| 摘 要： | 武汉市某19层框-剪结构楼房,拟采用三次双向折叠与定向倾倒相结合的爆破方案进行拆除。本文采用多体运动学数值模拟技术,对不同工况下楼房的空中运动姿态进行了分析,为最终爆破方案的确定提供参考,实际的楼体折叠运动状态与计算机模拟的结果十分接近。该高楼的成功爆破表明,数值模拟技术将为苛刻条件下高层建筑物的精细控制爆破提供有益的参考。

NUMERICAL SIMULATION OF BIDIRECTIONAL FOLDED BLASTING DEMOLITION OF A 19-STOREY FRAME-SHEAR WALL STRUCTURE BUILDING |
| |
| Abstract: | A 19-storey building in frame-shear wall structure was projected to be demolished by combining directional blasting and three times of bidirectional folded blasting.The present paper discussed the use of method of multi-body dynamic numerical simulation in analyzing the collapsing status of the building ,which helped designer to determine the final blasting plan.The success of this project showed that results of numerical simulation quite agreed with the actual folding movement and could supply some helpful references to the demolition of tower building in tough environment. |
