摘　　要：结合哈大铁路客运专线某900 t箱梁预制梁场的工程概况及工程地质勘探资料,对已投入使用的存梁台座进行沉降计算研究,分析台座的工作机理,通过比较不同的计算方法及其计算结果,并与实测沉降数据对比,找到了适合台座沉降计算的方法及参数取值,获得了存梁台座支点沉降及不均匀沉降的发展规律,为台座设计和沉降控制提供指导和依据。Combined with the engineering situation of 900 t precast box beam field of Harbin-Dalian passenger dedicated line and geological exploration data,the settlement of deposit beam pedestals that have been put into operation is studied and the working mechanism of pedestal is analyzed.By comparing different calculation results from different methods with the settlement data,the appropriate method of settlement calculation and parameters are determined,and the developmental law of pedestal support settlement and uneven settlement is obtained,which can provide guidance and theoretical basis for pedestal design and settlement control.
