牡丹江市天仙宫滑坡稳定性分析与治理措施

天仙宫滑坡严重威胁黑龙江省的著名道教圣地天仙宫和201国道的安全。通过勘察查明了天仙宫滑坡的滑坡形成机理,结果表明,新发育的滑坡在自重情况下滑坡处于稳定状态;在现状地下水位情况下,滑坡处于欠稳定状态,在暴雨加地下水位状态下,滑坡处于欠稳定-不稳定状态,滑坡失稳可能性较大;原有滑坡处于稳定状态。针对滑坡体设置了抗滑桩、地下排水盲沟、地表截排水沟等综合治理方案,至今运行效果良好。

Stability Analysis and Control Measures of Fairy Palace Landslide in Mudanjiang City

The Fairy Palace landslide seriously threats the safety of the famous Taoist holy land Fairy Palace and 201 National Road in Heilongjiang province. The forming mechanism of Fairy Palace landslide is found out through survey, and the results show that the new developed landslide is stable in the case of gravity but under the condition of the current underground water level, the landslide is understable. Under the condition of heavy rains and underground water level, the landslide is understable-unstable, with high probability of landslide instability. The old landslide is in the stable state. Comprehensive control measures including anti-slide piles, underground drainage and surface drainage are set up according to landslide mass; the running effect is good so far.
