【摘要】 在黄河上游高纬度河段的凌汛期,频繁出现的冰塞、冰坝等,极易造成壅高河道水位,漫堤决口等险情,对沿黄地区人民生命财产构成极大威胁。冰凌爆破是当前黄河防凌减灾的重要手段之一。本文通过大量现场试验与有限元数值模拟,分别对炸药在冰体内部、冰体表面以及水下爆炸等破冰机理进行了研究,其研究成果可为不同作业方式冰凌爆破提供参考。更多还原

【Abstract】 During ice melting period in the upstream section of high latitude of Yellow River,ice block and ice dam occur in some sections of the river which cause increased water level and risk of river dam breaking.This posts a life and property threat to the people along the river area.Ice explosion is one of the current methods to be used to prevent and reduce this kind of disaster for Yellow River.Many on site experiences and finite element simulation methods have been used in this study.Research has been conducted on the mechanism of ice explosion for the explosives inside ice on top of the ice and under the ice as well,respectively.The results can be used as reference for different kinds of ice-broken explosion.更多还原
