摘要
在重力正演计算中垂直园柱体是一个较为简单,而又有较大实用价值的模型。但至今为止,还无法用解析公式计算出来,这就大大地限制了该模型在重力异常解释中的应用。这里利用效果较好的三角元法来计算垂直园柱体模型,同时还提出了合理的计算方案,编写出较完善的程序,因而获得了高精度的计算结果。
A vertical cylinder is a simple and practical model in gravity forward problem. So far this model can not be calculated by analytical expression, which restricts its application in the gravity interpretation. In the paper the author makes use of the triangle element method to calculate the gravity anomaly of the vertical cylinder and achieve high accuracy numerical results with designing computer program based upon a reasonable algorithm.
