摘要/Abstract

摘要：

对雅砻江上某滑坡体采用GNSS变形监测系统的设备选型、监测点和基准站布置、系统组成、通信方式及系统技术要求等进行了分析总结。在借鉴国内同类工程应用GNSS系统的经验和相关研究成果的基础上，本滑坡体GNSS系统采用了三星六频及以上数据混合解算、静态相对定位法等，使滑坡体上监测点和基准站在高度截止角偏大、多路径效应干扰等不利条件下，实现了满足滑坡体需求的监测精度和观测频次，可及时掌握滑坡体的变形情况及发展趋势。

Abstract:

This study analyzes and summarizes the equipment selection, layout of monitoring points and reference stations, system configuration, communication scheme, and technical specifications of the GNSS deformation monitoring system deployed for a landslide along the Yalong River. Drawing on experience of GNSS applications in domestic projects and relevant study findings, the GNSS system deployed on this landslide mass employs a hybrid solution using three-satellite six-frequency and higher data, as well as the static relative positioning method. This enables the monitoring points and reference stations on the landslide to achieve monitoring accuracy and frequency required for the landslide, even under adverse conditions such as a large cutoff elevation angle and multipath interference. As a result, the deformation status and development trends of the landslide mass can be monitored in a timely manner.

Key words: high-precision GNSS, monitoring cloud platform, multipath effect, field testing, data processing
