    国道318线鄂西段南里渡滑坡成因分析

    ANALYSIS OF THE ORIGINAL OF NANLIDU LANDSLIDE IN THE WEST SECTION OF NO.318 NATIONAL HIGHWAY

    • 摘要: 通过勘察试验研究,认为南里渡滑坡形成主要内因是三叠系巴东组软硬相间的岩性组合和构造断裂发育所致.由于公路施工,改变了原地面的平衡状态,大量地表水渗人坡内,降低了强风化带岩体及斜坡土体的力学强度,形成了滑坡.其变形破坏方式,在滑坡的上、中、下部表现各异.在研究过程中,也分别作了论证,有望类似滑坡能予以借鉴.

       

      Abstract: On the basis of investigation and tests, We considered that the main internal cause of the Nanlidu landslide formation is a result of the soft and hard interlayered rock formation and the development of separation fracture of Badong gnup in Triassic.The road's construction changed the original equilibrium state of earth surface, A large amount of superficial water seeped into the slope, Which reduced the mechanical strength of highly decayed xrxk and slope soil, And finally formed the landslide. The deformations and failure modes of the landslide shows differences in its different parts.We gave demonstrations separately during our research and hoped that would be helpful while meet siamilar case.
