中国科学院力学研究所最近用控制爆破方法成功拆除了一座钢筋混凝土烟囱。烟囱位于科学院居民区内,四周是居民楼,最近的距离7m,最远的41.5m.烟囱高38m(另有2.7m避雷针),只有东南方向二座楼房之间有24度角的夹缝可供安全倒塌。烟囱下部结构为南北轴线对称,南壁是205×335cm的烟道
The Institute of Mechanics, Chinese Academy of Sciences recently successfully demolished a reinforced concrete chimney by controlled blasting. The chimney is located in the residential area of the Academy of Sciences and is surrounded by residential buildings. The nearest distance is 7m and the farthest is 41.5m. The chimney height is 38m (another 2.7m lightning rod). Only the southeastern two buildings have a gap of 24 degrees. Security collapsed. The lower chimney structure is symmetrical about the north-south axis and the south wall is a 205 x 335 cm flue
