对大理岩在冲击载荷下拉伸脆断口进行了扫描电镜观察研究，分析了高应变率加载下大理岩的微观破坏断口形貌特征和微观破坏力学机制．通过断口观测和理论分析，明确地给出了大理岩在应变率为10°~101s-1情况下的微观破坏机理，为大理岩拉伸破坏的进一步研究提供了可靠的实验依据．
The tensile fractures of marble under impact loading were studied by scanning electron microscopy. The micro-destructive fracture morphology and micro-mechanism mechanism of marble under high strain rate loading were analyzed. Through fracture observation and theoretical analysis, the micro-destructive mechanism of marble at a strain rate of 10° to 101 s-1 is clearly given, providing a reliable experimental basis for further research on tensile failure of marble.
