土工合成材料工程特性试验研究

Experimental investigation of engineering characteristics of geosynthetics

通过室内试验 ,对相同种类和不相同种类土工合成材料的物理力学特性、渗透特性、反滤特性和加筋特性等工程特性进行了试验研究 .结果表明 ,土工合成材料的质量性能差异较大 ,根据工程使用的情况不同 ,应该选择不同的土工合成材料 .在工程施工中 ,应根据当地的土壤特性和工程要求 ,严格按设计、规范要求进行选择材料 .

Various kinds of geosynthetics are tested i n laboratory to study their engineering characteristics and physical and mechanica l properties such as, permeabilities, filter abilities, and reinforcement charac teristics of geosynthetics. The results show that the difference in these proper ties among the different geosynthetics is significant. It is concluded that diff erent materials should be selected for different engineering purpose. In the pro cess of construction, such selection shall be based upon the local earth conditi on, engineering requirement, and the design specifications as well.
