地铁浅埋暗挖大断面隧道近距穿越楼房施工方法选择探讨
首发时间:2009-02-04
摘要:在隧道穿越既有房屋的施工中,核心目标是保证既有房屋的安全使用,主动地选择施工方法才是从根本上减小施工对环境影响的有效途径,本文首先对大量工程实例做了统计分析,并采用定性手段对常见的多种施工工法做了初步比较,而后重点对适合本文所提到工程实例的可能的两种工法做了对比,采用数值模拟手段,较为详细地分析对环境的影响程度,以期寻找一种特定工程形态下的理想隧道穿越施工方法。

Study on selection of construction method building large section tunnel using mining method on adjacent building
Abstract:During constructing the tunnel through the existing building, the core goal is to ensure the safety of existing building and the effective way fundamentally reducing the environmental impact of construction is to take the initiative to choose the construction method. This article firstly has done a statistical analysis for a large number of projects and has done a preliminarily qualitative comparison with a variety of common construction method, and then has done a comparison mainly with two possible methods referred in this article. Finally, by the numerical simulation tool, analyze more detailedly the impact to environment, so as to looking for the ideal construction method in a specific project.
Keywords: Metro Mining Method Large Section Tunnel Construction Method
