综合管廊工程设计中的经济比选

Economic Comparison and Selection in Design of Utility Tunnel Engineering

摘要:

在综合管廊工程设计中，为使方案同时满足功能需求、结构安全及经济适用的要求，通常需对多个方案进行比选，且最终方案需满足结构安全、功能适配、经济合理等多维度要求。方案比选内容主要集中于管廊布置方案、围护结构形式及基坑地基加固等环节。以上海某综合管廊工程为研究对象，针对上述三个方面展开深入分析与研究，通过量化计算获取可靠数据，旨在为设计人员的方案比选工作提供可参考的经济指标，从而在确保工程功能需求与结构安全的前提下，实现项目经济适用性的最优化。

Abstract:

In the design of utility tunnel projects, to make the scheme simultaneously meet the requirements of functional needs, structural safety and economic applicability, it is usually necessary to compare multiple schemes. The final scheme must satisfy multi-dimensional requirements such as structural safety, functional adaptation and economic rationality. The content of scheme comparison mainly focuses on the layout scheme of utility tunnel, the form of the enclosure structure, the reinforcement of foundation pit foundation, and the other links. Taking a utility tunnel project in Shanghai as the research object, the in-depth analysis and research on the above three aspects are conducted, and the reliable data are obtained through quantitative calculation. Its aim is to provide reference in terms of economic indicators for designers in scheme comparison to realize the optimization of economic applicability of the project on the premise of ensuring the functional needs and structural safety of the project.
