水底隧道穿越风化槽技术及施工效应研究

A Study on Technic of Benthic Tunnel Traversing Weathered Trough and Its Construction Effect

通过对厦门东通道水底公路隧道风化槽的工程特性分析,结合国内外钻爆法的成功实例,并借助数值分析方法,优化隧道穿越风化槽的施工工艺,确定了超前注浆加固的时机和注浆加固的范围。

By the analysis of engineering character about weathered trough of benthic highway tunnel traversing the Xiamen East Passage Channel and successful examples of drilling and exploding methods at home and abroad,the time of advanced grout reinforcement and the scope of construction techniques for traversing weathered trough are confirmed in virtue of numerical simulation method.
