中俄高速铁路有砟道床技术条件分析——时速350km高铁设计参考与借鉴
Technical Analysis of Chinese and Russian High-speed Ballast Bed-references for 350 km/h HSR Design
摘要
Abstract
To clarify technical differences and their inherent causes between Chinese and Russian high-speed railway ballast bed, this paper analyzes the design codes and technical conditions of high speed railway ballast bed of different gauges in China and Russia with reference to Moscow-Kazan high-speed railway and Beijing-Zhangjiakou 350 km/h HSR. The following conclusions are reached in view of the influences of the gauge and temperature:(1) ballast bed slope of 1 : 1. 75 and zero shoulder ballast height should be taken, the thickness of ballast bed should be 35 cm, and the thickness of 30 cm could be used for bridge and tunnel sections, for ballasted track with asphalt subballast layer, or where elastic sleeper is used;(2) according to high-speed ballasted railway experiences in Europe, longitudinal resistance should no be less than 14 kN per sleeper and lateral resistance no less than 12 kN per sleeper to satisfy the operation at 350 km/h;(3) measures and precautions shall be taken to prevent ballast flight for speed over 350 km/h;(4) sleepers for 350 km/h by be redesigned in form and dimension, sleeper length of 2. 7 m for Moscow-Kazan railway and 2. 6 m for Beijing-Zhangjiakou railway are recommended.关键词
