tunnel axis meaning in English
风洞轴
Examples
- It was shown that the maximum displacement occurred on the tunnel axis when one tunnel was excavated , while the maximum value happened near the shallow tunnel and between the area of two tunnels when two adjacent tunnels were excavated at the same time
分析结果表明：单条隧道开挖引起的地表最大沉降值出现在隧道轴线的正上方，而两左右或上下相邻隧道开挖的地表及土层内部的最大沉降值则出现在两隧道的纵轴线之间，且偏向上方埋深较浅的隧道。 - Based on matlab system , a multi - layer back propagation neural network model was developed , in which the effects of the depth from surface to the tunnel axis , tunnel diameter , groundwater level , as well as the elastic modulus , shear strength , side pressure coefficient and unit weight of soil and the space between excavated wall and lining on the ground subsidence were considered
采用matlab系统开发了一个多层反向传播神经网络模型，考虑了隧道的深度、隧道的直径、地下水位、土的弹性模量、土的剪切强度、土的侧压系数、土的重度和开挖间隙对地表沉降的影响。
