摘要
本文将加筋复合土体视为一种近视的横观各向同性体,引入摩擦等效附加应力的概念来模拟土与加筋体之间复杂的界面作用,充分考虑复合土体的各向异性以及土工合成材料的受力变形特点,得到一个加筋复合土体的本构关系,在不同的受力和变形条件下应采用不同的计算公式,本模型可用于加筋结构的研究分析之中。
The reinforced soil is regarded as a crossanisotropic and macroscopically homogeneous composite material.The concept of friction equivalent additional stress is introduced to simulate the interfaial action between soil and veinforcement.In consideration of the anisotropic characteristics of reinorced soil the constitutive relationship of reinforced soil is established and the formulas for calculation are proposed.
