复合土工膜缺陷渗透量试验观测

Observation of Leakage due to Defects in Geomembranes

结合某复合土工膜斜墙坝工程材料实际情况,自行设计试验装置,进行复合土工膜缺陷渗透量试验研究,经长期观测得到复合土工膜在不同缺陷孔径、不同水头作用下的缺陷渗透量实测值。分析了复合土工膜的缺陷渗透作用机理及相关因素对其影响,为土工膜的防渗设计提供依据。

Combine the actual engineering-composite geomembrane tilting core dam, a seepage instrument is designed to test the leakage due to defects geomembranes. Gained the real leakage due to defects in geomembranes under different aperture of damnification, different water pressure. Analyzing the primary factor that influences the magnitude of leakage due to defects in geomembranes. The study will offer the reference basis for the design of geomembranes.
