摘　　要：路基边坡是现代公路工程的重要组成部分,边坡的稳定对公路的安全性有重大影响,而高边坡的开挖方式直接影响边坡的稳定性,既有线的扩建,不仅影响边坡本身,还要考虑对既有线的保护,对边坡开挖也就提出了更高要求。光面爆破和静态爆破是土石方工程中应用广泛两种爆破方式,但单独使用均会影响到施工效果和效率,而采取二者结合的施工方法,既能将施工影响降到最低,又可以确保边坡质量。该文结合案例对此进行了详细介绍,可供参考。Subgrade slope is an important part of modern highway engineering,and its stability has a significant impact on the safety of highway.The excavation mode of the high slope directly affects the stability of the slope.The expansion of the existing highway not only affects the slope itself,but also calls for considerations of the protection of the existing highway,proposing higher requirements for slope excavation.Smooth blasting and static blasting are mostly adopted in earth and rock engineering,but any one of them would affect the construction effects and efficiency when employed alone.The combined use of the two can minimize the construction impact and ensure the quality of the slope as well.This paper provides a detailed introduction based on a case study for reference.
