摘要
复合土工膜是一种性能可靠的防渗材料。目前在确定土工膜厚度时,曲线交会法是一种最简便,最常用的方法。利用曲线交会法结合工程实例,确定复合土工膜的厚度及选择适当的型号,通过全苏水工科学院公式进行验证,发现用曲线交会法求得的膜厚度能满足实际工程需要。经工程运行,所选复合土工膜防渗效果很好。
The composite geomembrane is a reliable impermeable material and curve intersection method is the most simplest and convenient and the commonest method to calculate the thickness of the composite geomembrane. In this paper, curve intersection method with engineering examples was used to determine thickness of composite geomembrane and choose proper models. Finally, the test of soviet hydraulic engineering academy formula found that the thickness of composite geomembrane calculated by curve intersection method could meet the needs of projects. Project practice proved that composite geomembrane had a good effect of impermeability.
