| 摘 要： | 在复合地基工后沉降计算中，加固区域采用复合模量法；而下卧层则采用应力扩散法计算层顶附加应力，再用分层总和法计算沉降。同时利用计算结果分析路基工后沉降与桩长和压缩模量的关系。通过水泥搅拌桩软土地基的沉降和承载力计算，验证水泥搅拌桩处理软土地基的正确性、合理性。

| Abstract: | In calculation of post-construction settlement of composite foundation, composite modulus method was applied to reinforcement area, stress diffusion method to underlying layer to calculate the additional stress on top surface of the layer, and then layer-wise summation method to calculate the settlement. By use of the calculation result, the relation between post-construction settlement of subgrade and pile length, compression modulus was analyzed. Through calculation of settlement and bearing capacity of the soft foundation with cement mixing piles, the validity and reasonability of such treatment is verified. |
