新疆大西沟水库坝基砂层的勘察与评价

Evaluation and reconnaissance on sand layer under dam foundation of Daxigou Reservoir in Xinjiang

针对新疆大西沟水库坝基下河床内的砂层透镜体的液化问题进行了规范规定的野外勘探试验研究和相应的室内研究工作,使工程的饱和砂层的振动液化问题得以解决,取得了较好的效果。

Both the field reconnaissance and the related indoor study specified in the specifications concerned are made on the liquefaction of the sand layer in the river bed under the dam foundation of Daxigou Reservoir in Xinjiang,from which the problem from the vibrating liquefaction of the saturated sand layer during the construction of the project is solved with a better effect.
