摘要
ANSYS求解均匀土层在圆形均布荷载作用下,非均匀土层弹性模量E按指数函数表层位移沉降的数值解,并与层合板模型(N=18)得到理论解进行对比,数据达到足够精度。进而继续求解了非均匀土层在不同弹性模量比值情况下的表层沉降分布。应用ANSYS求解在圆形均布荷载作用下非均匀土层的弹性模量E分别按照余弦函数、线性函数、指数函数变化时的表层位移沉降。
For comparison, we obtained the results by the finite element method and the piecewise multi-layered method, when the Young's modulus of non-homogeneous soil layer varied as exponential law. The results of the finite element methods are in good agreement with those obtained by piecewise multi-layered. By using the ANSYS software, the surface settlement of non-homogeneous soil layer with the Young's modulus varies as different kinds of functions were calculated, when remaining the stiffness of the soil layer surface and half space unchanged. We found that the varying of elastic modulus of non-homogeneous soil layer has a great effect on the surface settlement.
