摘要
深部位移监测是滑坡安全稳定监测的重要技术手段之一。由于滑坡滑动方向与测斜管方位角可能存在偏差、数据分析方法片面等原因,从而导致工程师对滑坡的变形失稳特征的认识和判断出现错误,影响滑坡防治措施的实施。提出滑坡深部位移监测孔合位移的计算方法,并且采用基于极点等密度图和倾向玫瑰花图的滑坡滑动方向方位角计算方法,有效确定了滑动方向,简化了滑坡深部位移数据分析过程。通过工程监测实例,验证了该方法的适用性。该文提出的滑坡深部位移监测孔合位移计算与分析方法对深部位移监测和滑坡防治设计提供了参考。
Deep displacement monitoring is one of the important technical means of landslide safety and stability monitoring.Because of the deviation between the sliding direction of landslide and the azimuth angle of inclinometer pipe,as well as the one-sided data analysis method,engineers may have a wrong understanding and judgment of the deformation and instability characteristics of landslide,which may affect the implementation of landslide control measures.In this paper,the calculation method of the hole combined displacement of the deep displacement monitoring of the landslide is proposed,and the calculation method of the azimuth angle of the sliding direction based on the pole isometric diagram and the tendency rose diagram is used to effectively determine the sliding direction and simplify the data analysis process of the deep displacement of the landslide.The applicability of this method is verified by an engineering monitoring example.In this paper,the calculation and analysis method of the hole combined displacement for the deep displacement monitoring of landslide is proposed,which provide some reference for the deep displacement monitoring and landslide prevention design.
