【摘要】 水下生态清礁是目前航道工程亟待解决的问题，对于保护水下生物栖息地、维护生态平衡、提高航道安全性起到了重要作用。通过梳理生态清礁的相关理论文献，总结生态清礁的方法及其局限性；并进一步介绍兼具生态和高效的2种新型生态清礁方法，介绍相关数值模型构建方法及研究方向，得出结论：1）针对高/低频振动清礁技术，刀头频率在20～30 Hz之间最佳；2）针对气体胀裂破岩技术，堵塞物能显著增强胀裂效果。旨在为之后探究生态清礁破岩机理以及未来优化方向提供信息。更多还原

【Abstract】 Underwater ecological reef removal is a pressing issue for current waterway engineering. It plays an essential role in protecting underwater habitats, maintaining ecological balance, and enhancing channel safety. By reviewing relevant theoretical literature on ecological reef removal, this paper summarizes the methods and limitations of ecological reef removal, and further introduces two new ecological and efficient reef removal methods. Additionally, it discusses relevant numerical model construction methods and research directions. The conclusions are as follows: 1) For high-low frequency vibration reef removal technology, the optimal cutter head frequency is between 20 and 30 Hz; 2) For gas expansion rock breaking technology,blockage significantly enhances the expansion effect. This study aims to provide information for further exploration of ecological reef removal mechanisms and future optimization directions.更多还原
