滑坡变形立体监测网建设

Building of three-dimensional monitoring network of landslide deformation

论文简要介绍了滑坡监测工作内容和监测方法，对现有技术方法在实际工作中的优缺点进行了简要评述。认为在滑坡稳定性监测工作中应该建立全方位、多种手段的立体监测网，仅仅运用某一种或者某一单方面的监测方法是不行的，是片面的，无法准确了解滑坡的动态。所说的立体监测网既有水平位移监测又有垂直位移监测，既有滑坡地表表层变形监测又有滑体深部变形监测，既有专业监测又有群测群防体系。同时监测有可能准确地掌握使滑坡失稳的各种因素（自然因素和人为因素）。因此建议在滑坡监测中建立全方位、多种手段的立体监测网，并提出了立体监测网建设的主要内容。

This paper summarizes the contents and methods of landslide monitoring. Merits and defects of current methods are reviewed. It is agreed that mahiple and three-dimensional monitoring network should be built in the stability monitoring of landslide. It is not enough to use only one kind of monitoring method because the dynamic of landslide cannot be known accurately. The three-dimensional monitoring network includes monitoring of horizontal and vertical displacement, deformation of landslide both on surface and subsurface. It is also should be a combined system for both professionals and lagmen. At the same time, the three-dimensional monitoring network can monitor every factor causing slope failure （including natural and man-made factors）. So, the author suggests use of three-dimensional monitoring network in stability monitoring of landslide, and its main components.
