| 摘 要： | 阐述了采用控制爆破技术在复杂环境下拆除大型基坑内钢筋混凝土支撑的方法。在特殊的环境条件下进行支撑爆破时,采用预先切断振源、减少单段起爆药量的防震方法以及搭建防护棚的方法,可以有效控制爆破振动、飞石、扬尘对周围的影响。实践证明,采用控制爆破技术拆除大型基坑内钢筋混凝土支撑是安全、高效的。

| Abstract: | The paper described the method of demolishing reinforced concrete supporting internal large foundation pit by controlled blasting under complicated environment.When demolishing the reinforced concrete under special environment,cutting vibration source in advance,reducing single-section amount of primary explosives and putting up protection shed can effectively control the influence of blasting viboration,flying rock and fugitive dust to surroundings.It has been proved by practice that demolishing steel reinforced concrete supporting internal large foundation pit by controlled blasting is safe and efficient. |
