深部位移监测在滑坡变形监测中的应用研究

基于巴东三中滑坡深部位移监测数据,分析该滑坡滑带所处深度,并结合桩孔内地质编录,将监测数据与实际观察的滑坡结构和滑动方向及滑带深度进行对比。结果表明,由于地表附近监测数据受外部影响较大,使得钻孔测斜数据可靠性降低,但测斜数据对于滑坡内部滑带土的鉴别与桩孔内发现滑带土深度一致。研究成果肯定了用钻孔测斜仪对滑坡变形进行监测是滑坡防治设计的重要手段之一。

Application of deep displacement monitoring in landslide deformation monitoring

Based on the landslide deep displacement monitoring data, we analyzed the depth of landslide sliding zone at the 3rd High School Landslide in Badong County, Hubei, and according to the geological catalog in pile-holes, we compared the monitoring data with the observational landslide structure, sliding direction and sliding zone depth.The results showed that the reliability of inclinometer data near the earth surface was weakened due to the influence of external factors, but the sliding soil identified by monitored data was consistent with the results of observed pile-hole.The research indicated that landslide deformation monitoring by borehole inclinometer is an important method for landslide controlling design.
