摘　　要：拱作为一种传统的结构型式,始终是桥梁的主要比选方案之一。在软土地基上建造拱桥首先要解决拱脚处的水平推力以及软土地基的流变问题。通过昆山正阳桥的设计,从结构体系和下部结构基础形式的比选,对软土地基上拱桥的设计作了初步的探索,以期为今后相关的工程提供参考。Arch bridge is an important type in plane phase for its beautiful form. To solve horizontal thrust at arch feet and rheological change in soft soil is the first problem for arch bridge construction on soft soil ground. This paper discusses how to design main structure and foundation forms for arch bridges on soft soil ground by employing an example, ZhengYang Bridge, in Kun Shah, in order to provide references for similar projects.
