矿井支护系统可靠度熵函数研究

Study on function of reliability degree entropy of support system in mines

利用信息熵与结构可靠性理论建立了矿井支护系统可靠度熵函数,它综合了信息熵与可靠度指标的特点,是系统平均可靠性的度量。它既表示设计时期的可靠度指标,又考虑使用阶段可靠性控制的难易程度,适合矿井支护设计条件的特点。

The paper draws on theory of information entropy and structural reliability to establish function of reliability degree entropy of support system in mines. It combines characteristic of information entropy and structural reliability index and express average system reliability. Function of reliability degree entropy shows reliability degree index of design period and the difficulty- easiness grade of using session of reliability controlled. It is more adapted to the condition of supporting design in mines.
