玉印山危岩带稳定性评价及其加固措施

摘要

Yuyinshan dangerous rock is a typical dangerous rock band with complex forming conditions,various types,special location and large harm. For the numerous dangerous rocks,using classification and survey evaluation method,we analyze and calculate for each rock,and take various measures,such as block gap and support,to reinforce the dangerous rock,and achieve good effect.%玉印山危岩是一个典型的形成条件复杂、类型多样、地理位置特殊、危害比较大的危岩带.针对这种危岩个数多,成因复杂,四面临空的危岩体,采取分类调查评价方法,对各个危岩块体进行分析、计算,根据每一个危岩块体的具体情况,分别采用了清危、补缝、支顶、挑梁、锚杆、锚索、被动网等方法或各种方法组合的措施对危岩进行加固处治,效果良好.
