摘要
就软土地基中高速公路桥台桩基变形规律的国内外研究现状进行分析,总结了目前包括软基中桥台桩基变 形规律的试验、有限元分析以及路堤下覆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。最后,结合 具体的桥梁桩基工程的有限元分析成果,进一步探讨了桥台桩基变形的基本规律,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 achievement reports, the current situation of the law of lateral deformation of the expressway piled bridge abutments constructed on soft clay is analyzed. This paper also summarized the 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. The existing problems and potential research topics in this field are finally put forward. A combined method of the finite element analysis and centrifuge model test to study the problems is proposed.
