某坝址河段巨型堆积体稳定性及工程影响地质研究

Preliminary study on giant accumulation stability and engineering impact of a hydropower project

金沙江上游某坝址河段，分布多个巨型堆积体，其集中分布，方量巨大，成为坝址选择的关键地质问题。通过对其物质组成、地质成因、稳定性、塌岸预测等方面的初步分析，预测它们对坝址河段成库条件的不良影响。

There are many giant accumulation mass distributed between the upper and lower dam sites of a hydropower project on Jinshajiang River. The giant accumulation group has a giant volume so it becomes a key problem for dam site selection. Through the preliminary study on matter consisting, cause analysis, parameter determination, stability analysis and bank collapse prediction, the impact of the giant accumulation group on the project is scientifically evaluated.
