| 摘 要： | 公路隧道下方有过水隧道穿越,隧道的开挖卸荷必然会对既有过水隧道产生影响。某高速公路隧道K21＋450~480段下方有过水隧道穿越,本段隧道为小净距隧道,处在软弱Ⅴ级围岩中。本文通过数值计算,从位移、弯矩、应力等几个方面探讨了过水隧道的稳定性。

| Abstract: | A water tunnel cross the road tunnel from below, tunnel excavation unloading will inev- itably impact on the water tunnel. An expressway tunnel is crossed by a water tunnel from below in the K21 ＋450 -480 period, this section of the tunnel is the small clear distance tunnel in weak V level of surrounding rock. This paper discusse the stability of water tunnel from displacement,bending moment and so on stress through numerical calculation. |
