| 摘 要： | 出矿时突发产生的高动态应力总是比相应的静态应力大得多,对贮矿工程结构影响很大。本文从理论上分析了产生高动态应力的力学机理及其表现形式,并推导出了估算高动态应力的计算公式。这对防止高动态应力可能产生的危害和设计贮矿系统结构有重要意义。

| Abstract: | The high dynamic stresses occuring suddenly during ore drawing are always much higher thanthe corresponding static stresses and have a great influence on the ore storage engincerig structures.Its forming mechanism and manifestation have been analysed in theory and the calaulation formulashave been deduced in this paper. The result is of great significance for protecting the storage systemfrom harm and for guiding its design. |
