杭州市解放路隧道穿越沪杭铁路段,共长41.6m。本段隧道位于直线上,坡率为-0.359%的纵坡。隧道由两座小间距(隔墙厚仅75cm)隧道组成,为双向四车道,采用暗挖法施工。解放路隧道中线对应沪杭铁路里程为K200+942.5,隧道中线与既有线路成80°角度斜交,隧道施工影响行车范围为48m。隧
Hangzhou Jiefang Road Tunnel through the Shanghai-Hangzhou railway segment, a total length of 41.6m. This section of the tunnel is located in a straight line with a gradient of -0.359%. The tunnel is made up of two tunnels with small spacing (only 75cm in thickness), which are bidirectional four lanes and are constructed by undercutting method. Jiefang Road tunnel center line corresponds to the Shanghai-Hangzhou railway mileage K200 +942.5, the tunnel centerline and the existing line at an oblique angle of 80 °, the impact of tunnel construction driving range of 48m. tunnel
