| 摘 要： | 为解决大角度起伏地形即陡峭地形(如河流阶地、冲沟、堤坝、山谷、山脊等)对实测视电阻率的影响问题,这里优化了三维有限元数值模拟中的单元积分形式,使之适合大倾角地形条件下对电阻率的数值模拟.为验证方法的正确性,采用保角变换计算了相近地形在均匀电流场情况下,陡峭地形引起的视电阻率变化特征.计算表明,对于缓倾斜地形,有限元数值...

| Abstract: | To solve the problems which has the impact on measured apparent resistivity caused by large-angle rugged terrain that is steep terrain(such as river terraces,gullies,dams,valleys,ridges,etc.),we optimize the 3-D finite element numerical simulation of integral unit in this paper,which is suitable for steep terrain conditions to the numerical simulation of resistivity.To verify the correctness of the method,conformal mapping was proposed on calculating the similar terrain of variation characteristics of appar... |
