大岗山库区新华滑坡GNSS自动化监测网设计

为能实时监测大岗山水电站库区新华滑坡的稳定情况，开展了全球导航卫星系统（GNSS）自动化监测系统的设计工作。首先结合该滑坡体地质条件及稳定性情况，论证了实施监测的必要性。将常规监测方法和GNSS自动化监测方法进行比较，分析了各自的优缺点，介绍了自动化系统的组成构架以及各子系统的功能与联系。提出了基准点检验的方法，仪器安装、埋设的技术要求和变形测点的观测技术指标。

Design of GNSS automatic monitoring network of Xinhua Landslide in Dagangshan Reservoir area

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.
