公路隧道竖井喷混凝土支护技术研究

研究了公路隧道竖井喷钢纤维混凝土支护技术,并从性能、成本分析方面与普通柱网喷混凝土进行了比较,结果表明：喷射钢纤维混凝土在性能上有较大的优越性,但不具备价格优势,随着以后工程建设的规范和发展及人工费用的增高,钢纤维混凝土会得到推广和应用。

Study on vertical shaft concrete blowout support geochronology in highway tunnel

It studies the steel fiber reinforced concrete support technology with vertical tunnel blowout on highway tunnel,from the aspects of performance and cost,compares it with common column network shotcrete.The result shows that: the steel fiber reinforced shotcrete has relative advantage in performance,but has no advantage on price.With the future specification and development of project construction and increasing of labor cost,the steel fiber reinforced concrete will be widely used.
