【摘要】 目前,由于地质条件的变化,大多数建基面往往不在同一工程,甚至有的在同一坝段岩石变化较大,因此,在坝基建基面开挖过程中,由于在爆破过程中高程差异处,基岩受力复杂,根据施工现场爆破现场分析原因,总结工程经验。更多还原

【Abstract】 Due to changes in the excavation of geological conditions,most often in the same bearing surface engineering,even some larger changes in the same dam,therefore in the rock foundation excavation of the bearing surface process,because in the process of blasting height differences,rock stress is complex,according to the construction site,summary analysis of blasting engineering experience.更多还原
