摘　　要：为了更好地进行地基沉降预测,介绍一个简易计算方法—双曲线模型法.该方法采用双曲线函数来反映地基沉降的非线性,且提出通过原位土压板载荷试验来确定模型参数,从而避免因地基土体采样扰动造成的参数误差.将其应用于某筏板基础沉降计算中进行验证表明:模型计算结果与实测结果较吻合,即原位土双曲线模型法用于地基非线性沉降计算是可行的.In order to better predict the settlement of foundation,a simple calculation method-hyperbolic model method was introduced,in which hyperbolic function was used to reflect the nonlinearity of foundation settlement,and in order to avoid the parameter error caused by sampling disturbance of foundation soil,in-situ soil plate loading test was proposed to determine the model parameters.This method was applied to the settlement calculation of a raft foundation.The results showed that the model calculation results are in good agreement with the measured results,which proves that the in-situ soil hyperbolic model method is feasible for the nonlinear settlement calculation of foundation.
