【摘要】 进行了在化学腐蚀下的花岗岩单轴压缩破裂试验,利用数字显微观测系统对其实时观测。探讨了不同浓度、不同pH值和不同化学溶液对花岗岩表面的腐蚀以及力学特性的影响,分析了在化学腐蚀下花岗岩的破裂行为,给出了荷载-位移变化曲线和对应的显微图像以及各种试件的破裂特征示意图。更多还原

【Abstract】 An experiment of rock fracturing process is conducted under uniaxial compression in order to investigate the behaviors of rock fracturing under chemical erosion. The meso-fracturing process of rock is real-time observed using the microscope and the digital color camera. The effects of rock surfaces and mechanical behaviors are studied under different ionic strengths, values of pH and chemical solutions. The fracturing behaviors of rock under chemical erosion are analyzed. The load-displacement curves, the corresponding micro-images and the schematic diagrams of specimens after failure are obtained.更多还原
