在现有研究的基础上，可以用正弦，指数或双曲线函数来模拟松弛应力，挤压应力与位移之间的关联。从双曲线函数这一方面入手，通过水平基床系数结合邓肯-张模型确定公式中参数，建立了考虑位移非线性影响的主动与被动土压力计算公式。该公式简单易懂，物理含义明确，能够反映位移对土压力的非线性影响，具有较好的可计算性，能够很好的模拟出支护结构土体位移的情况。

On the basis of existing researches,the sine,index or hyperbolic function is adopted to simulate the slack between relaxation stress,compressive stress and displacement. By using the hyperbola,this paper estab-lishes calculation formula of active and passive earth pressure under the influence of the nonlinear displacement through the horizontal foundation coefficient of sub-grade reaction combined with Duncan-Zhang model to de-termine the formula parameters. The formula,which is easy to understand and has definite physical meaning with great computability,can reflect the nonlinear influence of displacement on active and passive earth pres-sure and simulate better the situation of soil displacement of retaining structure.
