摘要(Abstract)：

在对广州市旧体育馆爆破拆除的抑尘系统进行可靠性评价时,应用了可靠性理论。本文简介了该工程抑尘系统的构成,概述了该系统故障树的构建。通过计算,得出了基本事件的重要度次序。同时,分析了理论结果与实际结果不同的原因。文章认为,运用可靠性理论有助于决策者全面了解抑尘系统的情况和找出主要矛盾,减少系统失效的可能性。
Reliability theory was used to evaluate the reliability of a dust-control system applied in the blasting demolition of old Guangzhou Gymnasium Building. In this paper, the composition of this system was briefly introduced and the establishment of fault tree was outlined. Through the calculation, a sequence of basic events according to their importance degree was gained. At the same time, the causes for the difference between theoretical and practical results were analyzed. It was considered that application of reliability theory is helpful for a policymaker to know the condition of a system completely and find out the key factors of an object system, decreasing the possibility of system failure.
