| Abstract: | For the prevention and control of the ice jam and ice dam in Yellow River,a new idea of excavating an ice channel on the icecap structure to collect the dynamic flow of ice-jam flood was brought forward.During preparing for the specific ice-breaking equipment,according to research achievements in the new icebreaking theory,the indexes such as the fuse,charge quantity and arrangement of the array of the equipment were designed.Meanwhile,a set of new technical solutions which are of high security,good mobility and strong operability were proposed for ice-breaking and ice-jam removing.A new ice-breaking idea which the blasting action under the ice could make ice materials bend and fracture was presented. |
