摘要
预制拼装桥墩由于其良好的力学性能和施工优势,在国外曾有不少工程实践和研究。但是国内针对节段拼装桥墩抗震性能的研究还是空白,明显滞后于工程实践,不能满足工程建设的需要。因此,本文对节段拼装桥墩的应用、接缝分类及其力学特性、试验研究和理论研究方面的情况进行了总结,并指出了存在问题和进一步研究的方向。
Precast concrete segmental bridge piers have been studied and designed at abroad for excellent mechanical characteristics and practical advantages in construction. While few works have been done for the seismic performanee of them at home. The research fails behind the application and could not satisfy the demands of application. The main aspects of seismic research on segmental bridge columns are reviewed, including the application at home, the kinds of joints and their mechanical behavior, and the experimental and analytical research. Some recommendations for future research on seismic performance of the precast concrete segmental system are offered.
