大拱形式连拱隧道是不同于典型连拱隧道的一种结构形式。通过模拟分析浅埋偏压条件下大拱形式连拱隧道在不同开挖工序下各部分结构的受力性状,得出相对合理的开挖工序。
Large arched multi-arch tunnel is different from the typical multi-arch tunnel structure. By simulating and analyzing the mechanical behaviors of the arch structures with different arching under different conditions of shallow excavation, the reasonable excavation procedure is obtained.
