摘　　要：赤水市位于贵州省西北部,境内出露地层为侏罗系、白垩系红色建造,受自然因素和人类活动影响,地质灾害频发。赤水市两河口实验学校后方斜坡发生崩塌,危岩体崩塌后堆积在斜坡上,未下落到学校内。本文结合区域地质背景和水文地质条件,分析崩塌地质灾害特征,开展崩塌稳定性评价,以期明确崩塌成因和特征,为防治工程方案设计提供依据。经崩塌稳定性评价,若采取适宜的工程治理措施,则可消除崩塌地质灾害风险,确保周边人员安全和学校正常运转。Chishui City is located in the northwest of Guizhou Province,where the exposed strata are Jurassic and Cretaceous red formations,affected by natural factors and human activities,geological hazards occur frequently.The slope behind the Lianghekou Experimental School in Chishui City collapsed,and the dangerous rock mass piled up on the slope after collapse,but did not fall into the school.Based on the regional geological background and hydrogeological conditions,this paper analyzes the geological hazard characteristics of collapse,conducts a stability evaluation of collapse,in order to clarify the causes and characteristics of collapse,and provide a basis for the design of prevention and control engineering schemes.According to the evaluation of collapse stability,if appropriate engineering control measures are taken,the geological hazard risk of collapse can be eliminated,ensuring the safety of surrounding personnel and the normal operation of the school.
