深圳妈湾跨海通道总体方案设计关键技术研究

Research on Key Technologies of Overall Scheme Design for Mawan Cross-sea Channel

以深圳妈湾跨海通道工程为例,详细介绍了城市货运交通跨海隧道总体方案设计的关键技术。从项目本身特点出发,总结出跨海隧道总体方案设计过程中需要重点关注的几个关键点,包括标准的确定、跨海段工法选择、道路线形设计、进出口匝道设计、立交节点设计、防灾救援体系等。通过以上关键技术点的分析,从总体上把控跨海隧道总体方案设计,以期获得与工法方案、地质条件等很好结合的隧道设计方案,为同类工程提供借鉴。

Taking Mawan Cross-sea Channel Project as an example, this paper introduces the key technologies of the overall scheme design for the urban freight transportation cross-sea tunnel in detail.Starting from the characteristics of the project itself, this paper summarizes several key points to focus on in the design process of the overall scheme for the cross-sea tunnel including the determination of standards, the selection of construction methods for the cross-sea section, the design of road alignment, the design of the ramps at the entrance and exit, the design of interchange nodes, and the system of disaster prevention and rescue. Through the analysis of the above key technical points, the overall scheme design of the cross-sea tunnel is controlled in order to achieve a tunnel design scheme combined with the construction method scheme and geological conditions well, which can provide a reference for the similar projects.
