摘要
在综合考虑土体双曲线本构模型、增量迭代非线性算法和动力分析中的等价线性化方法的基础上 ,对复合地基进行了地震作用下的动力反应分析。通过一算例指出 :复合地基可以有效地改善天然地基的土力学性能和动力反应特性 ,是符合实际工程需要的地基处理技术。
In this paper, the dynamic analysis of seismic response of a composite foundation is performed on considering the soil hyperbolic stress strain model and incremental iterative nonlinear numerical algorithm. And nonlinear behavior of soil materials in the dynamic analysis is taken into consideration by using the time domain equivalent linear procedure. Finally, it is pointed out that the composite foundation can reform the characteristics of dynamic response of a natural foundation and satisfy the requirements of practical engineering.
