Friction tests in moving water and field sheer tests and seepage model tests and the effects of seepage defending and rough ratio tests and the capacity of resisting from frozen bulge and ice pressure. 2. Through the series track ageing tests of geosynthetics for 14 years, if the covering is 40cm thick and the initial strength is more than 500N/5cm, the geosynthetics can be used for at least 50 years, most to be more than 100 years. Under the same conditions, the strength and elongation of geotextile are both decrease, and for geomembrance the strength increased in early days. One important ageing index for geomembrance is embrittlement.

2通过工程现场14年的取样，进行老化试验分析，结果显示，土工合成材料在40cm厚以上岩土严密保护的条件下，初始强度大于500N/5cm，使用年限至少可达50年，多数情况可超过100年；在同等条件下，土工织物老化在力学性能上的表现是强度和延伸率都呈下降趋势，而多数土工膜在初期力学性能上表现是强度增加延伸率下降，到后期强度和延伸率才都呈下降趋势，脆化是衡量土工膜老化性能的重要指标。
