摘要
在隧道工程施工设计中,小净距隧道凭借施工技术要求低、投资成本较小等优点获得广泛应用。文章以河池市境内的G210线大山塘隧道为工程实例,介绍了小净距隧道的间距设计方法,阐述了小净距隧道开挖及支护的关键施工技术,为类似隧道施工提供技术参考。
In tunnel construction design,the small clear-distance tunnels are widely used because of their advantages in low construction technology requirements and low investment costs. With G210 Line Dashantang Tunnel within Hechi City as an example,this article introduced the spacing design method of small clear-distance tunnels,and described the key construction techniques for excavation and support of small clear-distance tunnels,thus providing technical reference for similar tunnel construction.
