| 摘 要： | 开展了碳酸盐岩（灰岩、白云岩）溶蚀作用实验室模拟研究，建立了溶蚀作用的热力学模型方程，对3种不同温压条件下（348．15K，20MPa;373.15K,25MPa；403．15K，30MPa)碳酸盐岩溶蚀作用进行了定量研究，提出了白云岩较灰岩更易溶解并形成孔隙、孔洞等古溶蚀构造，这为油气生成提供了地下空间；同时提出了在城市、铁路及隧道选址等方面充分考虑地下工程地质概貌，以免发生重大的地质灾害及其隐患。

| Abstract: | The dissolution of carbonate rocks is simulated by experiments. The thermodynamic equations are derived to study the dissolution quantitatively under 3 temperature and pressure conditions, namely, 348.15 K and 20 MPa, 373.15 K and 25 MPa, and 403.15 K and 30 MPa. Dolomite is much easier to dissolve and lead to deposition of oil and natural gas than the limestone is. The engineering geologic significance of the study is that the geological conditions should be considered for the location of a new city, railway, tunnel, and so on, to avoid the risk of geological disasters. |
