北京百泉山风景区崩塌地质灾害防治方法分析

Analysis on Treatment Method of Rockfall Geological Hazard in Beijing Baiquanshan Scenic Spot

以北京百泉山自然风景区不倒翁景点附近的崩塌地质灾害为例,系统介绍该处危岩带(体)规模、特征、破坏模式、危害程度等情况,并根据其地质灾害特点、发育程度及沟谷内交通等条件,对多种治理方案进行分析、比选,最终选择了对危岩带上部反倾区进行削方,清除危岩体及陡壁坡面浮石、松动岩块,对危岩带采用挂主动防护网的治理措施。本治理方案可为类似山谷型自然风景区地质灾害治理工作提供一定的借鉴。

With the example of rockfall geological hazard in Beijing Baiquanshan scenic spot, this paper systematically introduces the hazard about the dangerous rock belt （mass） scale, dangerous rock characteristics, damage mode and damage degree, etc. , and according to the geological hazard characteristics, development degree and the traffic conditions in the valleys, the analysis, comparison and selection are made on variety of treatment schemes, the final choice are cutting down earth on the upper anti-dip part of the dangerous zone to remove the dangerous rock mass, float stones on steep slope and loose rock mass and hanging active protection net. This scheme can be used as a treatment reference for the similar geolog- ical hazard of natural scenic spot in valley.
