思南东互通管理区大型滑坡变形机理分析与治理措施

Analysis on Deformation Mechanism of the Large Landslide at Sinan East Interchange Management Zone and the Treatment Measures

思南东互通管理区滑坡发生后,进行了多种手段的地质勘察工作,但勘察结果似有多处矛盾,难以对这一危害巨大的滑坡做出准确定性和评价。对此,全面分析了该滑坡的变形机理,指出看似矛盾的数据其实是该滑坡变形过程和机理的真实反映,是掌握该滑坡特点的基础资料。分析结果证明:在分析滑坡变形机理的基础上,有针对性地提出了治理滑坡的措施,治理结果表明,治理措施取得了明显效果。研究成果对同类型滑坡的勘察评价及治理具有参考价值。

After landslide arose at Sinan East Interchange Management Zone, geological survey by various means was carried out, however, it seemed that many contradictions existed in the survey results so that the landslide having large hazard was difficult to be classified and evaluated properly. In this paper, the deformation mechanism of this landslide was analyzed comprehensively, demonstrating that the data seemed contradictory were, actually, not only the real reflection of the deformation process and mechanism, but also the basic information to understand the landslide＇s characteristics. The study result has proved that the treatment measures proposed depending on the deformation mechanism have obvious effect, and has important reference value to investigation, evaluation, and treatment of similar landslide.
