基于Markov过程的地下工程进风系统可靠性评估模型

Reliability Assessment Model of Substructure Air-Input System Based on Markov Process

现代条件下的地下工程建设与改造对可靠性的要求极高.地下工程进风系统在整个工程中具有十分重要的作用,更需要高可靠性保证.介绍了地下工程进风系统的特点,根据地下工程常见的两种进风系统方案提出假设,建立了一种基于马尔科夫(Markov)过程的可靠性概率模型,通过系统可用度计算,对地下工程进风系统可靠性进行了评估.

The substructure construction and reconstruction under comtemporary conditions require extremely high reliability.The substructure air-input system fulfills a very important function in the whole engineering and needs to a fuller extent the high reliability assurance.This paper presents the characteristics of substructure air-input system,suggests a hypothesis in light of its two common schemes to establish a probabilistic model for reliability based on Markov process,and evaluates its reliability by means of system usability calculation.
