预制拼装桥墩具有质量有保证、施工速度快、干扰小、环保等优点,是装配式桥梁进一步发展的方向。分别从试验研究、理论研究和实际工程应用三个方面进行归纳总结,对预制拼装桥墩的抗震性能、节段接头、后张预应力系统、桥墩断面、耗能装置和塑性铰区设置的研究结果和实桥应用进行了分析,进而对亟待研究的问题和进一步研究的方向进行了展望。
Prefabricated piers have the quality assurance, construction speed, small interference, environmental protection, etc., is the direction of the further development of the bridge assembly. Respectively from the experimental study, theoretical research and practical engineering application of three aspects are summarized, the prefabricated piers seismic performance, joints, post-tensioned prestressed systems, piers section, energy devices and plastic hinge zone set the results of the study And real bridge application analysis, and then the problems to be studied and the direction of further research are prospected.
