摘要

先进的GPS技术已成为结构健康监测的一种有效手段,但其测试精度始终受到多路径效应的干扰。本文首先介绍了结构健康监测的概念以及目前常用的监测方法,归纳了GPS对土木工程结构健康监测的独特优越性;然后,在简要介绍GPS监测原理和几个典型工程应用的基础上,重点论述了GPS监测中多路径效应产生的原因、消除策略以及国内外研究现状,最后对多路径效应需要进一步重点研究的问题进行了展望。

Abstract

The advanced GPS technology is becoming one of the most effective means for structural health monitoring (SHM), but the multipath effect has great influence on the monitor precision. In this paper, the concepts of SHM and common monitoring methods at present are introduced and the priorities of GPS in civil engineering are concluded. Then, based on the introduction to principles of GPS monitoring and its applications on some typical structures, the causes of multipath effect, the eliminating strategy and the research status home and abroad are mainly discussed. Finally, some key questions in view of the multipath effect for further study are proposed.
