摘要

本文研究了非均质土工材料介质被圆形刚性板压进时的接触问题。刚性板受绕水平轴施加的力矩。采用n层半空间模型分析非均质土工材料半空间。利用经典的积分变换和第二类Fredholm积分方程，导出了n层半空间模型的数学表达式。采用数值方法对所提出的分析模型进行求解。数值验证表明，分层方法对深度弹性常数为任意变的非均质半空间接触问题能提供精确的解。数值结果揭示了土工材料非均质性对圆形刚性板上非均质介质在反对称载荷作用下弹性场的影响。

Elastic fields for a heterogeneous geo-material medium under antisymmetric indentation of a circular rigid plate

This paper examines the contact problem of a heterogeneous geo-material medium indented by a circular rigid plate. The rigid plate is subjected to an applied moment about a horizontal axis. An n-layered half-space model is employed to analyze a heterogeneous geo-material half-space. The mathematical formulation of the n-layered half-space model is derived using classical integral transforms and a Fredholm integral equation of the second kind. Numerical methods are developed to solve the proposed analytical model. Numerical verification demonstrates that the layered approach can provide accurate solutions for the contact problem of the heterogeneous half-space with arbitrarily variable elastic constants in depth. Numerical results reveal the influence of geo-material heterogeneity on the elastic field of a heterogeneous medium under antisymmetric loading on a circular rigid plate.
