摘要
对土工合成材料在地下排水、支挡结构物排水、路面中央分隔带及边缘排水、边坡排水等工程中的典型应用方式进行了总结.选择具有代表性的几种土工合成材料进行了大量的室内试验,着重研究了土工防排水材料的物理特性、水力学性能及力学性能,并对关键性能指标的测试方法进行了验证性研究,针对目前存在的问题提出了新的方法和指标.基于本次研究内容,并结合国内外相关成果,系统地提出了土工合成材料在公路排水设施中的新的设计标准与方法,同时建立了土工防排水材料应用技术分类方法.
The typical application schemes of geosynthetics in highway drainage engineering including underground drainage, retaining wall drainage, median separator drainage, edge drainage and slope drainage are summarized. The physic, hydraulic and mechanic performance of several representational geosynthetics are tested in abundant indoor experiments and the testing methods are estimated and emended with some new indexes. Based on all these conclusions and other domestic and overseas research results, new design criteria and methods for application of geosynthetics in highway drainage engineering are made. The classification method for application of geosynthetics in highway watertight and drainage engineering was established.
