基于模糊层次分析法的高楼拆除爆破安全评价

Safety evaluation of the high rise building demolition blasting based on fuzzy-AHP

结合茅台镇高层楼房拆除爆破工程实例,利用层次分析法分析拆除爆破施工中影响安全的主要因素,建立对比判断矩阵,运用模糊评判法计算出楼房拆除爆破中布孔是首要关键的工序,亦是影响爆破安全最主要的因素。通过获取各影响因素的权重,能够让管理者在施工中发现主要影响因素并加强安全管理,有效控制各个因素的危险度,从而提高高楼拆除爆破的安全性。模糊综合分析结果表明,拆除爆破重点在于施工人员的管理,同时完善安全防护措施能够使得爆破施工顺利完成。

Combined with the high rise building demolition blasting in Maotai, the main safety factors of blasting demolition construction were analyzed by AHP （analytic hierarchy process）. The contrast judgment matrix was established. The fuzzy e-valuation method was used to calculate that the hole was the primary key process in building demolition blasting. It was the most important factor affecting the safety of blasting. By obtaining the weight of each influencing factors. Managers could find the main influencing factors in the construction and strengthen the safety management and effectively control the risk of various factors to improve the safety of high rise building demolition blasting. The results of fuzzy comprehensive analysis showed that the key of demolition blasting lied in the management of personnel in construction and we could improved the safety protection measures to ensure the safety of blasting construction.
