摘要
文中结合包茂高速中广西段岑水高速公路均昌隧道的实例,对发生的四次重大突泥涌水灾害做了简单介绍,并对灾害发生成因做了阐述,对富水软弱破碎岩层隧道的固结开挖做了施工技术总结。
Combined with the example of the Junchang Tunnel of Censhui Expressway in the middle and Guangxi section of Baomao Expressway,this paper briefly introduces the four major mud and water inrush disasters that occurred,and expounds the causes of the disasters.Consolidation excavation of the tunnel has made a summary of construction technology.
