Optimal analysis of mid-board of shallow double-arch tunnels under unsymmetrical pressure 浅埋偏压连拱隧道中墙优化分析
Meanwhile, it is found that the mid-board stress is appropriate with overall compression yet partially with small tension stress through analyzing the results of the completed construction. 结果分析表明,施工完成后,中墙受力较为合理,表现为整体受压,只有局部有很小的拉应力存在。
