| 摘 要： | 分析了目前框架楼房定向倒塌爆破切口高度的确定方法。根据建筑物倾倒力学原理,对建筑物定向倾倒作出简化模型,用几何方法得出炸高范围公式,并对公式进行了讨论,得出文中公式(8)是计算楼房整体倾倒炸高的合理范围公式。通过实例计算,证明了这种计算方法的可行性。

| Abstract: | In this paper,the currently used calculation formula on blasting cut height for directional collapsing of frame buildings was analyzed.On the basis of the mechanical principle,a simplified model for directional collapse of buildings was presented and a calculation formula on the height of blasting cut was proposed and discussed.With the formula the reasonable scopes for collapse and blasting height were produced,and moreover,the feasibility of this calculation method was approved through the practical examples. |
