| 摘 要： | 建立了耦合条件下岩体的应力-应变关系,推导出不同变温范围条件下巷道围岩的应力和应变.实例计算表明巷道围岩在耦合情况下比非耦合情况下的切向应力、周边位移、破碎区和塑性区半径都有较大的增加,并提出了提高耦合条件下改善巷道围岩体稳定性的措施.

| Abstract: | The stress-strain relation under the coupled condition was created, then the stress and strain were calculated in the different variable temperature range condition. The illustration showed that the shear stress, circumference displacement and the radius of the break zone and the plastic zone were larger under the coupled condition, and the methods to improve stabilization of adjacent rock were given under the coupled condition. |
