A one dimensional geosynthetic reinforced foundation model with non linear spring support

本文推导出一个代表软土双曲线弹簧支撑的土工布加筋基础一维非线性模型。该模型的数学形式是两个非线性二阶常微分方程组。给出了解常微分方程组的迭代格式，并着重讨论了非线性弹簧参数对加筋基础的沉降和土工布拉力的影响。

This paper presents a one dimensional geosynthetic reinforced foundation model with hyperbolic spring support representing non linear soft soil reaction.The mathematical expressian of this model is a set of two non linear ordinary differential equations.A finite difference iteration procedure is suggested for solving these two differential equations.This paper focuses on the influence of one normalised parameter in the normalised hyperbolic equation for springs on the settlement and mobilised tension force in the geosynthetics.The suggested model may be used as a basis for considering more complexities such as elasto plastic behaviour of sand and elasto plastic interface behaviour between the geosynthetics and the sand.
