| 摘 要： | 应用RFPA^2D程序模拟雁列和共线非连通两种非连续断层的应力场和声发射场，并与相同条件下的热红外辐射成像试验进行对比，分析非连续断层的温度场与应力场及声发射场之间的关系。研究结果表明：数值试验的声发射与实际试验中的热红外辐射温度具有类似的时序变化阶段和空间演化特征。通过对热红外图像与应力场的比较以及对裂纹破裂模式的分析，讨论试件各裂纹表现出的红外辐射特征差异，以进一步了解非连续断层的破裂过程和破裂机制。 |

| Abstract: | The stress field and acoustic emission(AE) field of two kinds of discontinuous jointed faults,en-echelon faults and collinear disconnected faults,are numerically simulated using rock failure process analysis code(RFPA2D).The thermal infrared radiation(TIR) from the loaded rock surface of modeled jointed faults is detected by a TIR imager,and the experimental boundary conditions are similar to that of numerical simulation.The detected TIR is analyzed and compared with the numerical test results of AE.It shows that the spatio-temporal characteristics of TIR radiation and AE are similar.Besides,by comparing the TIR images with the stress field and visible light photos,it is revealed that the TIR from different cracks,such as the wing crack and shear crack,present different characteristics.The physico-mechanical mechanism of the TIR abnormal and difference are discussed. |
| Keywords: | remote sensing rock mechanics(RSRM) discontinuous jointed faults thermal infrared radiation stress field numerical test |
