针对白砂岩能否用于水渠渠底的填充料问题，进 行了试验研究。白砂岩的性状是介于硬土与软岩之间，被扰动后呈松散状。通过试验证实： 细沙、中细砂经压实后，均有较好的压实性，不产生膨胀，属弱冻胀，极微透水，低压缩性 ，较高的抗剪强度，这些特性指标均能满足工程要求。这种材料已用于工程中，经过4年的 通水运行，工程状况良好。

For understanding the properties of the white-sand rock in Zhungaer basin being used as filling materials of cha nnel foundation, a test study was performed. The characteristic of the white-sand rock is between the hard soil and soft rock. It will becom e loose when this rock is disturbed. The test result shows that, by compaction, fine sands and mid-fine sands of the rock possess the charac teristics of non-expansion, weak freeze-expansion, exceedingly light perviousness and high shearing strength. The materi al was used in some engineering, which has run for 4 years, and the channel is i n good order.
