摘要
在采矿及其它岩土工程中遇到的大量岩体呈明显各向异性。本文以各向异性弹性理论为基础,采用富氏变换导出了横观各向同性复合半平面问题的虚应力边界元法,并与其它算法进行了比较,验证了该算法的正确性及优越性,并以一应用实例说明了它的实用性。
Most of the rock masses encountered in mining and geotechanics engineering are anisotropic bodys. In this paper, transversely istropic bound-half plane problem with the ficti- tious BEM is reported by using Fourier integral transformation. The validity of the method is verified by the two transversely istropic interface method and others. A application example is gived to verify it's validity. The results verified the advantage of simple boundary discretiza- tion, less data preparation.
