| Abstract: | The permeability of 12 types of geotextiles, used as sub drain pipe filters, were tested and compared under two kinds of soils sampled from Ningxia Yinbei Drainage Project area. The preliminarily selected geotextiles, based on the test results, will be further tested and evaluated in fields and these experimental data will be important reference for selection of proper filters for Yinbei Drainage Project area. |
