摘　　要：在人工填海形成的陆地上,由于海底地质复杂,岩溶发育,在这种地质条件下修建铁路桥梁的基础存在着难以预料的困难．针对弹性地基基础梁结构作为修建桥梁的基础形式,在地基基础梁、浇灌梁墩、桥梁建成后空载和承载下的基础梁钢筋受力和地基土压力进行了监测,对弹性地基基础梁的设计有重要的应用价值．There are lots of unexpected difficulties in constructing the foundation of a railway bridge on sea-filled land because of the complicated geological situation and topographical development of the seabed. With the elastic foundation beam being the basic construction form of a bridge, the detection of the bearing force of elastic foundation beam reinforcing steel bar and the bearing capacity of soil when the railway bridge is under load or not is illustrated, hence providing an important practical value to the design of the elastic foundation beams.
