摘要
危岩体是影响人类生命财产安全与工程活动的自然地质灾害之一,故对危岩体的勘察、稳定性评价与防治是地质灾害防治的研究难题。通过本次现场大量调查和综合分析,对巴鹤高速公路K182+400～K183+090段高边坡危岩的变形破坏类型、破坏特征、影响因素等进行研究,归纳出场区主要的变形破坏模式为:倾倒—拉裂、滑移—拉裂和坠落式3种模式。同时根据变形破坏特征对其进行稳定性分析、评价,最后对危岩区提出防治建议。
Dangerous rock is one of the natural geological disasters affecting human life and property safety,and engineering activities.Thereafter the exploration to dangerous rocks and stability evaluation are the study problems in geological disasters' prevention and cure.Through this mass survey on site,and comprehensive analysis,we study the type of deformation and damage,the feature of deformation,influencing factors about dangerous rocks of K182+400～K183+090 slope in Badong-Hefeng highway.And we sum up three modes of deformation and damage: dump-crack,slippage-crack and falling.At the same time,we make a stability analysis and evaluation to the Badong-Hefeng highway according to the feature of deformation and damage.At last we raise some suggestions to the prevention and cure to the area of dangerous rocks.
