根据工程实例 ,介绍了在复杂环境条件下进行大型高耸建筑群保护性部分爆破拆除时 ,采用机械预切割、折叠定向倒塌的机械与爆破相结合的综合控制拆除方案。详细介绍了方案的设计思想、实施步骤和实际效果 ,同时就爆破时产生的一些问题进行了探讨。 According to the engineering examples, a comprehensive control scheme of mechanical and blasting with mechanical pre-cutting and collapsible directional collapse is introduced when the protective partial blasting demolition of large towering buildings under complicated environmental conditions is introduced. Described in detail the design concept of the program, the implementation of the steps and the actual results, at the same time on the blasting of some of the problems were discussed.
