1、I 摘要摘要 本论文分析和评估城市地下工程施工新技术及工程应用,主要包括城市地下工程施 工新技术的现状及发展趋势、城市地下工程施工新技术的应用条件及关键技术、地下工 程施工新技术的应用案例分析与总结三个方面。 本文主要论述了地下工程施工的关键技术,如新奥法、盾构法、浅埋暗挖法等方法。 使用盾构法、新奥法施工作为一种施工理念已贯穿于各种施工技术之中。而地下工程施 工新技术的应用案例中,本论文以上海地铁为例,分别为上海地铁 1 号线为新奥法施工 的案例,2 号线以盾构法施工的案例进行了分析。 施工机械方面,隧道掘进机(TBM)得到了优先发展。在隧洞快速开挖中,优先采 用隧道掘进机已成为国际发展趋势
2、。近代掘进机的最大特点是广泛使用电子、信息技术 对全部作业进行制导和监控,使掘进过程始终处于最佳状态。隧道掘进机是利用回转刀 具开挖,同时破碎洞内围岩及掘进,形成整个隧道断面的一种新型、先进的隧道施工机 械。 城市环保方面的发展趋势, 本论文在减少地面沉降、 降低噪音、 减少振动等方面 (即 地下工程施工对城市繁华街道的干扰如何减至最小)进行分析、综合。 关键词:关键词:盾构法,新奥法,掘进机,上海地铁 II Abstract This thesis analysis and assessment of urban underground engineering construction of

Modern tunneling machine biggest characteristic is the widely use of electronic information technology, for all operation guidance and monitoring, so that the development process has always been in the best condition. Tunnel boring machine is the use of rotary cutting tool and broken surrounding rock excavation, tun
