摘要
根据厦门翔安海底隧道过风化深槽施工的工程实践经验,介绍了在可能发生灾害性的突泥、突水、塌方和诱发地面塌陷而导致海水下灌等地质灾害的情况下,如何采取超前地质预报、设置防水闸门、超前管棚及全断面帷幕注浆等施工辅助措施,从而保证了过风化深槽施工的顺利进行。
On basis of the engineering practical experience in the crossing of the deep weathered channel of Xiang＇ an sub-sea tunnel in Xia-men, China, the author presents such assistant construction measures as advance geology forecasting, water-resistant gate installing, large pipe roof construction and full-face curtain grouting that are taken with such risks as disastrous mud burst, water burst, collapse, ground subsidence and sea water inflow. Due to the above-mentioned measures, the tunnel crosses the deep weathered channel successfully.
