    An analytical theory for consolidation of double layered composite ground with granular columns considering the stress concentration effects is presented, and the orthogonal relation of double layered system of such ground is obtained. A lot of calculations are performed based on the solutions and the corresponding results are introduced diagrammatically, from which the consolidation characteristics of composite ground are investigated and discussed. The geometric parameters and modulus of compressibility of granular column have great influence on the consolidation process. The average consolidation degrees defined by excess pore water pressure and settlement respectively are different to some extent. The consolidation degree calculated by the existent theory is smaller than that calculated by the proposed theory in this paper.

    The analytical solution of the studied problem of consolidation of composite ground with granular columns under time\|dependent loading universal in practical engineering are presented. These solutions and relevant computations were used to investigate the influences of the loading time and a few ground parameters on the consolidation process. It is shown that, the longer the loading time, the slower the consolidation rate. The ratio of radiuses, the ratio of column radius and column length, the compressibility modulus of the column body, all affect the consolidation process significantly. Differences exist between the composite ground consolidation characteristics calculated by the two seepage models respectively. For the same ground parameters, the consolidation rate of composite ground with granular columns is fastest if the radial and vertical drain within the column is considered.
