【摘要】 北京市怀柔区响水湖景区长城磨石口关北侧山坡,由于修建景区道路切坡形成崩塌危岩带(体),威胁景区人员、文物及道路设施安全。区内危岩体崩塌失稳主要为滑移式和倾倒式两种破坏模式,选择危岩带中的典型危岩体进行稳定性计算分析,以及运动特征分析。经计算分析,边坡危岩带(体)在天然工况下处于稳定状态,在暴雨和地震工况下,抗剪强度降低,多处于欠稳定状态,潜在发生崩塌的可能性,可作为后期治理依据。更多还原

【Abstract】 The slope on the north side of the Great Wall of the Xiangshui Lake Scenic spot in Huairou District of Beijing has formed collapse dangerous rock zone(body)because of the construction of the road cut slope in the scenic area,which threatens the safety of the scenic area personnel,cultural relics and road facilities.The collapse and instability modes of dangerous rock mass in this area are mainly slip type and overturning type,and the typical dangerous rock mass in dangerous rock zone is selected for stability calculation and analysis,as well as the analysis of motion characteristics.Through calculation and analysis,it is found that the dangerous rock zone(body)on the slope is in a stable state under the natural working condition,and the shear strength decreases under the heavy rain and earthquake conditions,most of which are in an unstable state and the possibility of potential collapse occurs.The above calculation results can be used as the basis for later engineering treatment.更多还原
