Research and Optimization of Track Vibration Prediction of Ningbo Rail Transit
摘要
Abstract
In the vibration-reduction design of underground track at preliminary design stage of urban rail transit, the reconnaissance, engineering analogy and other empirical methods are often adopted to address the environmentally sensitive points within the range of 10~60 m away from the outer rail on both sides of the center line, which may have a certain error. Based on vibration-reduction model of Guidelines, this paper is to study the vibration-reduction methods applied to underground track of Ningbo rail transit with reference to the experiences of Beijing, Shanghai and other cities, and use computer language to fulfill programmed prediction model for better design efficiency. At the preliminary design stage, standardization and automation of vibration prediction play an important rule in stabilizing track structure height, and specifying investment budget, and reducing repeated design.关键词
