浙南地区典型滑坡稳定性评价及治理研究

Study on Stability Evaluation and Treatment of Typical Landslides in Southern Zhejiang

为查明滑坡的分布特征,评价滑坡的稳定性,采用工程地质调查、测绘、专项地质勘察等方法,查明了滑坡的成因,包括较厚较松散的土层;存在的软弱滑动面;及受强降雨影响渗入的地下水作用使土地体饱和、力学强度降低等因素。计算结果表明滑坡体处于临界稳定~不稳定状态,对滑坡体治理采取抗滑桩、截排水等措施,结合监测数据分析结果,达到有效的治理目标。

In order to find out the distribution characteristics of landslide and evaluate the stability of landslide,the causes of landslide,including thicker and loose soil layer,are found out by means of engineering geological survey,surveying and mapping and special geologi‐cal survey;existence of weak sliding surface;and the infiltration of groundwater affected by heavy rainfall makes the land saturated and the mechanical strength reduced.The calculation results show that the landslide mass is in a critical stable~unstable state.Anti slide pile,inter‐ception and drainage measures are taken for the treatment of the landslide mass,combined with the analysis results of monitoring data,so as to achieve the effective treatment goal.
