珠江三角洲水资源配置工程输水盾构隧洞形式优化设计分析

Optimal Design Analysis of Water Conveyance Shield Tunnel Form for Water Resources Allocation Project in the Pearl River Delta

盾构隧洞在输水方面具有显著优势,如限制少、规避不良地质、成本节约等,故被相关领域广泛关注。本文采用案例研究法,选取珠江三角洲水资源配置工程项目为实例进行针对性分析,在明确工程概况基础上,对水资源配置工程中的输水盾构隧洞形式进行对比选择,并以因地制宜为原则进行分析,提出了输水盾构隧洞形式优化方案,通过对比优化前后的差异,最终确认了优化设计方案的可行性,以供参考借鉴。

Shield tunneling has significant advantages in water transportation,such as fewer restrictions,avoidance of adverse geological conditions,and cost savings,which have attracted widespread attention in related fields.In this paper,the case study method is used to select the the Pearl River Delta Water Resources Allocation Project as an example for targeted analysis.On the basis of clarifying the general situation of the project,the form of the water transmission shield tunnel in the water resources allocation project is compared and selected.Based on the principle of adjusting measures to local conditions,the analysis is carried out,and the optimization scheme of the form of the water transmission shield tunnel is proposed.By comparing the differences before and after the optimization,the feasibility of the optimization design scheme is finally confirmed for reference.
