雅砻江卡拉水电站工程区滑坡体一期基准网稳定性检验的实践

Stability test of benchmark phaseⅠ for landslide body of Kala hydropower station on Yalong river

对雅砻江卡拉水电站工程区滑坡体变形监测网的监测精度和在高山峡谷条件下的GNSS数据质量进行检验和评定,可为以后类似条件下的GNSS变形监测设计提供工程实践依据,对类似变形监测系统的建设具有借鉴意义。此外,对基准网稳定性情况、GNSS数据质量情况进行了检验分析。

In this paper, the monitoring accuracy of deformation monitoring network for landslide bodyof Kala hydropower station on Yalong river is studied and the quality of GNSS data under the conditionsof alpine canyon is evaluated, which provides engineering practice basis for GNSS deformation monitor-ing design under similar conditions. Moreover, the benchmark stability as well as the quality of GNSS da-ta are analyzed.
