摘　　要：为了判断拆除爆破高耸建筑物能否倾倒,以设置坐标系的方法,通过几何关系求得建筑物倾斜时的重心位置和侧面轮廓线各拐点的坐标值,再用计算公式求出侧面面积,最后用面积矩法求出重心位置。将相关计算式和参数输入Excel表,可以便捷地对建筑物倾倒的可靠性作出判断。In order to judge whether a high-rise building can be dumped by demolition blasting,the position of the center of gravity when the building is inclined can be obtained by setting coordinate system and the coordinate values of each inflection point of the side contour line,then the side area is calculated by using the calculation formula,and finally the position of the center of gravity is obtained by using the area moment method.By inputting the above related formulas and parameters into Excel table,the reliability of building dumping can be judged conveniently.

关 键 词：拆除爆破 建筑物倾倒验算 Excel计算判断 重心 面积矩
