多种监测手段在滑坡变形中的组合应用

Multi-monitoring methods joint application in landslide deformation monitoring

针对多种监测手段在滑坡中如何经济并高效的使用问题,该文结合高精度智能全站仪、地表位移计及全球卫星导航系统-实时动态差分(GNSS-RTK)3种监测技术的各自特点,基于实际滑坡变形监测应用,提出不同滑坡阶段应采取多种手段组合监测,实现经济、高效的滑坡变形状态识别并进行安全预警。结果显示:滑坡稳定阶段,全站仪可作为主要监测手段进行周期性监测;滑坡加速阶段,增加GNSS-RTK和位移计两种实时监测技术,可以更灵活、高效地实现滑坡体垮塌的快速捕捉,进行安全预警。

Aiming at the economic and efficient use of various monitoring methods in landslides,the paper proposed a proper joint solution that could be conducted to effectively detect and warn the dangerous of landslides at different stages of landslides at the lowest cost based on an analyzation of the characters of high precision total station,extensometer,as well as GNSS-RTK(Real-Time Kinematic with Global Navigation Satellite System).The results showed that the total station could be mainly used to monitoring the landslide during stabilization phase;in the acceleration phase of landslide,the real-time methods of extensometer and GNSS-RTK,which could be more flexible and efficient,should be additionally needed to realize the collapse of landslide with a safety warning.
