摘　　要：从工程实例出发,建立软土地区水泥土搅拌桩复合地基下卧层的固结模型,并通过分离变量法得出该问题的固结解析解及固结度公式,对深入探讨下卧层的一维固结问题及预测下卧层的沉降变形具有理论和实践意义。Based on practical project in soft clay zone, the consolidation model of weak underlying substratum for the composite ground of cement-soil piles is set up. Then analytical solution and degree of consolidation is obtained by variable separation approach. It has theoretical and practical meaning that one dimensional consolidation of weak underlying substratum is discussed deeply and its settlement is prognosed accurately.

关 键 词：复合地基 下卧层 分离变量法 固结沉降
