土工膜的厚度應依據防滲和強度兩方面的要求來斷定-北京中瑞環?？萍脊こ坦?/title> <meta name="description" content="土工膜厚度應根據防滲和強度兩方面的要求來確定?？刂菩孤η袛辔廴驹从葹橹匾?。根據達西公式，滲透系數為10-12 cm/s 1 mm厚的土工膜與滲透系數為10-10 cm/s厚的土工膜相比，厚度約為20 cm，其滲透系數雖然相差100倍，但土工膜的滲透率卻比粘土高出兩倍。" /> <meta name="applicable-device" content="pc,mobile"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="Cache-Control"
