补充资料：土工织物
用合成纤维纺织或经胶结、热压针刺等无纺工艺制成的土木工程用卷材，也称土工纤维或土工薄膜。合成纤维的主要原料有聚丙烯、聚酯、聚酰胺等。土工织物按其用途分为滤水型、 不透水型及保温型。宽度为1～18米。长度不限。土工织物的厚度与成型方法有关，每平方米的重量从16克到900克不等。 ①滤水型土工织物允许水通过，而阻止细粒土随水流失。其用途可以代替管道作为排水盲沟；道路中作为渗滤层，以防止翻浆冒泥；软弱地基上作为堤坝的垫层，以提高地基的稳定性；或隔离两种不同粒径的土粒，以免混合。②土工织物表面敷以不透水的涂层即成为防水型，可以作为渠道的防渗漏铺面，也可作为房屋基础中的防潮层。③保温型土工织物，用于寒冷地区作为地基的保温隔层。
由于用途不同，土工织物的强度也不同，通常它的抗拉强度、抗撕裂强度、耐冲压强度及极限伸长率都较大；埋在土壤中的耐腐蚀性和抗微生物侵蚀性也都良好。
