摘　　要：结合有限元模型和实际工程荷载试验,研究桥梁在"危险截面"处的最大应力,并且结合高速公路桥梁行车特点,从桥梁横桥向和纵桥向两个方面考虑,得出高速公路桥梁永久观测系统应力测点优化布置结果,从有限的传感器中得到较为精确应力信息,结果实用可靠,为以后实际桥梁布设应力观测点提供了参考和依据。Combined with the finite element model and the actual engineering load test, the maximum stress of bridge in the dangerous section is studied.According to the highway bridge traffic characteristics,from the transverse and longitudinal direction of the bridge aspects, the optimal layout of thehighway bridge permanent observation system is obtained.And more accurate stress information is obtained from the limited sensor.The results are practical and reliable, which provide reference and basis for the observation points of the actual bridge.
