| 摘 要： | 装配式装配式施工已成为城市桥梁建设的发展趋势。然而，交通需求巨大的城市宽桥通常会有大量的下部结构承台。盖梁的长度往往大于25米，重量通常超过300吨。整体预制盖梁的运输条件受道路限制，整体吊装吨位过大。盖梁预制装配技术得到了广泛的重视和迅速的发展。本文对盖梁预制装配技术进行了分类，并介绍了典型的工程实例。总结了预制盖梁的性能研究现状，总结了盖梁预制装配技术存在的不足和改进方向。

| Abstract: | Prefabricated assembly construction has become a trend in urban bridge construction. However, urban wide bridges with high traffic demand usually have a large number of lower structure bent caps. The length of the bent caps is often greater than 25 m, and the weight is usually more than 300 t. The transportation conditions of the overall prefabricated bent caps are limited by roads, and the overall lifting tonnage is too large. The precast assembly technology of bent caps has been widely valued and developed rapidly. In this paper, the prefabricated assembly technology for bent caps is classified, and typical engineering cases are introduced. The performance research status of prefabricated bent caps is summarized, as are the existing shortcomings and improvement directions of prefabricated bent cap assembly technology |
