宝成铁路边坡变形机制分析及治理对策研究

通过宝成铁路下行线K313+950~K314+300段右侧边坡现场工程地质条件的系统调查，对坡体的岩体结构类型及其成因机制、结构面、坡面组合特征及其稳定性进行研究。研究结果表明，西区裂缝下方的崩塌体在暴雨或地震作用下，整体滑移的可能性大；裂缝上方的坡面结构松动，再次产生小型崩塌的可能性大；东区山体已被两条裂缝深切，目前已形成大体积的危岩体，产生大体积崩塌的可能性大。基于变形机制分析的治理措施，重点放在控制西部崩塌体整体滑移和东部危岩体的大体积崩塌上。

Study on Deformation Mechanism Analysis of Slope along Baoji-Chengdu Railway and the Treatment Countermeasures

Depending on the systematic survey of field engineering geological conditions of the right slope along the K313+950~K314+300 Section of Downline of Baoji-Chengdu Railway，the rock structures and their genesis，structural surface，combined feature of slope surface and stability are studied.The results show that the collapse accumulation below the cracks in the west district is very possible to slide as a whole under the action of rainstorm or earthquake，and the slope surface structure above the cracks is loose with large possibility of repeat small collapse；in addition，the mountain body in the east district has been cut off deeply causing large volume of dangerous rock mass with large possibility of large volume of collapse.The treatment countermeasures based on deformation mechanism analysis lays the stress on the control of overall slide of the collapse accumulation in the west and of large volume of collapse of the dangerous rock mass in the east.
