摘　　要：基于浙江温台软土地区的地质条件,介绍常见跨度柔性桥台桩柱结构的作用效应,利用m法分析了各因素对桩基水平位移的影响,包括填料容重、桩直径、桩间距等,得到其变化趋势。结果表明,合理选取参数可避免桥台因水平位移较大而影响正常使用,保证工程质量和安全。Based on the geological conditions of soft soil area about Wenzhou-Taizhou in Zhejiang,action effects of flexible pile column in common-span bridge abutments are introduced.Besides,some effect factors on horizontal displacements in bridge abutments are analyzed by the means of m method,including filler bulk density,pile diameter,pile space and so on.The change rules are obtained.The results show that the more horizontal displacements of bridge abutments are avoided because parameters are reasonably chosen.Then,engineering quality and safety are ensured.
