摘要
针对采用安全系数法来评价支架可靠性所存在的问题,在对其进行不确定性分析的基础上,将工程结构可靠性评价方法与支架支护理论相结合,推导出一种回采巷道支架支护的可靠性评价方法.
In the right of the problem existing in traditional assurance coefficient method, this paper, based on the nonderterminacy analysis of bear frame support ,combining the reliability evalution of engineering structure with the theory of bear frame support, develops a method of reliability evaluation of bear frame support of extraction drift.
