港珠澳大桥某预制场临时码头工程提梁门架设计

Design of girder upgrading gantry for a temporary dock project of HZMB

大型临时工程受力构件主要采取钢结构形式,便于重复利用。由于大型临时工程承担的荷载一般较大,结构耗费钢材较多,因此,如何在保证结构安全的前提下尽可能减少钢材用量是摆在设计人员面前的一道难题。本文介绍港珠澳大桥香港接线高架桥工程预制场临时码头工程提梁门架的设计思路及特点。通过对不同结构形式进行比选,并充分利用现场已有材料,确定合理的门架结构形式。

The current domestic large temporary works mainly adopt steel structures load on the large temporary works become heavier, the steel structures would cost challenge to ensure the safety of the structure and reduce steel consumption as far as the design of the girder upgrading and making full use of the existing possib gantry for a temporary dock project of HZMB. Adopting materials, we finally determine the reasonable structure for the recycled use. As more. Therefore, it is a le. This article describes different structure forms of the gantry.
