路基堆载下软土侧移对桥台桩基影响研究综述

摘要

根据国内外文献,综述现有路基堆载下软土侧向位移对桥台桩基影响的研究概况,着重介绍了桥台桩基在路基堆栽下的变形规律试验、路堤下覆软土侧移对桩身的极限侧压力计算方法以及桩土相互作用计算方法等的研究成果,简要论述了存在的问题及今后进一步研究的方向.%According to internal and external literatures, the current research situation of the influence of piled bridge abutment by soft soil lateral displacement under heaped loads is summarized.The results of deformation test of piled bridge abutment under heaped loads, the calculation of ultimate lateral pressure of pile body due to soft soil lateral displacement, and the calculation of pile-soil interaction are introduced emphatically.The existing problems and further I research topics are proposed.
