摘　　要：研究了青藏铁路冻土区的土壤结构,给出该地区的典型土壤模型;通过计算机仿真分析,针对不同深井的个数与深度对接地系统降阻效果的影响,分析了三者之间的相互关系,研究出青藏铁路的深井接地方案。In this paper, the soil structure of Qinghai-Tibet railway frozen ground district was analyzed and the typical soil model was given. By computer simulation, considering the effects caused by different number of deep-well and its depth, the deep-well grounding plan of Qinghai-Tibet railway was worked out.
