【摘要】 土体原生和次生各向异性有本质不同。从柔度矩阵的角度分析了弹性和弹塑性理论对各向异性的反映 ;复杂应力状态下砂土真三轴试验结果表明 ,次生各向异性对土体应力应变关系有很大影响 ,是土体特性的本质体现 ,在土工数值分析中应当充分考虑其影响。更多还原

【Abstract】 There is essential difference between the soil’s inherent anisotropy and induced anisotrophy.The explaination based on elastic and elastic-plastic theory to anisotry is analysed. It can be drawn from the result of true-triaxial test that induced anisotrophy has much influence on soil’s behaviour,so enough consideration should be taken when making numerical analysis on soil.更多还原
