| 摘 要： | 为研究预应力混凝土连续箱梁桥的承载能力及实际工作状况,通过实际桥梁的静载试验,测得桥梁在各个工况下控制截面的应变、挠度随荷载增加能保持良好的线性关系,并判断实测残余变形与实测总变形比值小于0.2,同时采用桥梁专用有限元计算分析软件MIDAS/Civil建立试验跨模型,与静载试验实测数据进行对比分析,得到桥梁的应变校验系数和挠度校验系数,综合判断桥梁的承载能力能满足要求。

| Abstract: | For the research of prestressed concrete continuous box girder bridge carrying capacity and working condition,based on the actual bridge static load test,the thesis measures that strain and its deflection of bridge under the working condition of each control section can remain good linear relationships with the increase of load,determining that the measured residual deformation and the measured total deformation ratio is less than 0.2.Besides,adopting special finite element analysis software MIDAS/Civil build Bridges across model,compared with the measured data of the static load test and analysis,it gets the bridge strain calibration coefficient and deflection coefficient and comprehensively judges that the bearing capacity of the bridge would meet the requirements. |
