摘要

沉管法是20世纪初发展起来的一种专门修建水下隧道的工法，适用条件较为苛刻，随着工程技术的发展，其适应性越来越强。继丹麦—瑞典的厄勒松海峡沉管隧道和韩国釜山—巨济沉管隧道修建之后，我国正在珠江口伶仃洋30万 t主航道下修建港珠澳大桥沉管隧道，借鉴了国外技术与国内施工经验，自主创新，结合工程项目特点，在地质勘察、结构分析、耐久性设计、管节预制、地基与基础处理等方面发展了一些新技术，并对这些新技术进行了探讨和总结。

Abstract

Immersed tube method is a special construction method for underwater tunnel developed in the early 20th century. Its application conditions are rigorous, but its adaptability becomes more and more strong. After the Oresund Strait immersed tunnel from Denmark to Sweden and the immersed tunnel from Busan to Geoje in Korea, HongkongZhuhaiMacao Bridge (HZMB) Immersed Tunnel in China is under construction below the main channel of Lingdingyang of Pearl River Estuary. The engineers are overcoming difficulties in the process of practice, with independent innovation and learning from foreign and domestic technology and construction experience. Some new technologies in terms of geological survey, structural analysis, durability design, tube prefabrication and foundation treatment, etc. are developed on the basis of the project characteristics. This paper tries to discuss and summarize these new technologies.

Key words： HongkongZhuhaiMacao Bridge; immersed tunnel; tube element installation; geological prospecting
