尼尔基水利枢纽工程粘性土分散性分析的研究

尼尔基水利枢纽位于黑龙江省与蒙古交界的嫩江干流上,工程基础可能存在分散性粘土。由于分散粘土对水利工程的危害极大,有必要对该工程使用的土料进行分散性鉴定。本文通过三种试验方法鉴定得出统一结论,判定该批土样为非分散性土。

An Analysis on the DisDersion of Cohesive Soil of Nierji Hydro-iunction Project

Nierji Hydro-junction Project is located in the mainstream of Nen River in the junc- tion of Heilongjiang and Mongolia, and there may be dispersive clay in its engineering founda- tion. Dispersive clay has a great harm on hydraulic engineering, so it is necessary to identify the dispersion of used soil material in this engineering. Based on the identification by three test methods, it is concluded that this batch of soil sample is non-dispersive clay.
