摘要
为研究复合土工膜对路面结构承载力的影响,采用贝克曼梁法,分晴天和雨天工况对普通路面结构以及加入两种不同复合土工膜的路面结构进行了弯沉值测定。试验结果表明:复合土工膜在一定程度上提高了路面结构的承载力,且在雨天工况下,复合土工膜能阻隔水分,保护地基,其加固作用更加显著。为复合土工膜在同类工程中的应用提供了设计依据及参考。
Based on the Beckman beam method,in sunny and rainy conditions,the deflection values of ordinary and two composite geomembrane pavement structure were studied to analyzing the influence of the composite geomembrane on the pavement structure.The test results indicated that the composite geomembrane could not only improve the bearing capacity of pavement structure,but also block the water and protect the foundation in the rainy conditions.And the study results could provide the design basis and reference for the application of composite geomembrane in similar projects.
