Abstract:

To monitor the stability of Xinhua Landslide in Dagangshan Reservoir area in real-time, the design of GNSS automatic monitoring network is carried out. The necessarily of the monitoring work is demonstrated by consideration of the geological condition and stability of the slope body. The automatic monitoring method is compared with the conventional method, and the pros and cons are analyzed. The composition frame of the automatic system and the function and connection of the sub-systems are introduced. Combining with the practical situation of    Xinhua Landslide, the datum mark test method, installation of the device, technical requirement of burial and technical index of deformation points monitoring are put forward.
