复合土工膜厚度计算方法的应用比较分析

Application and Comparison Analysis of Calculating Methods of Composite Geomembrane Thickness

在分析防渗复合土工膜力学特性的基础上,结合仁宗海复合土工膜防渗堆石坝工程,分别采用顾淦臣薄膜理论公式、Giroud公式和前苏联经验公式三种确定土工膜厚度的方法对备选的两种规格复合土工膜进行厚度计算和选型分析,选择确定符合强度和变形要求且经济可行的一种复合土工膜。

Based on the introduction to the main mechanical properties of composite geomembrane, the paper respectively adopts three methods,i, e. ,Gu Gan-chen＇s membrane formulas, Giroud＇s formula and the former Soviet empirical formulas, to calculate the thickness of the two given types of composite geomembrane for the Renzonghai rockfill dam. Some comparison analysis is also done. Finally. the cconomical and suitable type of composite geomembrane is selected out,this type meets the demands of strength and deformation.
