Partially cable-stayed bridge tower beam pier consolidation system
The invention relates to the technical field of bridge engineering, in particular to a partial cable-stayed bridge tower beam pier consolidation system which comprises a bridge tower, a box girder No.0 block, a pier and a foundation from top to bottom. Lower tower columns of the longitudinal bridge are in a branch design, the lower tower columns are aligned with the box girder diaphragm plates, and the thickness of the diaphragm plates is the same as the longitudinal size of the lower tower columns. And the middle box chamber and the outer box chamber of the No.0 block are hollow box chambers. The piers are longitudinally aligned with the diaphragm plate and transversely aligned with the bottom of the box girder, and the pier top is not provided with a solid section. The longitudinal wall thickness of the pier top of the pier is longitudinally aligned with the transverse partition plate, and the longitudinal size is downwards reduced to a standard section by adopting a certain slope. According to the invention, the force transmission path of the existing partial cable-stayed bridge tower is changed, so that the vertical load borne by the bridge tower is directly transmitted to the pier through the diaphragm plate, and the force transmission path is clear; and the box chamber in the 0 # box girder is a hollow box chamber, and the pier top is not provided with a solid section, so that concrete cracking caused by non-uniform water thermalization of large-volume concrete pouring is avoided.
本发明涉及桥梁工程技术领域，尤其是涉及一种部分斜拉桥塔梁墩固结体系，所述体系自上而下包括桥塔、箱梁0号块、桥墩和基础。纵桥向下塔柱为分肢设计，下塔柱和箱梁横隔板对齐，横隔板厚度与下塔柱纵向尺寸相同。0号块中箱室和外箱室为空心箱室。桥墩纵向与横隔板对齐，横向与箱梁梁底对齐，墩顶不设实体段。桥墩墩顶纵向壁厚与横隔板纵向对齐，采用一定的斜率向下减小纵向尺寸至标准断面。本发明改变了既有的部分斜拉桥桥塔的传力路径，使桥塔承受的竖向荷载通过横隔板直接传递给桥墩，传力路径明确；0号块箱梁中箱室为空心箱室，且墩顶不设实体段，避免了大体积混凝土浇筑水热化不均匀导致混凝土开裂。
