摘要(Abstract)：

位于贵阳市区的贵阳水泥厂有由４个大型筒仓两两相切组成的大容量水泥储仓群（７４０８．４ｍ３）需拆除，单个筒仓内径１０ｍ、高２９．５ｍ。采用水压爆破技术拆除，设计采用多药包布置形式，分５层、每层布６个分药包，并假设分药包为“中心药包”进行药量计算。施爆时注水约５０００ｔ，水压爆破用药量２８７．４ｋｇ，爆破后爆堆高度仅为３ｍ，近１０ｍ的未注水部位的钢筋混凝土也已破碎。爆破安全、高效、拆除过程无灰尘，爆破效果很好，为同类工程提供了可借鉴的经验。
Located at urban district of Guiyang,Guizhou,a huge cement storage with four tubular tanks was demolished by water pressure blasting In the design,multiple charges were arranged in five layers,with six sub charges for every layer The charges in every layer were calculated as a central before blasting,5000t water was poured in the total amount of charges was 289 4kg in the water pressure blasting The height of blasting stack was 3m and the reinforced concrete above water was also broken We have got safe and efficient blasting,and ideal blasting effect without dust,provided referable experience
