摘要:
略阳县南山滑坡多次出现复活的迹象,严重威胁了滑坡体上及坡下的几十栋办公楼、住宅楼及近2000人的生命财产安全。本文通过对滑坡的调查,钻探及室内试验,分析了滑坡蠕动变形及可能复活的原因。利用滑坡稳定性计算的结果对其危险性进行了评估,结果表明滑坡在正常状态下是稳定的,但是在饱水及地震等不利工况下,坡体有失稳的可能,特别是滑坡前缘的陡坡段发生破坏的可能性大,需要采取措施进行治理。

Abstract:
The resurrection signs of Nanshan landslide, which is in Lueyang County, Shaanxi province, have been appeared many times. It seriously threatens dozens of office buildings, residential buildings and nearly 2000 residents' lives and their property safety. Through investigation, drilling and testing, three reasons made the Landslide creep deformation and the possible resurrection. The stability calculation shows that the landslide is stable in normal circumstance, but in adverse conditions such as saturated or earthquake, landslide will lose stability in whole, it should be noted that it is more dangerous at steep slope section of frontal edge of the landslides. Therefore, it needs to take measures to control.
