承插式预制拼装桥墩抗震性能研究综述

Study on Anti-seismic Property of Socketed Precast Assembled Bridge Pier

承插式连接构造是预制桥墩与承台之间的一种拼接方式,与灌浆套筒和灌浆波纹管等以钢筋为对接单元的拼接构造相比施工精度要求较低,与现浇湿接缝,预应力节段干接等构造相比现场作业少,是桥梁下部结构预制拼装的一种有力竞争方案。现从试验研究、理论研究和工程应用三个方面对承插式构造抗震性能研究进行综述,以促进该技术在国内预制拼装桥墩建设中的应用。

The socketed joint construction is a splicing method of precast bridge pier and base slab. Its construction accuracy is required lower by comparing with the grout sleeve and grout corrugated pipe taken the steel bar as the splicing unit of joint construction, and the field construction is little by comparing with the cast-in-situ wet joint and pre-stressed segment dry joint. It is a powerful competition scheme of precast assembly of bridge substructure. The article summarizes and studies the anti-seismic property of socketed construction from three aspects of test study, theoretical study and engineering application in order to promote the application of this technique in the construction of precast assembled bridge pier in China.
