港珠澳大桥斜拉桥监理特点

Supervision features of cable-stayed bridge in the HZMB

针对斜拉桥的特点,按照规定的程序和步骤进行施工,并分析桩基、承台、墩身、混凝土索塔、钢索塔、钢箱梁、支座、伸缩缝、减振器、阻尼器等施工监理控制重点,在施工过程中进行严密监控,使成桥线型和内力满足设计要求。

According to the characteristics of cable-stayed bridges, in accordance with the procedures and steps required for the construction, this paper analyzes the construction supervision control points of the pile foundation, pile caps, piers, con- crete towers, steel towers, steel box girders, bearings, expansion joints, shock absorbers and dampers, closely monitors the construction process, so that the linetype and inner force of the finished bridge can meet the design requirements.
