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.
