南昌地铁二号线隧道开挖风险性可拓学评价

Extension Assessment on the Risk of Excavation for Nanchang Metro Line 2

摘要:

地铁建设中始终面临着隧道开挖风险和毗邻建筑环境的风险，对其进行详细评价并找出主要影响风险源，对于控制工程风险、提高工程安全性和投资效益是地铁工程建设不可忽视的重要环节。应用可拓学方法，分别对南昌地铁二号线翠苑路-地铁大厦区间的隧道开挖风险和毗邻开挖区的建筑环境的风险进行评价，找出了最主要的风险影响因子，对同类工程建设具有借鉴意义。

Abstract:

There are always the risks for subway construction in tunnel excavation and adjacent building safety, a detailed risk assessment is necessary to find out the main risk source to control project risk, guarantee the engineering safety and improve the investment benefit. This paper introduces the risk assessment on Nanchang metro, the main risk factors are found out by extension theory, which can provide reference to similar engineering construction.
