摘　　要：为了便于在现有堆石坝变形监测体系下对管道机器人监测系统的结果进行分析,并了解其在大坝沉降监测中的应用效果,介绍了一种管道机器人监测系统及大坝沉降计算方法。以贵州省夹岩水利枢纽工程为例,对管道机器人监测系统与传统水管式沉降仪的监测结果进行对比。结果表明:通过对管道机器人监测结果的解算,可得出坝体三维空间的沉降,便于在现有监测体系下对大坝变形情况进行统一分析。管道机器人与传统水管式沉降仪沉降监测结果的偏差较小,且沉降变化特征符合堆石坝沉降规律。管道机器人监测系统在堆石坝沉降监测中的应用具有可靠性,可为堆石坝安全评估提供依据。In order to facilitate the analysis of pipeline robotic monitoring system results under the existing deformation monitoring system for rockfill dams and to understand the effectiveness of its application in the monitoring of dam settlement,a pipeline robotic monitoring system and a method for calculating dam settlement were introduced.Taking Jiayan Water Conservancy Project of Guizhou Province as an example,the monitoring results of pipeline robot monitoring system were compared with that of traditional water pipe settlement meter.The results showed that the settlement of the dam body in three-dimensional space can be derived by solving the monitoring results of the pipeline robot,which facilitated the unified analysis of the dam deformation under the existing monitoring system.The deviation of the settlement monitoring results between the pipeline robot and the traditional water pipe settler was small,and the settlement variation characteristics were in line with the settlement law of the rockfill dam.The application of pipeline robot monitoring system in the settlement monitoring of the rockfill dam was reliable,which can provide a basis for the safety assessment of the rockfill dam.
