摘要
利用层状材料的广义Kelvin基本解,建立计算三维层状地基中应力和位移的边界元方法。将广义Kelvin基本解与边界元方法相耦合,建立层状地基边值问题的边界积分方程,方程中不含有在层状材料交界面上的积分。对核函数中出现的奇异积分进行解答。算例分析表明,建议的方法可以获得较高的计算精度。
The boundary element method for the analysis of layered soil is presented using the fundamental solutions of three-dimensional multilayered solids. The generalized Kelvin basic solution and the boundary element method coupling, the boundary integral equation is estabhshed for the layered soil boundary value problem, which does not include interface integral. The singular integral calculus appearing in the kernel function is made solution. It is shown that the present method is efficient for the stress and displacement in layered soil.
