摘要
对装配式高架桥盖梁轻型化进行了研究,提出了预制盖梁轻型化的几个研究方向,重点推荐优化截面形式以达到盖梁轻型化,包括根据受力需要选择T截面或空心截面;并通过理论计算验证了研究方向的可行性,为后续解决桥梁预制拼装中盖梁体量过大,无法整体预制的难题提供了理论基础。
The lightweight of fabricated viaduct bent cap is studied.Several study directions for the lightweight of fabricated viaduct bent cap are proposed.It is specially recommended to optimize the cross-section form for the lightweight of bent cap,including the selection of the T-section or hollow section according to the force requirements.And the feasibility of the study direction is verified through theoretical calculations,which provides a theoretical basis for the subsequent solution of the problems that the volume of bent cap is too large and the overall prefabrication is difficult.
