摘　　要：考虑到地质条件的复杂性和输油管等重要设施的存在,水下炸礁作为港口建设和航道疏浚中的重要工作手段需要确保工程的安全性。为了减少爆破产生的冲击波、震荡及爆破涌浪对周围环境的危害,对地质条件进行充分分析,并选取合适的爆破自由面以降低爆破振动的影响。在进行水下炸礁工作时,开展试爆研究,通过调整爆破参数如装药量和引爆时间,达到最佳的效果;通过设计最佳的装药结构,提高爆破的稳定性和安全性。研究成果可为地质坚硬、水深较深、施工条件复杂以及需要确保施工区内重要建筑安全的水下炸礁工程提供技术参考。Considering the complexity of geological conditions and the existence of important facilities such as oil pipelines,underwater reef blasting,as an important means of port construction and waterway dredging,needs to ensure the safety of the project.To reduce the harm of shock waves,vibrations,and blasting surges generated by blasting to the surrounding environment,this study conducts a thorough analysis of geological conditions and selects appropriate blasting free surfaces to reduce the impact of blasting vibration.When conducting underwater reef blasting work,trial blasting research is conducted to achieve the best effect by adjusting blasting parameters such as charge amount and detonation time,and the stability and safety of blasting can be improved by designing the optimal charging structure.The research results can provide technical references for underwater reef blasting projects with hard geology,deep water depth,complex construction conditions,and the need to ensure the safety of important buildings in the construction area.
