西藏某水电站安置点危岩工程影响研究

西藏某水电站安置点边坡危岩发育，稳定性差-极差，危险性大，存在失稳的可能，极大威胁安置点人员和财产安全以及省道通行安全。本文对安置点边坡危岩的稳定性进行了评价，对危岩的危险性进行了分级，并利用日本道路公团法和RCOKFALL软件对危岩的冲击力、落距、弹挑高度、总动能、水平运动距离进行了分析，得出了危岩的运动距离与安置点的关系，最后提出了合理的防治措施建议，为危岩治理提供了科学的依据。

A RESEARCH ON THE UNSTABLE ROCK PROJECT ON THE SETTLEMENTS IN A TIBET HYDROPOWER STATION

The settlements in tibet hydropower station has a lot unstable rocks, poor stability~very poor stability, risk of large may collapse, and have a serious threat to people and property in settlements and the highway traffic safety. In this paper, have an evaluation and grading on the risk of unstable rock, by using the Highway Public Corporation Law of Japan and the ROCKFALL software, analysis the falling distance, jumping height, the total kinetic energy, horizontal movement distance of the unstable rock, and obtain the relationship between the movement of unstable rock and the settlements, finally, give a reasonable prevention recommendations and a scientific basis.
