摘　　要：预制梁桥的主梁通常采用架桥机或吊车架设,当跨越河道桥梁上方受低空高压线限制时,上述架设方法均不适用。本文采用架桥机与地面运输系统相结合的方式,能有效解决条件受限状况下的架梁问题,可为同类工程提供参考。Bridge erecting machines and cranes are generally used for installing the main beams of prefabricated bridges,however,these methods are not applicable for bridges that cross rivers and are restricted by low-altitude high-voltage lines.This paper combined the bridge erecting machine with the ground transportation system,which can effectively solve the difficulty of erecting girders under restrictions,providing a reference for similar engineering.
