| 摘 要： | 三峡库区张桓侯庙东侧滑坡为一大型土质滑坡。为了掌握滑坡的变形状态,对滑坡实施应急动态监测,采用了地表位移、地表沉降、深部位移、地下水位、降雨量及泉流量监测等手段,确定了滑坡的变形范围、主滑方向、滑面深度等基本要素及内部、外部变形特征,通过对监测成果的综合分析将滑坡分为强变形区与弱变形区,确认滑坡性质总体上为推移式,右侧前缘具有牵引式的性质。判断滑坡在监测期间处于匀速变形阶段,降雨是影响滑坡稳定性的主要因素,起到了加速滑面形成的作用。利用监测成果修正了滑面形态,反演滑带参数。建议对滑坡的防治加强地表排水,切忌对强变形区前缘进行开挖。 |

| Abstract: | The Zhanghuanhou Temple landslide is a large-sized soil landslide.In order to learn the status of its stabilization,the emergency dynamic monitoring system was applied to the landslide,in which the surface deformation,internal deformation,groundwater level,rainfall monitoring methods were adopted to affirm the deform range,main slide direction,location of slide surface,deformation behavior,etc.Through comprehensive analysis of the monitoring data,the landslide was divided into two subareas: acutely deformed area and relatively faintly deformed area.The landslide belongs to a thrust load causing the landslide as a whole,the toe of the right side was deformed in retrogressive mechanism.During the monitoring period the landslide belongs to the constant deformation stage.Rainfall is the main influence factor,which accelerates the formation of slide surface.By making full use of monitoring results the slide surface was modified and the slide surface parameters were inverted.Beneficial proposal was put forwad for the following comprehensive management engineering design and construction.The drainage engineering must be adopted and to avoid the excavation in the toe of the acutely deformed area. |
