the application of geomembrane. At present, due to the different experimental instruments used by researchers to study the interface friction characteristics of geomembrane, benzene plate and other materials and soil, the relevant data and results obtained are also different. Therefore, the stability analysis of slope and dam slope is more difficult, and the friction characteristics of benzene plate and geomembrane, benzene plate and soil are not analyzed experimentally, and the interfacial action between them determines the stability of slope protection to a great extent. In this paper, according to the concrete engineering example of "500" reservoir, the different conditions of the recent project of "500" reservoir in the west extension main canal, the gravel cushion material and the foundation soil material, the benzene plate, the composite geomembrane and the benzene plate are introduced. The friction angle and cohesion between the mortar and the benzene plate were tested and studied. According to the test data of the main canal and the south trunk canal already done in the project of "leading Ejek, Jiwu", the polyethylene light film in different states was separately used. The friction angle and cohesion between the composite film and mortar are summarized, which provides the basis for the structural design of the west extension canal in the "500" reservoir. At the same time, it also provides a reference for the slope stability analysis of the channel.
