Research on Durability of Geotextile by Taking Field Samples from Completed Works

Based on the results of the tests on the geotextile samples taken in-situ from the experimental dams built for the regulation of the waterways in the Changjiang River between Jiepai and Hanjiang and the available test results of the geotextile used in other projects both at home and abroad,the influence of the material and texture of geotextile upon the durability of geotextile when it is used for different aims is analyzed and the durable life of the geotextile commonly used in various works is proposed.
