摘　　要：根据利文斯顿爆破漏斗理论,分析了影响爆破漏斗形成的相关因素,并在蒲津路爆破工程项目中设计了系列单孔爆破漏斗实验,实验收集的数据用SPSS软件进行回归分析,对现场使用的乳化炸药的特征曲线、爆破漏斗体积与埋深的关系、漏斗半径与炸药埋深的关系进行了分析研究,求出最佳埋深,应用实验结果指导工程实践,得到了较好的爆破效果。According to the blasting crater theory preseted by Livingston,the factors influenced the formation of blasting crater are discussed,series of crater experiments of single hole blasting were performed in blasting project of Pujin road,the date from experimental design were analyzed by SPSS software,the relationship between blasting crater volume and change embedment depth,the relationship between crater vatius and charge enbedment depth have been discussed,the optimum depth has been found out. Applying the results to guide angineering practice,obtained the good blasting effect.
