通过对国内某跨海公铁两用大桥主桥梁墩固结处的缩尺模型试验研究，得到单箱双室混凝土梁在各种荷载下的应力分布图，并将试验结果与理论分析值进行比较，为设计施工提供了依据．
Through the scaling model test research on the consolidation of the main bridge piers of a cross-sea railway bridge in China, the stress distribution of the single-beam double-chamber concrete beams under various loads is obtained and the experimental results are compared with the theoretical analysis values Comparison provides the basis for the design and construction.
