摘要:
冷却塔稳定的塔体结构，在定向拆除爆破中易出现塌而不倒、爆堆过高等问题。因此，在爆破设计中，合理的爆破切口形状是冷却塔顺利爆破的关键因素。以某电厂两座结构相同、爆破切口形状不同的冷却塔爆破拆除为工程背景,利用ANSYS/LS-DYNA软件对两座冷却塔进行数值模拟分析。通过对比不同爆破切口形状下两座冷却塔的数值模拟结果与爆破施工现场的爆堆高度、触底速度等评价指标,得到：复合型爆破切口在倒塌范围、爆堆高度、爆破振动等方面均优于矩形爆破切口。
Abstract:
Due to the stable structure of the cooling tower, problems such as incomplete collapse and excessive stacking are prone to occur during directional demolition blasting. Therefore, in blasting design, a reasonable shape of the blasting cut is a key factor for the smooth blasting of the cooling tower. Taking the blasting demolition of two cooling towers in a power plant with the same structure and different shapes of blasting cuts as example, numerical simulation analysis was conducted using ANSYS/LS-DYNA software. By comparing numerical simulation of the two cooling towers with different shapes of blasting cuts and evaluating indicators such as pile height and bottom contact speed at the blasting construction site, it is found that the composite blasting cut is superior to the rectangular blasting cut design in terms of collapse range, pile height, and blasting vibration.
