有轨电车岔区基础变形研究
Research on Foundation Deformation of Tram Turnout Area
摘要
Abstract
In view of the foundation deformation of No. 6 tram turnout area, the model of turnout area and its anteroposterior boundary effect regions is established with finite element software to study the impact on the cocking-up value of the tip of switch rail by the position of foundation deformation and the amplitude of foundation deformation in turnout area At the same time, the requirement of the limiting value of foundation deformation in case of track slab lift is put forward. With the calculation results of wheel-rail contact geometry of the groove rail turnout, the limiting cocking-up value of the tip of switch rail is analyzed. It is concluded that the limiting value of uneven settlement of subgrade shall not be more than 10 mm/20 m and the maximum cocking-up value of the tip of switch rail shall be 4 mm based on the calculation results of the maximum cocking-up value of the tip of switch rail and the lift of track slab with respect to the subgrade of groove rail turnout.关键词
