摘要
以偏压连拱隧道为基本模型,对8种不同的进洞开挖方式进行模拟计算,获得了偏压连拱隧道在不同开挖顺序施工时各阶段围岩的边坡沉降、应力应变状态变化情况;通过分析比较,得到了偏压连拱隧道合理的进洞方式,为今后类似条件下连拱隧道的进洞设计提供参考。
In order to study the settlement of slope and the variety of the stress and strain, numerical simulation is carried out by eight different excavating sequences on the basis of the model of slope twin tunnel. And a rational construction mode is gained through the comparison between the eight different excavating sequences. The conclusion can be consulted for the future project.
