新疆南岸干渠含盐渠基处理方案

Treatment of Saline Foundation of Main Canal of South Bank in Xinjiang

新疆南岸干渠工程渠道末端4.3 km高含盐砂砾石渠基,盐分以易溶盐、中溶盐、和难溶盐形式存在于土体中,其中易溶盐、中溶盐在水流作用下易迁移,造成基础溶陷性破坏。通过勘查研究提出了换填处理技术方案并进行了成功处理,具有良好的经济性。

There is the high saline sandy gravel foundation of main canal of South Bank in Xinjiang, which locates its end and 4. 3km long. The saline matter as the soluble salt, insoluble salt forms exists in the soil, in which the soluble salt migrates easily under the action of water flow to result the karst depression disruption for foundation. Based on the survey, the replacement treatment is used successfully.
