| 借助于无扰动细观动态监测CT技术和化学动力学分析方法，研究了钙质胶结砂岩受酸腐蚀的渗透力学特性，建立了岩样渗透破坏深度、单轴抗压强度、CT数与岩石密度之间的关系式。推算了不同时段溶液的浓度，并对计算结果进行了初步验证。 |

| Mechanical properties of homogenous sandstone subjected to hydrochloric acid attack |
|
|
| Abstract: |
| The mechanical properties of calcareous cementitious feldspathic sandstone specimens impregnated in 0.1 mol/L hydrochloric acid solution was studied by means of χ-ray CT scanning of nonstructive detecting and chemical reaction equation.The mechanical model was proposed and the functional relationship with the depth of corrosion,uniaxial compressive strength,CT numbers and density of rock specimens was established.The sdution concentration of different stages were calculated and the results were tested preliminarily. |
| Key words: homogenous sandstone hydrochloric acid attack impregnated mechanical properties χ-ray CT scanning |
