摘要
There are many factors to influence the advantage of water-sealed underground oil tank sites,such as geological environment,geological environment and construction convenience. Firstly, ten influence factors such as geologic structure,geomorphology, rock mass strength,and so on, which are generalized from the engineering geological conditions, technologic and economic conditions and construction conditions are put forward on the base of survey and prospecting work of the first underground state oil reserves in China, and their corresponding quantitative indexes are determined. Then the classification criterion of the water-sealed underground oil tank sites was proposed. Based on the criterion, the extension method was used to evaluate the water-sealed underground oil tank sites. Finally the program was applied in the Huizhou water-sealed underground oil tank engineering.
