- Abstract
In order to solve the matching problem between the route of the additional third and fourth line in the lines paralleled section of the comprehensive railway hub and the existing railway, municipal road, high-rise building gathering area and other factors, based on the investigation and design examples, combined with the major demolition gathering areas, several high-speed railways and municipal roads along the line, the research was carried out from the aspects of the determination of the mileage of the existing lines, the overall route selection ideas, the key and difficult engineering schemes of the line, and the plane calculation methods. The research results show that, the switch rail tip could be used as the basis for determining the mileage of the existing line, the reference line in the lines paralleled section should be re-determined as well as the mileage of the adjacent line; The additional third and fourth line should avoid major demolition by constantly changing the position. The municipal roads near the high-rise residential areas shall cross the existing railway considering better urban landscape and less the noise pollution; The minimum line spacing should be adopted in the straight section of the line section. The curve widening is generally completed by lengthening the length of the transition curve of the inner side line. The line spacing should be increased only under limited conditions. The straight-line variable distance and curve variable distance are applied to avoid piers and single buildings and the side changing of the curve and straight sections are applicable to avoid demolition gathering areas along the existing line.
