Abstract:

针对崂山地区典型的青山滑坡地质灾害点,开展滑坡发育特征和地质环境调查,分析了与滑坡发生相关的地形地貌、水文地质、工程地质等条件。综合各因素分析得出青山滑坡地质灾害发生的机理为:稳定性差的边坡在人类工程活动和强降雨条件下,使原有的力学平衡状态遭到破坏,导致滑坡灾害的发生。进行了灾害体稳定性评价,结果显示其稳定性较差,再次发生灾害的概率大,危险性大。
We have carried out the investigation of landslide characteristics and geological environment about the typical Qingshan landslide in Laoshan area, and analyzed the topography, hydrogeology, engineering geology and other conditions related to the occurrence of the landslide. Through comprehensive analysis of various factors, the mechanism of Qingshan landslide was concluded: under the condition of human engineering activity and heavy rainfall, the original mechanical balance of the slope with poor stability was destroyed, leading to landslide occurrence. The stability evaluation of the disaster body showed that its stability was poor, the probability of disaster occurrence was big again, and the risk was great.
