| 摘 要： | 利用自行研制的压缩蠕变试验装置,对煤样进行了蠕变试验研究,根据试验结果,将蠕变强度与瞬时强度进行了比较,拟合得出了蠕变曲线经验公式,认为蠕变试验曲线接近对数规律,建立了蠕变理论模型,并求出了相应的参数.

| Abstract: | The study on creep test of Jincheng coal is run by using the self- developed apparatus of creep test under uniaxial compression.The creep strength is compared with the instantaneous strength based on the test results.An empirical formula of creep curve is fitted and it is considered that the creep test curve is approximate to the logarithmic rule.The theoretical model is established and its parameters are obtained. |
