摘要
对比了国内外现行的土工织物垂直渗透试验测试标准及参数取值方法,总结了测试过程中的影响和控制因素,包括试验用水条件、试样饱和程度及仪器结构设计等方面的研究现状,分析了垂向压力、拉伸应变及覆土情况对土工织物垂直渗透特性的影响及相关研究成果,并对仪器改进、数据处理的规范化及试验工况与实际应用工况的一致性等方面提出了研究展望。
In this study we compare the existing test standaMs for vertical infiltration of geotextiles along with the parameter selection method, both at home and abroad. The influence and control tactors including the conditions %r water supply and the saturated degree of sample during the test, as well as the research status of structural design of test equipment, are summarized. Additionally, we analyzed the influences of vertical pressm＇e, tensile strain and cover soil on the vertical infiltration of geotextiles. The analysis sheds light on the improvement of test equipment, the standaMization of the data processing, the consistency between the test condition and the working conditions in practical.
