厦门地铁一号线某斜通道施工方案比选研究

为加快地铁施工进程，通常采取增加掌子面的方法来缩短工期。厦门地铁一号线城市广场站至塘边站区间采用增设一辅助斜通道与主隧道斜交施工方案，运用MIDAS/GTS数值模拟对斜通道的3种不同施工方案进行比选，得到最优方案；同时与现场监测数据相比较，验证斜通道与主隧道数值分析的准确性。

Study on the Comparison and Selection of the Construction Scheme of a Skew Channel in Xiamen Metro Line 1

In order to speed up the subway construction process, usually take the method of increasing the face to shorten the duration. To solve these problems, the scheme of adding an auxiliary oblique channel to the main tunnel is adopted in the urban square station to the pond station section of Xiamen metro line 1. In this paper, MIDAS/GTS numerical software is used to simulate and analyze three different construction schemes of oblique channel, and the optimum construction scheme is obtained by comparison and selection. At the same time, the numerical analysis of oblique channel and main tunnel is verified its accuracy compared with on-site monitoring data.
