英文摘要 | Calcite veins in the sedimentary rocks seal the natural fractures by crystal growth and play a very important role for rocks under compression. The interfaces between the veins and host rock are generally considered as structures determining the mechanical response and fracture of the rocks. Furthermore, thickness variation of the calcite vein also can affect the mechanical behavior and failure of the sedimentary rocks significantly. In this work, carboniferous limestone containing calcite veins were obtained from crop in field, and multiple rock specimens with varying thicknesses of calcite veins were prepared for a uniaxial compression experiment. The mineral identification and investigation were conducted on the rock slices before and after water saturation for analysis of the mineralogical composition. The effect of water saturation on the mechanical behavior was considered due to the presence of clay minerals. Complete stress-strain relationships were obtained through the uniaxial compression experiment. Comuted tomography scanning was employed for the observation of fracture configuration in the failed rock specimens. The mechanical behavior and fractures of the limestone containing calcite veins were analyzed, in which more plasticity and lower strength are generated as the thickness of the calcite veins increase. Depending on the thickness, calcite veins not only can act as the geological structures in the rock but also can join themselves with the host rock to resist compression. |
