ALGA新型支座在京津客专连续梁中的应用

On the Application of the New-type ALGA Bearing Supports to the Continuous Girder of the Beijing-Tianjin Passengers-Oriented Railway

在介绍ALGA系列支座结构构造的特点、力学性能及自升式无级调高原理的基础上,全面阐述AL-GA系列支座安装技术、注意事项及在京津城际铁路现浇连续梁中的应用效果。这对易产生不均匀沉降的软土地区无碴轨道桥梁和需要调整支座反力桥梁支座的选用及施工具有一定参考价值。

Upon the basis of introducing the structural characteristics and mechanical performance of the ALGA series of hearing supports, and the principle of the self-lifting stepless elevating, the fixing techniques for ALGA series of bearing supports, points for attention, and the effects of the application of the bearing supports to the continuous cast-in-place girder of the Beijing-Tianjin Inter-municipal Railway are presented in an all-round way in the paper, which may be of certain referential value for the correct choice and construction of non-ballast track bridges in soft soil areas, which are liable to uneven settlement, and where bridge bearing supports need to be used whose counterforce has to be adjusted.
