Based on the analysis of adjusting course for Metro Track Laying Control Points,the paper provided a method of metro line adjustment by Microsoft Excel,by which the computation became intuitive and rapid,and the measurement efficiency of Metro Track Laying Control Points was greatly improved.

Foundation pit in open excavation section for intersection of Exhibition Center-Civilian Center and Northwest Liaison line serve meantime as tracklaying base for Shenzhen Metro.

Taking the Qin-Shen line for example,this article gives a description of the technological process of welding & storage of continuous rails in the base,bottom ballast installation,track-laying,field welding,stress release and fastening down of rails and precautions for the construction of one-time CWR track laying on monoblock concrete sleeper

The paper introduces a method of calculating the time limit for track laying and bridge erecting engineering project, in which several factors are quantized.

Research purposes: In cause of innovation of existing railway line, sometimes it needs to lay continuously welded rail in minor section, but it is difficult to do it with long-railed machinery, so the method of replacing and laying track with track panel was adopted previously.
