摘要
通过对几种岩性岩石在化学腐蚀下单轴压缩破裂过程的细观力学试验,探讨了不同化学溶液对几种岩性岩石单轴抗压强度的腐蚀效应,获得了裂纹扩展过程的显微与全场图像,分析了在化学腐蚀下岩石的细观破裂特征和腐蚀机理,从而为岩石化学损伤力学模型的建立和岩体工程的长期稳定性评价提供了科学依据。
Erosive effects of water chemistry on the uniaxial compressive strength of rocks are studied according to the meso-mechanical experiments, and the microscope images and entire images of the meso-fracturing process are obtained. The meso-fracturing behaviors and erosive mechanism of rock are analyzed under chemical erosion. Therefore, the results can be used as scientific references to set up the mechanical model of the chemical damage of rock and to evaluate the long-term stability of the rock and soil engineering.
