Study On The BIM Optimization Management Of The Time And Safety About Fuzhou Subway Construction Over Wu Long River Interval

Fuzhou subway line 2 over wulong river interval has complex geological conditions. The cross operation between each working procedure is very busy and with difficult construction. The construction management has the remarkable characteristics of the complex system. The complex system problems only by using the control theory and method of complex system can effectively solve and management. This paper intends to use dynamic optimization management technology and combining domestic and foreign advanced BIM virtual visualization technology. Making the schedule management and security management of the project can be visualized display in three dimensional spaces. And take measures timely to control the potential problems through the database.This paper mainly includes the following contents: Firstly, the research on dynamic optimization controls technology of shield tunneling period. Through the comparative analysis, the type of shield machine is optimized, so as to improve the net tunneling speed of the shield machine. In the way of how to speed up the progress of the shield tunneling,to determine the target of the utilization rate of man-hours of the shield machine, finding methods and measures to improve the utilization rate of man-hours of the shield machine. Combined with BIM technology,make the dynamic optimal control of the shield tunneling construction period.Secondly, the research on dynamic optimization controls technology of safety management of the subway construction. Through collect subway construction safety accident types and preventive measures of the relevant information, sorting out the subway construction safety accident classification and prevention table. Combined with BIM technology, make the dynamic optimal control of the subway construction safety management. At the same time, in accordance with the occurrence of major accidents, minor accidents and signs of accidents, establish safety management and early warning system according to the "Hayne law". At last, the application of BIM dynamic optimization management software system is carried out. Subwayconstruction BIM dynamic optimization management software system includes three parts: The first is the engineering construction plan and the project management dynamic visualization. The second is the optimal control of the dynamic visualization of schedule management. The third is the optimal control of the dynamic visualization of safety management. Using BIM dynamic optimization management software system to input data and analysis, and then directly reflect the dynamic control of construction period and safety in subway engineering construction.BIM dynamic optimization management make each of the management layer of the project control the engineering intuitively at anytime and anywhere. Combined with dynamic optimization management theory, to discover the problems existing or may existing in the construction.Timely making and taking preventive measures, so as to improve the project management efficiency and level, to ensure the realization of the period and safety goals of the subway construction.
