为模拟层状矿体开采,本文将四极奇解的概念推广到了直接边界积分法,采用二次形函数表征单元上的插值函数,取得了满意的结果。
In order to simulate the stratigraphic orebody mining, this paper extends the concept of quadripole to the direct boundary integral method, and uses the quadratic form function to represent the interpolation function on the element, and obtains satisfactory results.
