摘要
横琴新区环岛西路南段高边坡爆破工程周围环境复杂且开挖边坡较高。为确保高边坡稳定,同时控制爆破有害效应,采用预裂爆破和台阶爆破相结合的爆破技术,通过缩小预裂孔孔距、适当增加填塞长度、采取间隔装药和预留保护层等措施,达到了确保高边坡稳定,边坡面平整度高的要求。
The environment of southern segment of Hengqin district island ring west road high slope blasting engineering is complex and the excavation slope is high.To ensure high slope stability and control the blasting harmful effect,the combination of presplitting blasting and bench blasting technology was used.Through narrowing presplitting hole spacing,appropriately increasing tamping length,taking deck charging,reserving protection layer and other measures,the stability of high slope was reached,and the requirement that smoothness of slope surface be high was achieved.
