肖家湾危岩体稳定性评价与防治对策OA
Assessment on Stability of Dangerous Rock Mass in Xiaojiawan and Countermeasure
为促进危岩体的防治和汶川地震后的重建工作,从地质结构、地形地貌和变形特征分析了肖家湾危岩体的形成机制.在此基础上,采用赤平极射投影和极限平衡法对该区危岩的稳定状况进行了定性与定量分析评价.经分析判断危岩均处于不稳定状态,需进行治理.针对每个危岩体的具体特征,提出了人工清理+砂浆锚杆+砂浆填缝+凹腔支顶+拦石墙+ SNS被动防护网等综合治理对策,取得了良好效果.
In order to promote prevention of dangerous rock mass and reconstruction after the Wenchuan Earthquake, the formation mechanism of dangerous rock in Xiao Jiawan is studied in terms of geological structure, topographical landform and deformation characteristics. On this basis, the stability of the dangerous rock mass are qualitatively and quantitatively evaluated by means of stereographic projection and limit equilibrium method. The results of the study show …查看全部>>
