[Abstract]:This paper tries to integrate and integrate virtual reality technology, which has gained value, significant cost, BP neural network, grey system and other theoretical methods, and through the development and application of virtual dynamic optimization management software system, the virtual visualization tube of the engineering period, cost, quality, environmental protection and safety of the Bazhong municipal infrastructure project is carried out. In order to improve the economic and social benefits of the construction management of municipal engineering projects, the main contents are as follows: first, the virtual static target optimization management system for tunnel construction is established. Before construction, according to the construction characteristics and technical requirements of the highway tunnel engineering, it is based on the extensive collection of various types of work, professional technology, construction and management data. By using BP neural network, grey theory, VR virtual technology, PERT network technology, cS significance theory and other technical methods, the virtual static target optimization management system of multi types of highway tunnel engineering, multi professional interface, cooperative and three-dimensional cross operation is established. Secondly, the virtual dynamic optimization management system for tunnel construction is established. In the construction process, EVM is used in the construction process. The value theory, the PDCA cycle management, the CS significance theory and the PERT key line method, the virtual technology and so on, establish the virtual dynamic optimization management system. The manager can grasp the project situation directly and vividly, analyze the problems and causes in the construction in time, predict the possible problems, and formulate the pre control measures. In order to ensure the construction period and reduce the cost, the hidden dangers and problems are eliminated in the sprout state by optimizing the construction process by the loop. Through the practical application and operation of the above system, various management optimization schemes can simulate the visual image on the virtual map in advance, and provide the advanced decision-making platform and means for the managers. In the course of construction, the management layer of the project can be at any time, through the virtual visualization system of the computer, the problems that should be carried out in the next stage, the problem of the time cost to be solved and the pre control measures to be taken are clear, and the visualization of the project management is realized, which greatly improves the efficiency and the level of the tunnel construction management.
