| 摘 要： | 分析了南京市燕子矶中学实验楼后滑坡的影响因素,并使用瑞典条分法计算了滑坡体在自重和地震烈度7作用下的稳定性系数,计算结果表明:滑坡体在自重作用下处于基本稳定状态;滑坡体在地震烈度7作用下处于不稳定状态;在多种因素的影响下,滑坡体目前处于不稳定状态;滑动带为软可塑状粉质粘土层,最后通过经济评价,提出了采用削坡压脚联合挂网喷锚支护的治理方案。

| Abstract: | The paper analyzes the influential factors for the landslide behind the lab building of Yanziji Middle School in Nanjing,adopts the Sweden Slice Method to calculate the stability coefficient of the landsliding body under the effect of the gravity and the seismic intensity 7,and proves by the calculating result that the landslide body can remain the stable state under its gravity,while it can be in the unstable state under the seismic intensity 7,and it keeps in the unstable state with the influence of many factors,so the sliding zones are mainly soft plastic powder clay layer.Finally,through the economic evaluation,points out the treatment scheme by combining the slope cutting with pressing stand and the shotcrete rockbolt mesh support. |
