摘要
PVC土工薄膜与针刺土工织物相结合的复合土工薄膜具有非均质、各向异性及多孔性等特征，是一种隔热性能良好的工程材料。对复合土工薄膜的热扩散系数进行了试验。并结合工程实例对其隔热作用进行了计算分析，以论证其隔热效果。
Owing to its nonhomogeneity, anisotropy etc. geotextile / geomembrane composite,composed of PVC geomembrane and needlepunched geotextile, is a kind of engineering material with good thermal insulation, experiments are made on its thermal diffusivity.Simultaneously, combined with engineering examples, thermo-insulation of the geomembrane composite is computed and analyzed, and its results are verified.
