Study On Integrated Information Management Of Maanshan Highway Bridge Over The Changjiang River

Large-scale expressway engineering project has complicated techniques, long construction period, many construction units, short project time, heavy task character, etc. That each unit does things in his own way and information was passed difficultly in traditional project management couldn't meet the requirements of modern construction, Construction project management model has been imperative to reform. How to make construction information pass in time and exactly, improve management level and efficiency has become more and more important.Modern computer and IT technology develop quickly, which offer chance for information management. Internal and overseas institution have studied on this partly, but overseas information management software has difference with our highway engineering character, need to be continuous researched. Internal software has the same problem that it couldn't satisfy construction needs, the correlation of each subsystem or function module was poor, integration and extension was in-depth enough.This thesis demonstrates that Maanshan bridge project has important conditions for integrated management from common idea and advanced information technology, combined with the actual situation of Maanshan bridge, brings forward the three-integration dimensional structure of project management, expatiates what are organization integration, process integration and element integration from logic dimension, time dimension and knowledge dimension, and reveals the internal relations between the three kinds of integration.Basing on traditional project management theory, this thesis brings forward a dominating management concept that is all technicians Participate in the whole process control, emphasizes the process control and management. The owner carries out regular quality and security inspection and comprehensive inspection to ensure the project quality and security. Inspection takes table format, which is to improve the efficiency of the inspection and reduce capacity needs of the inspectors. At the same time, information theory is applied on management, through establishing information processing group, the owner realize that information is collected, processed, maintained and used in time, reflects that management is active, forward-looking, timely and accurate.This thesis also brings forward fuzzy division principle and lean construction principle, indicates that modern project management is no longer a problem in the traditional sense of "either-or" relationship, but is "he has also" in the middle of the state, has shown an increasing trend of fuzzy, stresses that fuzzy division can play integrated effect fully between sectors and departments, points out lean construction can bring greater economic benefits with less investment costs.For realizing the above-mentioned project management ideas, the thesis puts forward using Manshan bridge web site as management platform, video surveillance subsystem and processing subsystem as supplementary means firstly, which form the integrated information management system of the Maanshan bridge. All units can share and exchange information with integrated information management system, realize information management and integrated management, enhance the management level and efficiency effectively.
