南京地铁三联拱区段施工方案计算分析

Calculation and Analysis of the Construction Program in Triple-arch Section Nanjing Subway

根据南京市轨道交通1号线南延安德门～宁丹路区间隧道的工程概况,主要对上方有5层人造花总厂办公楼的三连拱区段进行施工方案选择,并对该方案进行数值模拟,从地表沉降、支护结构轴力、弯矩等方面进行分析,分析结果表明该方案是可行的,为今后类似工程的施工提供指导。

Based on the project profiles of the tunnel in Nanjing orbit traffic line 1 South Yah＇an road to Ningdan road, the article mainly processes to choose the construction program to three arch sections, on which there is a 5-factory office building. The paper carries on the numerical simulation to the construction program and analyses from surface subsidence, axial force of supporting structure, bending moment and other aspects. The results show that the program is feasible. The article provides guidance to the future construction of similar projects.
