摘要
根据国内外文献资料,主要就软土地基上桥头路基填筑对桥台桩的侧向影响研究现状进行分析,总结了目前包括软基上桥头路基填筑对桥台桩基影响的试验、有限元分析以及路堤下卧软土侧向变形引起的桩身土压力计算等诸多方面的研究成果,简要论述了存在的问题和今后的研究方向,并建议采用有限元分析和离心模型试验相结合的方法来研究这些问题。
According to geotechnical literatures,the current research situation of embankment lateral effects on the piled bridge abutments on soft clay is analyzed. The field observation results and centrifuge model tests of piled bridge abutments on soft ground,finite element analysis of the soil-pile interaction and various computation techniques of the lateral earth pressure acting on the piles from horizontal soil movements are summarized. The existing problems and potential research topics in this field are put forward. A combined method of the finite element analysis and centrifuge model test is proposed.
