兰州南山路工程民大隧道大部分段落距陇海铁路中心线6～8m,混凝土浇注易受到列车振动的干扰。研究过往列车的振动对民大隧道棚洞及框架结构混凝土力学性能的影响,以确定在施工过程中有无必要采取相关措施。依据现有研究成果,在分析新浇混凝土振动影响机理的基础上,研究了振动对混凝土力学性能的影响,提出了民大隧道施工方案。
Lanzhou Nanshan Road project most of the tunnel section from the Longhai Railway Centerline 6 ~ 8m, concrete pouring susceptible to train vibration interference. The effect of train vibration in the past on the mechanical properties of shed tunnels and frame structures of Min Tunnel was studied to determine whether it is necessary to take relevant measures during construction. Based on the existing research results, the influence of vibration on the mechanical properties of concrete is studied based on the analysis of the mechanism of the vibration of fresh concrete. The construction scheme of the Civil Tunnel is proposed.
