高耸建筑物拆除爆破的安全分析及控制研究

以高耸建筑物拆除爆破的原理为基础,对建筑物拆除爆破中产生的爆破振动、塌落振动、爆破飞石、爆破空气冲击波和爆破噪音等爆破危害的发生机理和影响因素及影响范围进行了分析;并从建筑物拆除爆破中“人”的不安全行为、“物”的不安全状态和“环境”的不安全因素等方面探讨了建筑物拆除爆破中所存在的安全问题;结合一工程实例,分析了工程实例的安全爆破难度,并在此基础上,提出了相应有效的安全防护措施、安全控制措施和安全管理方法。该研究为类似高耸建筑物拆除爆破的安全施工和控制提供了有益的借鉴。

Research on Control and Safety Analysis in Demolition Blasting of Tower Buildings

In this paper,integrating the principium of demolition blasting of buildings and the practice,the general mechanism and affection factors of blasting harms such as blasting shock,collapsing shock,blasting rock,blasting shock wave and blasting noises produced in demolition blasting of buildings are analyzed.The safety problems existed in demolition blasting of buildings are discussed from three aspects such as the unsafe behavior of "person",the unsafe state of "substance"and the unsafe condition of "environment".Based on an engineering example,the difficulty of safety blasting of engineering example was analyzed,on this basis,corresponding effective safety defending measures and the method of safety control are brought forward.This study is significant to the construction safety and control of demolition blasting of similarity tower building in practice.
