为了研究工程中常用的短垂直接地体的降阻性能,对雷达等小型军事阵地接地网进行了仿真研究.对于均匀土壤,从布置位置和安装根数两个方面分析了短垂直接地体的降阻效果.对于双层土壤,从反射系数、上层土壤厚度研究了短垂直接地体的降阻效果.研究结果表明,短垂直接地体对小型接地网具有一定的降阻效果,布置在接地网边缘时降阻效果最好;在双层土壤中,短垂直接地体降阻率随反射系数的增加而明显减小.这对接地工程有一定的参考价值.

In order to study the resistance-reducing effect of the short vertical grounding rod commonly used in projects, this paper performs on the simulation study for the grounding grids used in the radar and other military positions. In terms of such two aspects as the layout location and mounting number, for the uniform soil, and in view of the reflection coefficient and the thickness of the upper layer of soil, it studies the resistance-reducing effect of the short vertical grounding rod, for the two layer soil. Research results show that the short vertical grounding rod is of a certain resistance-reducing effect on the small ground grids and have the best effect when the rod is mounted to the edge of grounding, the resistance-reducing rate decreases clearly as the reflection coefficient increases in the two-layer soil, which provides some reference for the grounding project.
