| 摘 要： | 襄渝铁路十堰四号隧道多处为浅埋暗挖段，在地质因素、地下水和施工因素的影响下易发生过大沉降导致地面建筑物和隧道失隐。为最大限度减少对围岩的扰动，施工中采取地表水截流、沟内铺设防水板，洞内地下水引排，洞内开挖采用控制光爆、加强超前与初期支护等措施，有效地控制了地表沉降。

| Abstract: | The No.4 Tunnel at Shiyan of the Xiang-Yu Railway consists of a number of shallow-cut sections.Due to the geological factors,groundwater and construction factors,excessive ground settlement may happen,which will result in the instability of ground buildings and tunnels.To minimize disturbance to the surrounding rock,technical measures,such as stopping surface water,laying waterproof boards in tunnels,draining underground water inside the cave,adopting the smooth-faced blasting excavation inside the tunnel,a... |
