| 摘 要： | 运用FLAC2D软件,在没有考虑施工缺陷影响的前提下,针对乌鞘岭隧道志留系板岩夹千枚岩地段扩挖施工引起的群洞效应进行数值模拟,通过对比分析在左线正洞扩挖前后,围岩塑性区分布、位移以及隧道支护结构中的内力,进行了影响程度的综合评价,可为类似工程施工提供参考。

| Abstract: | The Silurian section with schist and phyllite was encountered during the construction of Wushaoling Tunnel. Interactions between tunnels in these sections because of enlarging and excavation are simulated by use of FLAC2D in this paper, thoughtless consideration of the defect effect under construction. After through comparison of the distribution of plastic region, the displacement of the surrounding rock and the internal forces of the supporting structures in tunnel, overall evaluation of the interactions is obtained. This can be reference to the construction of similar project |
