在改造旧城区的拆除工程中,控制爆破技术的应用,已日益普遍。一些从事爆破技术研究的单位和部门,成功地应用控制爆破技术拆除房屋、大楼的实例,已屡有报导。如铁道部第四勘测设计院控制爆破研究室,自1980年以来,在设备密集的工厂区,上海闹市区十字交叉路口等处,分别应用“内合坍落法”和“折叠倾倒法”爆破拆除了二至四层的框架大楼三座,(另有三座待拆的大楼正在按新的拆除工艺
The application of controlled blasting technology has become increasingly common in the demolition of old urban areas. Some units and departments engaged in blasting technology research have successfully reported the use of controlled blasting technology to demolish houses and buildings. For example, in the Controlled Blasting Research Laboratory of the Fourth Survey and Design Institute of the Ministry of Railways, since 1980, in the equipment-intensive factory area, at the crossroads of Shanghai downtown, etc., the “inside collapse method” and “fold collapse method” have been applied. Two to four-story frame buildings were dismantled (another three buildings are being demolished according to the new dismantling process
