摘要
排水盾构隧道侧向入流点多,管道开孔多,开孔面积较大,隧道开孔大小对隧道结构的内力有显著的影响.通过对相同埋深、不同开孔率下的盾构隧道进行分析计算,得出了其不同工况下的内力变化特征,为类似工程的设计提供一定的参数依据.
Abstract
There are many inflow points,many pipe openings and large opening area in the drainage shield tunnel.The opening size of tunnel structure has a significant impact on the stress and displacement of the tunnel structure.By the simplified calculation and analysis of shield tunnel with the same buried depth and different o-pening rate,the variation characteristics of the stress under different working conditions were obtained,which could provide reference for the design of similar projects.
