摘要:
针对复杂环境下92 m高待拆除双曲线型冷却塔，采用矩形爆破切口、预开定向窗、简化爆破切口和预留支撑墙的定向爆破拆除方案，达到了预期的爆破效果。运用动力有限元软件ANSYS/LS-DYNA对冷却塔的爆破拆除倒塌过程进行了数值模拟，进一步验证爆破拆除方案。数值模拟结果和实际爆破效果对比分析表明，使用ANSYS/LS-DYNA模拟冷却塔的倒塌过程比较符合实际的爆破拆除过程，并可为更好地优化爆破拆除设计方案提供一定的参考。
Abstract:
Blasting demolition plan including rectangular blasting cut, pre-opening directional window, simplifying blasting cut and reserving support wall was carried out and achieved the expected blasting effect in blasting a 92m-high hyperbolic cooling tower within a complex environment. Collapse process simulation of the cooling tower under blasting demolition using the dynamic finite element software ANSYS/LS-DYNA further verified the reasonability of blasting demolition plan. According to comparative analysis between numerical simulation and actual blasting, it was shown that the simulation of the collapse process of the cooling tower by ANSYS/ LS-DYNA fits well with the actual blasting demolition process. It can be used to simulate the whole process of blasting demolition and provide some reference for optimizing the design plan of blasting demolition.
