摘要
利用层状材料的广义Kelvin基本解,建立了计算矿区三维层状地基的应力和位移的方法。将广义Kelvin基本解与边界元方法相结合,建立层状地基边值问题的边界积分方程,方程中不含有层状材料交界面上的积分。对于核函数中出现的奇异积分做了详细的解答。算例分析表明,本文建议的方法可以获得较高的计算精度。
The method for the analysis of layered soil is presented using the fundamental solutions of three-dimensional multilayered solids of diggings, The generalized Kelvin basic solution and the boundary element method coupling, the boundary integral equation is established for the layered soil boundary value problem, and does not include interface integral. The singular integral appearing in the kernel function has made the detailed explanation. It is shown that the present method is efficient for the stress and displacement in layered soil.
