高陡边坡与危岩体治理施工安全综合防治技术研究

Study on Comprehensive Prevention and Control Technology for Construction Safety of High and Steep Slope and Dangerous Rock Mass

拉哇水电站坝址区高陡边坡开挖及危岩体处理存在诸多不可预见的安全隐患和危险源。一是危岩体分布范围广、数量多、高差大、两岸地形高陡,交通极为不便,为危险源的治理带来很大的困难。二是施工作业环境复杂、难度大、技术要求高、环水保任务重。通过对现场的治理勘察拟采取主动治理及被动防护措施予以防治。本文就危岩体治理施工及综合防治进行详细探讨研究。

There are many unforeseen potential safety hazards and hazard sources in the excavation of high and steep slopes and the treatment of dangerous rocks in the dam site area of Lawa Hydropower Station.First,the dangerous rock mass has a wide distribution range,large quantity,large elevation difference,high and steep terrain on both banks,and the traffic is extremely inconvenient,which brings great difficulties to the treatment of hazard sources.Second,the construction environment is complex,difficult,high technical requirements and heavy environmental and water conservation tasks.Active control and passive protection measures will be taken to prevent and control the site.This paper discusses in detail the construction and comprehensive prevention of dangerous rock mass.
