宁夏银北排水项目暗管排水外包滤料试验研究

An Experimental Study on Geotextiles used as Sub drain Pipe Filters in Yinbei Drainage Project in Ningxia

采用一维和二维渗透模型对土工织物作为农田暗管排水外包滤料进行了试验研究。试验用的 2种土壤取自宁夏银北暗管排水区 ,对 1 2种不同土工织物的透水效果进行了测定和对比分析 ,其初选结果将用于野外现场作进一步观测评价 。

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.
