浅谈城市轨道交通小号码道岔设计

A Brief Touch on Small Number Turnout Design for Urban Rail Transit

小号码道岔在城市轨道交通领域占据主力市场 ,在城市轨道交通领域发挥着不可估量的作用。小号码道岔设计应结合城市轨道交通的特点 ,合理地选择未被平衡的离心加速度和线型 ,合理地计算其轨距加宽及解决自身的构造加宽问题。小号码道岔跟端应当向弹性可弯方向发展。小号码对称道岔需要重新认识并重视起来。

Small number turnout holds a major market share and plays the immeasurable role in urban rail transit. In design of small number tu rnout, the characteristics of urban rail transit should be taken into considerat ion, and unbalanced centrifugal acceleration and line type should be properly se lected, and computation of gauge widening and turnout structure widening should be appropriately handled.
