为解决目前考虑位移土压力计算方法中参数不易准确取值的不足,在传统的双曲线土压力计算模型和邓肯-张本构模型推导方法的基础上,建立了加固护岸板桩土压力计算模型,提出了基于弹性半空间的Mindlin位移解的土体横向基床系数解析解法。算例分析结果表明,理论计算值与数值模拟值基本吻合,最大仅相差7.6%,从而验证了双曲线土压力计算模型及土体横向基床系数的解析解法合理、可行。 In order to solve the shortcomings that the parameter of displacement earth pressure calculation is not easy to get accurate at present, on the basis of the traditional hyperbolic earth pressure calculation model and Duncan-Chang constitutive model derivation method, the earth pressure calculation model of reinforced revetment plate is established. Analytical Solution of Soil Subgrade Bed Foundation Coefficient Based on Mindlin Displacement Solution in Elastic Half Space. The results of the example analysis show that the calculated values ​​are in good agreement with the numerical values, and the difference is only 7.6% at the maximum. This verifies that the analytical model of the earth pressure on hyperbolic and soil bed coefficient is reasonable and feasible.
