摘要
在钻爆法隧洞施工过程中,围岩的节理裂隙对岩体爆破效果的影响最为显著。通过对凤凰寨隧洞施工过程中不同地质条件进行分析,总结不同地质条件对钻爆施工的影响,并针对不同地质问题提出了相关改善爆破设计的建议,取得了预期的效果。
In the tunnel construction with the drilling and blasting method,the joint fractures in the surrounding rock are of the greatest influence on the blasting effect.Considering the different geological conditions encountered in the blasting construction of Fenghuangzhai Tunnel,the influence of geological conditions on blasting construction is analyzed.Then,engineering measures to improve the blasting effect are proposed for different geological issues.Satisfactory results are obtained in practice.
