摘要
Taking concrete engineering for an example, statistical analysis between unloaded zones limited by qualitative index and coefficient of permeability in corresponding range of role has been carried out, and its average value was taken as the partition limit for unloaded zones. The application results indicate that as one of the quantitative classification indexes, the coefficient of permeability has its own advantage, and the depth of unloaded zone partitioned with coefficient of permeability was coincident with the ones with other means. Finally, the mainly problems of unloaded zones partitioned by coefficient of permeability was discussed.
