黑龙江防凌爆破试验研究
Breaking ice with explosive in Heilongjiang River
摘要
Abstract
Breaking ice cover or ice jam is essential to prevent flooding in Alpine region.Field experiments have been conducted to study ice-breaking process with explosive in the upper reach of the Heilongjiang River(Amur River)for several years.It is observed that the water depth under the ice cover is a crucial factor affecting crater radius of the breaking ice cover after explosion.Based on the experimental results,a theoretical model is developed to correlate the crater radius and the water depth,the cover thickness,and the explosive charge weight.The application of the model in the Heilongjiang River in 2015-2016 showed good agreement between predicted and measured crater radius.This research provides the scientific basis for breaking ice with explosive to prevent ice disaster in the river of Alpine region.关键词
