| 摘 要： | 岩石遇水膨胀不仅引起岩石体积增加．而且显著消弱岩石强度。本文在现有研究成果的基础上，分析了各种膨胀理论的适用条件；通过理论推导，得出了求解岩石遇水膨胀引起的巷道底臌的表达式．最后进行了实例分析，讨论了膨胀对底臌的影响程度及与之相关的因素。

| Abstract: | The swelling of rock meeting with water not only leads to the increase of rock volume,but also reduces the strength of rock. Based on the present achievements, the suitable conditions of swelling theories are analysed. Through theoretical deductions, the formulas to calculate the floor heave caused by swelling are obtained. Finally, the field case is caculated, the affecting degree to floor heave by swelling and the factors related to it are analysed. |
