摘要
采用航弹或炮弹轰击冰坝是我国常用的消除凌汛险情手段。随着经济社会的发展,跨河桥梁和水工建筑物逐年增多,加之气象条件限制、弹药弹着点精度低,满足实施轰炸条件的具体地点已很少。统计黄河上游宁蒙河段冰坝形成至自溃(或导致堤防溃口)的历史数据,以2018—2019年度黄河凌汛期观测到的一处冰坝自溃过程为例,在综合分析两类爆破方式效果的基础上,提出在冰坝形成初期采用无人机载破冰弹消除冰坝险情的应用时机和使用方法。
The aerial bombs or shells are often used to bombard against ice dams for eliminating the danger of flood in China.With the devel⁃opment of economy and society,bridges across rivers and hydraulic structures have been increasing year by year and the disadvantages of me⁃teorological conditions,the low precision of ammunition impact points has been becoming more and more prominent,so there are few specific sites that meet the bombardment conditions so far.Based on the historical data that ice dams formed to self⁃burst or causing dyke breach in the history of Ning⁃Meng reach of the Yellow River,taking an ice dam self break process observed in 2018-2019 ice flood season as an ex⁃ample,the application opportunity and method of using airborne bomb by unmanned aerial vehicle to eliminate the danger of ice dam in the early stage of ice dam formation were proposed.
