梅关隧道设计施工技术

Design and construction technology of Meiguan tunnel

梅关隧道是广东韶关至江西赣州高速公路南雄至大余段的一个关键性控制工程。隧道穿越数条大断层横切的地质复杂的板岩地段,且隧道大部分属于浅埋大跨偏压,对设计、施工有一定影响。为确保工程的顺利进行,设计、施工、监理和监控单位紧密配合,采取了先进的施工技术和科学的管理方法,较好地攻克了各施工难点,取得了满意的效果。文章对该隧道设计和施工进行了简单介绍,力求为相应条件下的隧道设计和施工提供参考。

Meiguan tunnel is the key project from Shaoguan Guangdong to Dayu Jiangxi in Shaogan Express, wmcn crosses sheet stone cut by several large faults, and it has bia-pressure ,big span in site of the tunnel door, which has great influence on design and construction. In order to keep the project running smoothly, the design, con- struction,monitoring, and test units cooperate tightly, and good effect has been gained. The design and construction methods about Meiguan tunnel is briefly introduced in this paper. The content of this paper will provide some useful reference for similar underground engineering.
