Through these studies and analysis , following conclusions could be drawn : ( 1 ) it is necessary to study on harness engineering of landslide and dangerous rock since the main representations of this geological hazard are landslide and dangerous rock through geological investigation ; ( 2 ) it can be concluded though stability analysis that the dingzhuang landslide is stable naturally , which is identical to the in - situ investigation ; ( 3 ) through stability analysis , the landslide would slide if the water level dropped down from 175 . 10m to 156 . 0m and it rained successively after the three gorges reservoir work . ( 4 ) according to the results of calculation and the characteristic of the landslide , it is suggested that such measures as unloading at upper part , anchorage and pile supporting system and drainage system should be used on the landslide . ( 5 ) according to geological investigation , there are three kinds of dangerous rock in the engineering , those are failing - down rock , collapsing rock and sliding rock 因此有必要对滑坡进行治理； ( 4 )根据滑坡推力计算结果和本滑坡属牵引式滑坡的特点，滑坡体上部相对较稳定，中下部处于基本稳定或不稳定状态，因此建议此滑坡治理采用上部削坡减载与锚拉抗滑桩、挡墙进行支挡结合的处理方法，同时结合截排水等措施进行综合治理； ( 5 )根据地勘资料，通过对危岩体的形态、规模、基座和底界层及分布特点和分析，将本工程危岩体失稳崩塌的方式归纳为坠落式、倾倒式和滑塌式三种类型并分别提出相应的稳定性计算方法； ( 6 )分别对本工程中的危岩体进行了稳定性计算，并且发现其都处于不稳定状态，因此根据实际情况分别提出相应衬砌支撑和清理等加固治理措施，最后还对加固后的危岩体进行了校核计算，满足要求。
Based on the summary of the inspection effect for one hydrogeological year of stage geological disaster prevention project of xingshan county in three gorges region , this paper puts forward the relevant and effective methods for the harnessing of landslide , dangerous rock body , collapsed bank and other different geological disasters , and proposes suggestions for the future inspection of geological disaster prevention projects 摘要本文通过对三峡库区兴山县二期地质灾害防治工程一个水文年的效果监测总结，提出了针对滑坡、危岩体、塌岸不同地质灾害体的抗滑桩、格构、挂网喷砼等不同治理工程所应采取的与之相适用、而有效的监测方法、监测频率，以及资料整理、工程效果分析时应注意的问题等，为今后做好地质灾害防治工程监测提出建议。
In this thesis , dangerous rock was classified into three styles : cantilever dangerous rock , wall - pillar dangerous rock and pyramid dangerous rock . the ansys software is used to analyze the collapse pattern of each style . based on this conclusion , the calculate method used in engineering is provided at last 为了方便对危岩进行工程加固，本文把危岩分为悬挑式、墙柱状、棱形体三类，运用ansys有限元软件对各类危岩的破坏模式作了比较细致的分析，然后以支撑和锚固为主要手段，针对每一类危岩构建了不同破坏模式下的工程设计计算方法。
