| 摘 要： | 有限单元技术在地球科学中得到日益广泛的应用,但目前直角坐标下的有限元分析程序处理地球(由于地球的球形)科学问题极为不便。文中利用球坐标下弹性力学的基本方程和有限单元分析的基本方法,编制了球壳有限单元程序,选择中国大陆的主体区域进行了实例计算检验;发现分析方法合理,结果可靠。

| Abstract: | The finite element method (FEM) has found wide application in geo-science. However, FEM, which is applicable only in rectangular coordinate system, reveals great inconvenience when applied to problems in geo-science because of the global shape of the Earth. In this paper, the shell finite element program is coded on the base of fundamental elastic equation and FEM. We took Chinese mainland as a sample area to test the shell FEM, the results of which prove to be reasonable and reliable. |
