Treatments on the collapsible loess canal basement in Nan'an canal of Xinjiang

结合国家重点工程建设项目,对新疆湿陷性黄土工程进行预浸水地基处理,从渠基处理及防渗处理两方面综合考虑,选择相对最佳处理措施,并根据以往工程经验,论证该处理措施的可行性及有效性,以防止渠水下渗导致湿陷性黄土渠基出现裂缝、陷坑及渠堤崩塌。

With the main national construction project, the prewetting method for ground treatment about collapsible loess in Xinjiang, complexly considering the handle of canal basement and seepage control, chooses the relatively best processing measure, and according to former project experience, proves the processing measure of his feasibility and validity, in order to avoid the infiltration of canal water who causes the collapsible loess canal basement to appear the crack, the trap and the ditch dike avalanche wet.
