摘　　要：根据惠州港通用码头陆域平面药包抛掷爆破的实爆堆积测量分析成果 ,结合药包设计的主要参数 ,对平面药包产生的爆破漏斗的范围与形态、不同药包部位的残方比与抛掷率、药包的长抗比与圆柱体药包的应力波形演变关系予以解析 ,供硐室爆破的理论研究。Based on making a survey of real muckpile from throwout blasting with plane charges in Huizhou harbour,Guangdong province,and in the light of main designed charge parameters,the relationship between range and shape of blasting crater,and the ratio of remained rock and thrown rock at different parts of a charge were analyzed In addition,the relationship between the length-burden ratio of a charge and evolution of stress wave shape is studied The conclusion in this paper is available for reference in theoretical research,model test and engineering practice on chamber blasting
