为了解我国土工合成材料检测的现状 ,清华大学和土工合成材料协会联合全国多家生产厂家和检测单位 ,进行国内首次“背靠背”式的土工合成材料联合测试。结果表明 :力学和水力特性测试方面的数据离散很大。这说明我国目前土工合成材料测试规范一些项目有待明确 ;另外还说明 ,目前各实验室的管理、技术水平、操作等方面尚有差距 ,亟待改善。 In order to understand the status quo of geosynthetics testing in China, Tsinghua University and Geosynthetics Association, jointly with a number of manufacturers and testing institutes in the country, conducted the first joint test of “back-to-back” geosynthetics in China. The results show that: the mechanical and hydraulic characteristics of the test data discrete large. This shows that China’s current geosynthetics test specifications for some projects to be clear; also shows that the current laboratory management, technical level, operation and so there is still a gap, in urgent need of improvement.
