城市轨道交通换乘车站杂散电流防护与接地方案研究

Study on the Method of Stray Current Protection and Grounding of Urban Rail Traffic Transfer Station

由于新版地铁设计规范对杂散电流防护与接地条款的重大修订,使城市轨道交通换乘车站的相关设计产生了诸多问题。论文通过对新旧规范的深入解读,结合实际工程设计经验,对杂散电流防护与接地提出了同期和分期2种建设形式的设计方案,并对这些方案进行了深入的分析,最终给出适应各种类型换乘站的设计方案,在工程实施便捷的前提下,达到安全、可靠的目的。

Due to the key modification of items about the stray current protection and grounding in the new metro design code comparing to the old, many problems are caused in the relevant design of urban rail traffic transfer station. After deep interpretation of the old and new code together with the practical project design experience, a design method about two construction types which is the same period and the separated period is given on the stray current protection and grounding. These methods are thoroughly studied. At the end, a design which is applicable for all kinds of transfer station is given. It can guarantee safety and be reliable under the condition that it is convenient for construction.
