摘　　要：为解决目前大坝结构瞬态形变状况难以预测、形变监测准确率不高的问题,采用北斗/全球导航卫星系统技术对已有监测系统进行优化,以期提高系统的监测准确率和数据传输处理速度。将优化前后的系统进行对比,结果显示,优化后的系统在自动化程度、形变预测准确度、通信稳定性和监测精度四个方面显著优于前系统,且优化后的系统传输和处理所需时间缩短了11.7 s。To solve the problems that the transient deformation of dam structure is difficult to predict and the accuracy of deformation monitoring is not high,Beidou/global navigation satellite system technology is used to optimize the existing monitoring system,aiming to improve the monitoring accuracy as well as data transmission and processing speed of the system.The comparison results show that the optimized system is significantly better than the former in aspects such as degree of automation,deformation prediction accuracy,communication stability and monitoring accuracy,and the transmission and processing time of the optimized system is shortened by 11.7 s.
