Research On Construction Organization And Transportation Organization Optimization For Existing Busy Railway Mainlines

The rebuilding of the existing railway lines for raising train speed purpose can raise transportation speed and shorten traveling time of passengers and goods. It is both needful to adapt developing national economy and improving people's standard of living, and important way for improving transportation quality and standard of service and enhancing competition capability of railway enterprise, which is very necessary for great-leap-forward development of railway enterprise and development of national economy. In course of the rebuilding of the existing busy mainlines for raising speed, the conflict between construction and transportation is very salience. It is very important for go on wheels of construction, transportation, stratagem for raising speed and so on to resolve the conflict.Construction organization optimization transportation organization optimization and coordination of construction and transportation are analyzed. The frame of construction for existing busy mainlines is proposed. The dynamic control system for construction progress is set up. Construction period optimization relevant flow charts are given. The coordination strategies between construction and transportation are proposed. Ideas and ways are supplied by what are said before, which is better to solve the conflict between construction and transportation. The main research contents and functions as follows:1) The characteristic of construction for existing busy mainlines and the influencing factor to construction progress are analyzed, and the frame of construction for existing busy mainlines is proposed. The whole project includes some construction segments, which is consist of some independent branch projects and non-independent branch projects. Some work procedures are involved in the branch project. After the frame of construction for existing busy mainlines is proposed, structure of the whole construction period is made sure, and controlling construction progress is easy.2) Based on the analysis of basic principle and virtues of network technique, the dynamic control system for construction progress is set up, which is made up of monitoring subsystem and adjusting subsystem for construction progress. According to the frame of construction, the relation of whole construction...
