| 摘 要： | 静止散体矿岩压力属主动压力，矿岩内最大主应力迹线偏向于重力线方向，侧压系数小于１．本文根据静止散体矿岩压力的性质，分析了矿岩内的压力分布情况，并推导出散体矿岩静压的计算公式。与传统的扬辛公式相比，该公式的计算结果更符合实际情况。

| Abstract: | The static pressure principle of loose ore and stuff is active,the direction of the majorprincipal stress is approximately vertical and the lateral pressure coefficient is less than one. According to the principle of static pressure, this paper has analyzed the static pressure dis-tribution in loose ore and stuff and deduced the formulas for calculating the static pressure ofloose ore and stuff. Tested by raw data,the calculation formulas are more accurate thanclassic Janssen formulas. |
