摘　　要：本文以某市域铁路的6 m×35 m无砟轨道预应力混凝土道岔连续梁作为实例,针对预应力连续箱梁的荷载试验展开了深入研究。借由静载试验与动载试验,对桥梁的强度、刚度、自振特性以及动力系数等予以测试分析,进而对其使用性能和承载能力做出了评估,同时为同类型的市域铁路桥梁的日常维护和运营管理提供了试验范例与参考依据。Taking the 6 m×35 m ballastless track prestressed concrete turnout continuous girder of a municipal railway as an example,this paper conducts in-depth research on the load test of prestressed continuous box girder.Through static load test and dynamic load test,it tests and analyzes the strength,stiffness,natural vibration characteristics and dynamic coefficient of bridges,and evaluates the service performance and bearing capacity of bridges.Meanwhile,it provides test examples and reference basis for the daily maintenance and operation management of the same type of municipal railway bridges.
