摘要
以植生混凝土为研究对象,采用离散单元法,通过Fish语言编写了二维不规则骨料的植生混凝土虚拟试件开发程序,建立了植生混凝土的数值模型,分析了数值试验中的应力-应变、体应变、裂纹数以及能量响应的变化规律。结果表明,基于离散元理论和PFC2D程序能够有效地模拟植生混凝土在单轴压缩状态下裂纹的生成、扩展以及破坏的全过程,为进一步研究植生混凝土的破裂机理奠定基础。
To study the Green -Growing concrete , The DEM is used , a program for two -dimen-sional virtual mecha nical simulation of Green -Growing concrete with irregular particles is written by fish language , the green-growing concrete model was built , and the Developments of stress -strain relationship , bulk strain , crack numbers and the energy response are analyzed in details.The results show that the formation and development of cracks and the whole process of fragmentation can be ef -fectively simulated the green -growing concrete under uniaxial compression condition Based on dis-crete element method and the code PFC 2D and lay the foundation of further studying the fracture mechanism for Green-growing concrete.
