超重载大坡度轨道系统钢轨与扣件选型及其稳定性研究
Research on the stability and selection of rail and fastener of super heavy load and large slope track system
摘要
Abstract
Taking the dam slide of Zhexi hydroelectric power plant as the engineering background, track stability was studied in this paper through field investigation, theoretical analysis, laboratory tests and numerical simulation. The influence of key factors was discussed, including super axle load (57.5 t), steep slope, low speed and etc. The suitable track form, as well as distribution and selection of fastener was put forward. The results of the study can provide reference for the related technology of heavy haul railway construction.关键词
