港珠澳大桥沉管隧道管节预制厂选址研究

摘要

文章主要介绍了港珠澳大桥工程概况和沉管隧道管节预制厂的选址过程.港珠澳大桥沉管隧道管节预制厂可供选择的场地有广州南沙龙穴岛及伶仃洋桂山岛.根据沉管隧道预制厂的概况、生产流程,及其对港珠澳大桥项目的重要性,明确了选址需要考虑的因素；通过对比和分析南沙龙穴岛与伶仃洋桂山岛的地理位置及交通情况,以及地质与岩土工程方面存在的问题,本着工程安全为最重要因素的思路,选择了伶仃洋桂山岛作为港珠澳大桥沉管隧道管节预制厂厂址.%This paper introduces the selection process for the site of a segment prefabrication factory for the immersed tunnel of the Hong Kong—Zhuhai-Macao Bridge Project (HZM Bridge). The proposed sites for the prefabrica— tion factory were Longxue Island and Guishan Island. This paper explicates the factors used in site selection, including a survey of the prefabrication factory, work flow, and the importance to the HZM Bridge. Based on a comparison of their geographic positions, transportation conditions, and existing problems regarding geology and geotechnical engineering, Guishan Island was chosen as the site of the segment prefabrication factory.
