摘要(Abstract)：

宁波市大榭岛关外深路堑爆破开挖工程中进行了２０多次深孔光面爆破，光爆面积达１６５００ｍ２，取得了很好的爆破效果。保证了高边坡的稳定。光面爆破技术要求高、难度大，通过对历次光爆效果的分析，在光爆的参数设计、装药结构、起爆方法诸方面取得了较成功的经验。文中对高边坡光爆与其他处理方法进行了比较，认为高边坡光爆处理方法从保证工程质量、减少刷坡工程量，以及确保高边坡的稳定、安全等方面优于其他高边坡爆破处理方法。
The author carried out the deephole smooth blasting for more than 20 times with total area of 16500 quare meters in the excavation for deep cuts on Daxie Island,Ningbo and gained excellent blasting results,therefore ensured the stability of highside slopesThough the mentioned blasting requires high technology,we have obtained successful experience in the design parameter,charge structure and detonation method by analyzing every smooth blastingCompared with other treatment methods adopted for highside slopes in this article,the smooth blasting was considered to be better in the aspects of ensuring project quality,the stability and safety of the highside slopes
