高速公路路基石方爆破方法及参数设置

Blasting Method and Parameter Setting of Highway Foundation Stone

路基石方施工中,爆破为重要方法,但需兼顾爆破质量和安全性的双重要求,技术难度较大。论文结合某高速合同段工程实例,为了保证边坡开挖质量,提出运用预裂爆破方法,并对施工方案和技术参数展开了详细的探讨,最终取得了良好的爆破效果,保证了施工过程的安全性。

In the stonework construction of roadbed,blasting is an important method,but the dual requirements of blasting quality and safety must be taken into account,which is technically difficult.In order to ensure the excavation quality of the slope,this paper puts forward the method of slant blasting,and discusses the construction scheme and technical parameters in detail.Finally,good blasting effect is obtained and the safety of the construction process is guaranteed.
