摘要
在对藤州中学滑坡地质环境综合调查的基础上,分析了该学校1#、2#、3#滑坡的形态特征及分布范围,用改进传递系数法和Morgenstern-Price法分别对这3组滑坡的稳定性进行分析,最后对滑坡的稳定性进行了综合评价。结果表明:(1)滑坡区由于1#、3#滑坡的滑动牵引2#滑坡滑动,形成了独特的牵引式滑坡。(2)2#滑坡在枯水季节基本处于稳定状态,在常水、丰水季节处于欠稳定状态;1#、3#滑坡在枯水、常水和丰水季节均处于稳定状态。
On the basis of comprehensive geological environment investigations,this article studies morphological characteristics,distribution and stability of landslide 1,landslide 2,and landslide 3 at the Teng high school.Transfer coefficient method and Morgenstern-Price method are used in calculation of stability of the landslides.Finally there is a comprehensive evaluation on the stability of the landslides.The result shows：（1）Landslide area that happened in landslide 1,landslide 2,and landslide 3 slid and resulted in the unique retrogressive landslide.（2） landslide 2 is basically stable in dry level and under-stable in normal level and flood level;landslide 1 and landslide 3 are stable under any condition.
