2) circular lining
圆形衬砌
1.
the amended Biot model considering compression of soil grain and pore fluid and viscid coupling between pore fluid and soil skeleton,and the wave function expansion method are adopted to numerically analyze the scattering problem of a infinite circular lining deeply buried in nearly saturated soil and the dynamic st.
忽略土颗粒的压缩性,考虑孔隙流体的压缩性以及孔隙流体与土骨架之间的粘性耦合作用,采用修正的B iot模型,运用波函数展开法研究了平面P1波入射时,准饱和土体内深埋圆形衬砌的散射问题,通过数值计算模拟并分析了衬砌的动应力集中问题,结果表明:不论入射频率为低频(100Hz)还是高频(500Hz),对于相同的衬砌,当土体为准饱和时,动应力集中因子沿周向分布曲线的形状和数值基本保持不变;但土体为完全饱和时,虽然饱和度发生了微小的变化(比99%只提高了1%),但动应力集中因子的值却大幅度地降低,其沿周向分布曲线的形状也发生了显著的变化,在工程设计中应重视饱和度对圆形衬砌动应力集中因子的影响。
