广州市南沙某河流岸边软基上修建的桥梁,因堤岸存在高差和岸基软土固结作用造成软土向河床侧流动,加之在靠近桥梁基础岸边侧进行沿岸道路的施工堆载及施工机械作用,更加剧了软土的侧向变形,造成桥基向河床侧发生了380 mm的水平位移。本文结合桥基偏位的监测数据,采用Midas/Civil软件对该桥基的受力性能进行分析,确定斜桩的承载能力,最后提出对桥梁基础的处治措施。
廣州市南沙某河流岸邊軟基上脩建的橋樑,因隄岸存在高差和岸基軟土固結作用造成軟土嚮河床側流動,加之在靠近橋樑基礎岸邊側進行沿岸道路的施工堆載及施工機械作用,更加劇瞭軟土的側嚮變形,造成橋基嚮河床側髮生瞭380 mm的水平位移。本文結閤橋基偏位的鑑測數據,採用Midas/Civil軟件對該橋基的受力性能進行分析,確定斜樁的承載能力,最後提齣對橋樑基礎的處治措施。

Because of the height difference and soft soil consolidation of the embankment,the soft soil would be caused to flow to the side of one river in Guangzhou,over which a bridge is built,and because of the heaped loads and mechanical action in construction,the lateral deformation of the soft soil would become more serious to cause the bridge foundation to have horizontal displacement to the river side about 380 mm.Here,combining with the monitoring data of the offset displacement,the force performance of the bridge foundation is analyzed by using Midas/Civil software,and the carrying capacity of the inclined pile is confirmed,then the treatment measures for maintaining the bridge foundation are proposed.
