摘　　要：津滨轻轨工程近 40km采用高架桥梁 ,选定合理的桥梁结构型式至关重要。根据工程及现场的实际情况 ,明确桥型选择原则 ,同时提出 7种桥型结构 ,分别论述其各自的技术特点 ;并结合地基基础实际情况 ,全面进行技术经济比较 。Viaduct covers nearly 40km of the total length of Jinbin Light Rail, therefore, selection of appropriate bridge type is of vital importance. Principles for selection of bridge type were determined according to project condition and actual situation of construction site. Seven bridge types were presented, and their respective technical characteristics were introduced. All round technical and economic comparison was performed based on geological conditions, and recommended bridge type was put forward.
