为探究加载速率对碳纤维(CFRP)布被动约束煤能量演化特征的影响规律，利用SAM–2000型电液伺服岩石力学试验系统，开展了不同加载速率下CFRP被动约束煤样单轴压缩试验。研究结果表明：CFRP被动约束煤样总能量随轴变形增加呈以“下凹状”渐增至某平稳斜率，单层工况下平稳斜率均小于双层的，且前者斜率增速大于后者的，但最大加载速率下其平稳斜率为断崖式骤增；峰值点总能量及其增长比均随CFRP层数的增加而增大，且CFRP层数对煤峰值点总能量及其增长比影响的显著性明显优于加载速率的，获得了不同速率下峰值点总能量增长比的函数演化规律，并建立了兼顾考虑加载速率与CFRP层数的响应曲面；当加载速率最小(大)时，峰值点耗散能率增长比均随CFRP层数增加而减小，且最大加载速率下其值约为加载速率最小时的6.03～8.87倍，在速度1.67×10⁻³～1.67×10⁻² mm/s内，峰值点耗散能率及其增长比均随层数增加而增大，获得了不同加载速率下峰值点耗散能率增长比的函数演化规律，并建立了兼顾考虑速率与CFRP层数的响应曲面；被动约束煤样弹性能耗比随轴变形增加呈现先快速陡降过渡为缓降至稳态拐点后又从缓增过渡为快速陡增的特点，呈“鱼钩”状，在峰值附近的弹性能耗比出现连续形似阶梯状突变，表明裂隙在快速发育。

In order to study the influence law of energy evolution characteristics of coal confined passively by CFRP sheets. A series of uniaxial compression tests of coal confined passively by CFRP sheets were carried out under different loading rates by the SAM–2000 rock mechanics test systems. The research results show that with the increase axial deformation, the total energy of coal confined passively by CFRP sheets first increase gradually with a “fovea inferior”, and then reaching a stable slope. The stable slope in the single-sheet condition is smaller than that in the double-sheet one, and the increase of the slope is larger than that of the latter one, but the stable slope at the maximum loading rate is cliff-like steep increase. With the increase of CFRP layers, the total energy of coal at peak and its growth ratio also increases. The effect of CFRP layers on the total energy of coal at peak and its growth rate is significantly better than that of the loading rate. The function evolution law of the total energy growth rate at peak under different rates is obtained and established a response surface considering rate and CFRP layers. When the loading rate is at its minimum or maximum, the dissipated energy rate growth ratio at peak decreases with the increase of CFRP layers, and the value at the maximum loading rate is about 6.03−8.87 times more than the value at the minimum rate. In the loading rate ranges from 1.67×10⁻³ mm/s to 1.67×10⁻² mm/s, the peak dissipation energy rate and its growth ratio also increase with the increase of the CFRP layers. The function evolution law of the dissipated energy rate growth ratio at peak under different loading rates is obtained, and the response surface considering both loading rate and CFRP layers is also established. With the increase of axial deformation, the elastic energy consumption ratio of CFRP passively confined coal has a transition from rapid steep drop to steady inflection point and then from slow increase to rapid steep increase, which is like a “fishhook” shape. The elastic energy consumption ratio near the peak shows a continuous step mutation, indicating that cracks are developing rapidly.
