摘要
利用有限元方法系统地研究了机车、罐笼、金属支护立柱等长列金属物体对井下规则隧道中电磁波截止频率的影响,可知长列金属物体的存在使TE波模截止频率降低,而使TM波模截止频率升高.相比较而言,罐笼对电磁波截止频率影响最大,支护立柱影响最小,机车对电磁波影响的范围最大.
Using finite-element method the effects of long objects, such as cage, train and metal pit prop, on electromagnetic wave cutoff frequency is researched systematically in regular tunnels, and it is shown that the long metal objects lower TE wave cutoff frequency and raise TM wave cutoff frequency. Comparatively, the effect of cage is more than that of pit prop.
