【摘要】 按线弹性理论,分析给出了倾斜砖烟囱爆破倾倒的方向偏差角的计算式,工程爆破实例验证了这种计算的可靠性。通过数值计算绘成曲线,讨论了不同情况下倒向偏差角的大小,并提出了纠正方法。更多还原

【Abstract】 Based on linear - elastic theory, calculation equations of deviation of toppling direction in sloping onck chimney demolition are provided, the reliability of which have been confirmed by blasting practice. Curves are drawn on the basis of numerical calculation, the scope of deviation of toppling direction is discussed, and measures to rectify toppling direction are suggested.更多还原
