| 摘 要： | 对于残积土地基的沉降变形，实践证明采用压缩模量的计算结果往往偏大，应采用现场试验得到的变形模量来进行计算。为此，该文以广州某残积土地基的实测资料为例，对其非线性沉降采用双曲线模型来表示，所需计算参数则根据现场载荷试验来确定，最后将计算结果与试验结果进行对比。结果初步表明，双曲线模型法用于残积土地基的沉降计算是可行的。 |

| Abstract: | For settlement deformation of residual soil foundation, it is proved that the calculation result of settlement is often too large when using compression modulus and it should use the deformation modulus obtained by field test. Therefore, some measured data of a certain residual soil foundation in Guangzhou were taken for an example in this paper, in which the nonlinear of settlement was expressed by hyperbolic model and the required calculation parameters were determined according to the field loading test, and finally the results were compared with test ones. The comparison results show that the method of settlement calculation with hyperbolic model for residual soil foundation is feasible. |
| Keywords: | hyperbolic model residual soil foundation settlement nonlinear field loading test |
