【摘要】 在实际工程中,土工膜擦痕损伤往往被忽视,而施工中擦痕损伤几乎是难免的。针对土工膜的损伤做了以下几个方面的研究工作:通过试验总结出不同土工膜损伤后的应力应变和顶破强度等方面的规律,得出了土工膜的顶破强度与损伤度的关系;根据试验结果,计算土工膜损伤后对防渗效果的影响。更多还原

【Abstract】 In actual engineering, the scratching damage to the geomembrane, which is inevitable in construction, is normally neglected. Research against the scratching damage to the geomembrane is done in view of the following aspects: laws on the stress, strain and strength of the geomembrane under various kinds of damages, and the relations between the strength and its damage degree; the effect of the damage on the antiseepage performance of the membrane.更多还原
