| Abstract | 冰盖结构的动力特性属于流固耦合系统中的动力学问题.根据黄河凌汛的特点和现场破冰试验采集的数据,研究了冰盖前20阶振型、不同厚度下自振频率和阶次的关系、自振频率和水深的关系等.研究结果有助于提高定向爆破的效率. |
| Other Abstract | The dynamic characteristic of ice-cover structure was the dynamics problem in the fluid-solid-interaction system.On the basis of Yellow River ice flood’s feature and data collected in field breaking-ice test,the paper analyzed twenty-order shake models prior to ice-cover,the relation of natural frequency and order,and the relation of natural frequency and water depth.The research results will help improve efficiency of directional blasting. |
