| 摘 要： | 根据型钢水泥土的特性，提出了组合结构的本构模型．经分析将组合结构受力破坏过程分为四个阶段，推导了各阶段内力与变形的计算式．通过算例和试验结果对比，指出水泥土对组合结构的贡献主要表现在限制了型钢的侧移，有效地保证了结构的整体稳定性，在弹性阶段对强度和刚度贡献较小，在塑性阶段贡献有所提高．

| Abstract: | According to characters of shaped steel and cement soil, the model of combined structure was advanced. The course of combined structure from beginning to invalidation under the load can be divided into four phases. The formulas calculating moment and deformation were educed, too. According to results of calculation and experimentation, it proved that the contribution of cement soil was major to restrict the lateral movement of shaped steel and insure the stability of combined structure efficaciously, while the contribution to intensity and rigidity was less in elasticity phase and increasing in plasticity phase. |
