1 前言 广深准高速铁路建设是我国铁路建设发展史上的转折点,使我国铁路技术水平上一个新台阶。为我国发展高速铁路提供经验和设计参数。广深准高速铁路路基填筑于1993年6月底前全部施工完毕,1994年底开行准高速(160km/h)旅客列车。其中包括长约25km,速度200km/h的高速试验线。广深线要求一次铺设无缝线路,路基必须提高设计标准和采取有效工程措施,以满足准高速的需要。
1 Introduction The construction of the quasi-high-speed railway in Guangzhou, Shenzhen and Shenzhen is a turning point in the history of the railway construction in our country and will make our railway technology level to a new level. For China’s development of high-speed rail to provide experience and design parameters. The complete construction of the subsoil of Guangzhou-Shenzhen-Zhunhuo Expressway subgrade was completed by the end of June 1993, and the passenger train at the quasi-high speed (160km / h) was launched at the end of 1994. Including about 25km, speed 200km / h high-speed test line. Guangzhou-Shenzhen line requires a laying of seamless lines, subgrade must improve the design standards and take effective engineering measures to meet the needs of quasi-high-speed.
