摘　　要：在铁路电气化接触网施工中,接触网下锚安装为一道主要关键工序。往往在车站施工中会出现受地形条件限制,一部分接触网下锚按照一跨设置,从而导致接触网下锚安装高度引起正常悬挂高度不符合设计要求。接触网下锚有一定的抬升量,下锚安装高度与悬挂点存在不等高高差,造成悬挂点会出现上拔力向上力,需要调整下锚安装高度。为解决这一问题,本文主要探讨分析下锚上拔力与悬挂点抬高量的关系。Catenary is an important part of electrified railway.When the anchor falls in contact with the net,there will be a certain lifting amount,which will result in the phenomenon of unequal height between the non-supported lifting point and the anchor falling.There is a large height difference between the two hanging points,and the non-supported lifting point may have upward pulling force.This paper mainly studies the principle of the upward pulling force of the lower anchor.

关 键 词：接触网 下锚 上拔力
