本文简单介绍边界元法的原理,并讨论了在IBM-PCXT微机上编制边界元程序的若干问题。给出了包括应力自动绘标在内的完整程序。用此程序及所建立的一系列模型,分析了刘冲矿地压重点防范区中的-90米、-180米中段,以及T547勘探线各剖面模型的应力分布和位移分布。本文指出,应用此程序(或程序包)能够十分方便地给出工程问题的满意解答。
This paper briefly introduces the principle of boundary element method and discusses some problems in compiling boundary element programs on IBM-PCXT microcomputer. A complete program including automatic stress plotting is given. Using this program and a series of models established, the stress distribution and displacement distribution in each section model of the T547 exploration line are analyzed in the mid-90-meter and mid-180-meter sections of the key pressure zone of Liuchong Mine. This paper points out that the application of this program (or package) can be very convenient to give a satisfactory solution to engineering problems.
