高速道岔精调是道岔精度控制的关键环节,高速道岔精调质量决定高速列车运行的安全性、平顺性、舒适性。京津、武广、郑西等高速铁路无砟轨道建设实践表明,高速道岔施工精度无法满足高速列车安全、平稳、舒适、高速的运行要求,必须在联调联试之前及联调联试期间进行全面的轨道检测和精调。
High-speed turnout precision adjustment is the key to turnout precision control, high-speed turnout precision tuning of high-speed train running safety, ride comfort. The practice of ballastless orbit construction of high-speed railway in Beijing-Tianjin, Wu-Guang and Zheng-West shows that the construction accuracy of the high-speed switch can not meet the requirements of safe, smooth, comfortable and high-speed operation of high speed trains. Conduct comprehensive orbit detection and fine tuning.
