摘要
崩塌地质灾害点位于北京石景山山体顶部的功碑阁西侧附近的陡壁位置。山体主体走向为N34°W-S34°E,在山脊西侧附近断续分布着平行于山脊的陡立岩壁,沿山脊方向覆盖长度约170 m,岩壁上节理裂隙极为发育,认为其一旦发生崩塌,将对其下方景观小路上的过往游人及山脚下的既有“丰沙线铁路”安全造成严重影响。根据现场实际条件和工程经验,开展了治理工程设计,通过对治理方案的比选分析,最终选用了“全范围格构锚固”综合治理方案。通过本次治理达到了防灾减灾的目的,保障了人民生命财产安全。
The geological hazard site of the collapse is located on the steep wall of the overhanging cliff to the west of Shijingshan Mountain GongBei Pavilion in Shijingshan District,Beijing.The main direction of the mountain is N34°W-S34°E.There are intermittent steep rock walls parallel to the ridge near the west side of the ridge,covering a length of about 170 m.The joints and cracks on the rock walls are extremely developed.It is believed that once it collapses,it will seriously affect the safety of pedestrians on the landscape path below and the existing"Fengsha Line Railway"at the foot of the mountain.Based on the actual site conditions and engineering experience,and through comparative analysis,the comprehensive treatment plan of"full range lattice anchoring"was ultimately selected.Implementation of this plan has resulted in disaster reduction and ensured the safety of people’s lives.
