- 摘要:
- 全球定位系统用于滑坡变形监测目前在国内外逐渐展开。针对GPS用于四川省雅安峡口滑坡监测网的灵敏度进行了分析，并利用观测结果数据分析了滑坡的状态和滑动趋势。认为，GPS用于滑坡监测有其特殊性，能够满足其高精度要求；在网形设计时，应考虑灵敏度标准，有必要将变形分析和优化设计一体化；但要全面监测滑坡，最好能将地面监测和地下地质观测结合起来。
- Abstract:
- Based on the recent development of GPS application to landslides monitoring both at home and abroad, this article focuses on the analysis of the sensitivity of GPS monitoring network applied in landslides and its motion and tendency through the collected data in Yaan of Sichuan Province, and it is found that GPS application to landslides monitoring can surely meet its high precision.Furthermore, it is necessary to take sensitivity standards into consideration and put deformation analysis and optimization into a whole in network design.However, to have a full view of landslides monitoring, it would be best if ground monitoring can be correlated with underground geological survey.
