摘要
在城市拆除爆破中，用小孔爆破法拆除重心很低、支承面大的浆砌片石构筑物难度很大。本文通过用“集团装药”法拆除此类构筑物的工程实例，介绍这种方法的布药方式、药量计算及其适用条件。
It is difficult to demolish structure which has lower height of gravity center,larger supporting surface and mortar rubble with demolition blasting in city.On the basis of a practical example of blasting engineering with the demolishing method of mass explosive charge,charge pattern,charg ecalculation and application condition of the method is introduced.
