超大断面海底隧道穿越风化槽施工及方案研究

Study on the Construction and Scheme of the Super Large Cross Section Subsea Tunnel Crossing the Weathered Trough

海底隧道的施工受到多方面自然因素的影响,对于超大断面海底隧道穿越风化槽来说,施工技术和方案都要根据不同的地质及围岩情况进行研究。论文以厦门第二西通道(海沧海底隧道)F6风化槽为例,对不同地质情况采用的施工方案进行研究。

The construction of subsea tunnel has been affected by many aspects of nature, for the undersea tunnel through the weathered trough construction technology and scheme are studied according to the different situation.This paper take the Xiamen No2 west gallery （Haicang subsea tunnel ） F6 weathered trough as a example, study on the construction schemes in different geological situation.
