Abstract
In the process of steel rail fine adjustment construction of high-speed railway, if ignoring the process control or paying no attention to the key technologies during static adjustment, the workload and difficulty of steel rail fine adjustment during integrated commissioning will be increased, and consequently the integrated commissioning will be influenced adversely. Therefore, it is very important to master the key technologies of steel rail fine adjustment, in order that the track geometry size can quickly meet the requirement of integrated commissioning. This paper, based on the experience on steel rail fine adjustment for Shijiazhuang-Wuhan passenger dedicated line, in combination with the characteristic of steel rail fine adjustment by the use of track inspection trolley, analyzed the process of steel rail fine adjustment in details. Furthermore, this paper proposed the key technologies which should be mastered respectively in construction preparation stage, construction stage and acceptance stage; and also carried out relevant analysis and verification by using inspection data. It is proved by practice that these key technologies have played significant roles in fine adjustment of steel rail.关键词
