| 摘 要： | 为进一步提高岩溶地质预报的准确性,将分形理论应用于岩溶地质预报.通过对岩溶发育的宏观与微观规律分析,提出了岩溶元的概念,并用于描述岩溶发育的分形生长过程.计算了岩溶元的分形生长维数和岩溶发育的分形评价指数,据此对岩溶发育程度进行判别.将岩溶发育程度分为5级,以2座隧道为例进行了分析,效果较好.研究成果为应用分形理论进行岩溶地质预报奠定了理论基础. |
| 关 键 词： | 岩溶地质预报 分形理论 岩溶元 岩溶发育程度 分形评价指数 |

| Abstract: | To improve the accuracy of karst geology forecasting,the fractal theory was applied.Through the analyses of macroscopic and microcosmic laws of karst,a concept,karst unit,was drawn out,and the fractal growing law of karst was described.Fractal dimension and fractal assessment index of karst were calculated,and they were used to evaluate karst development degree.Five classes of karst were suggested on the basis of the karst development degree.In addition,karst geology forecasting for two tunnels,as examples,were given,and a satisfied result was obtained.The research provides a theoretical basis for karst geology forecasting with the fractal method. |
| Keywords: | karst geology forecasting fractal theory karst unit karst development degree karst fractal assessment index |
