我从大学里接触铁路路基开始,从事于路基工作至今已四十多年。在这段漫长的岁月中,我作过铁路新建工作,也作过铁路养护维修工作。在这些工作中,由于随时会受到环境的影响,认识有所侧重,感情有所偏爱,这是在所难免的。如今事过境迁,有充分时间来思考铁路路基的过去与未来,由近半个世纪的发展情况,尝试探讨路基技术进步的客观规律, I have been in contact with the railway subgrade at the university for over 40 years now. In this long period of time, I made new railway construction work and railway maintenance and repair work. In these efforts, it is unavoidable that we will be influenced by the environment at any time and we will have a more focused understanding and a preference for our feelings. With the passage of time, there is sufficient time to think about the past and future of the railway embankment. From the development of the past half century, we have tried to explore the objective laws governing the progress of subgrade technology.
