摘要(Abstract):
采用减少坍塌距离的爆破方式爆破拆除复杂环境下高耸框架,通过选取适当的爆破高度及前后排的爆破高差、合理的起爆顺序及起爆时差、合理的爆破参数及装药结构,有效地控制了框架的倒塌距离、后坐距离和横向位移。
This paper presents an example of demolition of high frameworks in complicated surroundings by blasting to reach directional falling into the controlled collapse scope.In the blasting the collapse-reaching scope,the base backward movement and the horizontal movement of the frameworks were effectively controlled by selecting or determining the blasting parameters as the rational heights of demolition,the rational height difference in demolition,the rational detonating sequence,the rational detonating time difference between parallel rows,and optimized demolition parameter and charge structure.
