成兰铁路某地质灾害点崩塌及边坡特征分析

为了查明成兰铁路沿线茂县曲谷沟小学后山崩塌地质灾害的类型、结构形态、规模、变形特征及成因机制,对该崩塌地质灾害开展了工程地质应急勘查工作,采用地面测绘、探井、原位测试等多种勘查手段,查明该崩塌、教学楼的不稳定斜坡(陡坎)成因、类型、规模、范围、稳定状态及危害性,并分析其变形机制,表明:崩塌危岩体规模级别属中型,危害对象等级为一级,勘查地质条件类型为复杂,该灾害体治理工程等级为Ⅰ级。得到的结果可为进一步的评估防治工程提供参考。

Characteristics Analysis for the Falling and Slope of One Geological Disaster Place in Cheng-Lan Railway

In order to study the type,structural state,size and deformation characteristics,and genesis of the falling and slope of serious geological disaster place behind Qugugou primary school in Mao county,which is on the way of Cheng-Lan railway,the geological investigation is done to the falling and slope of serious geological disaster place.The method of area measuring,digging,insitu-testing are taken to study the type,structural state,size and deformation characteristics,and genesis of the falling and slope of serious geological disaster place of the school,the deformation of the falling and slope are analyzed.The results show that,the falling size is media,damage object is in the first state,the type of the surveying geological situation is complicated,and the degree of the reinforcement is I degree.The obtained results can give guidance for the further evaluation of the project.
