装配式综合管廊施工社会经济效益综合分析

Comprehensive Analysis of Social and Economic Benefits of Fabricated Utility Tunnel Construction

摘要: 装配式综合管廊采用与现浇式综合管廊不同的生产模式，其技术要点、施工技术、施工管理与组织等方面均有显著不同，导致在建设过程中所发生的费用类型与数量也有很大的不同。本文对其社会经济效益进行了全面的分析，提出综合管廊社会经济效益应分为直接建设费用和间接影响费用两方面进行核算，前者主要包括结构建设成本和基坑开挖与支护成本，后者主要包括时间延误成本、额外燃油消耗成本、商业运营成本、污染物排放成本、绿色施工管理成本以及其他成本等；并进一步对相关间接影响成本提出了计算方法；最后以上海2015年交通出行相关统计数据为例，进行了间接影响费用的相关计算，可发现考虑间接影响成本后，装配式综合管廊具有显著的经济优势。

Abstract: The fabricated utility tunnel adopts a different production mode from that of a cast-in-site utility tunnel. The technical essentials, construction technology, construction management and organi-zation are all significantly different. As a result, types and amounts of expenses in the construction process are also quite different. This paper makes a comprehensive analysis of its social and eco-nomic benefits, and puts forward that the social and economic benefits of utility tunnel should be divided into two aspects: direct construction costs and indirect impact costs. The former mainly includes construction costs and the excavation and support costs of foundation pits. The latter mainly includes time delay costs, additional fuel consumption costs, commercial operating costs, pollutant emission costs, green construction management costs and other costs; it further proposes a calculation method for the related indirect impact costs; finally, it uses Shanghai's 2015 traffic travel statistics as an example to carry out the indirect impact costs, and it can be found that after considering the indirect costs, the fabricated utility tunnel has significant economic advantages.
