摘要
本文采用边界元法求解了文克勒及弹性半空间体两种地基上的板,并对弹性半空间体地基上开孔板、梯形板进行了计算分析。计算结果表明,边界元法具有精度高、计算速度快、占用计算机内存少等优点,是水泥混凝土路面应力分析的一种可行的数值计算方法。
In this paper the Hankel's transposition solution of infinite plates onelastic foundations is applied for kernel function of boundary elementmethod(BEM).The plates on Winkler and elastic halfspace foundationare solved dy BEM.The trapezoidal plate and the plate with a hole onelastic halfspace foundation are analysed.The computed results provethat BEM have the advantage of high precision,rapid computing spe-ed and less storages of computer occupied.It is a feasible numerial computing method of stress analysis of cement concrete pavements.
