摘要
在大地回春季节,黄河流域河流解冻导致大块的冰凌顺流而下,极易发生"武开"河,即在此时节易发生冰塞、冰坝等凌汛灾害,对黄河沿岸人民的生产和生活造成影响。利用ANSYS/LS-DYNA建立了炸药在冰下的爆破模型,研究了在相同装药量,不同炸点距离下,爆炸破冰对堤防的影响。通过对结果的分析,分别得出了在冰内爆炸和在冰下爆炸的安全距离。
In the earth rejuvention season,the Yellow River is thawed let to large pieces of ice down prone to＂Wu Kai＂River. In this time,the melting ice flood disasters occurred,such as ice jam and ice dam,which influence along the Yellow River people＇s production and life. This essay by ANSYS/LS-DYNA. The influence of the explosion on the embankment was studied under same explosive load and different explosive distance,and obtained the stress curve. Through the analysis of the results,the safe distance of explosive under ice and in ice are obtained respectively.
