Railway Tunnel Information Construction Management And Forecasting System Development And Application

Tunnel engineering is one of the controlling engineering of mountain railway construction in China,New Austrian method of tunnel construction technology has a history of more than 30 years since promotion. In the engineering construction,people gradually realized that engineering geological survey, design and construction information form systematic and integrated concept is very important.The theory and methods of modern thought that the technical personnel should pay attention to collect the information about the geological conditions and construction conditions before construction, construction process and construction constantly in the construction of tunnel engineering and monitor information through scientific analysis and forecasting, and timely feedback to the design to guide the construction.To reach the purpose of optimizing the construction,the technical personnel introduce the theory of design and construction of informatization.The paper based on the research achievements of predecessors, the informatization construction in tunnel on the basis of the basic theory and method, in order to realize the tunnel construction constraints information management and digital geological logging mainly.And on the basis of monitoring data, through the process analysis, predicting surrounding rock stability and change trend.Development of friendly interface, convenient and practical application, and its application in the tunnel construction in the park is great.Through research, mainly have the following results:(1)Summarizes the theory and methods of traditional information construction, elaborated the basic principle and method of the informatization construction.Content and method of tunnel safety monitoring is introduced, and based on monitoring control standard is established based on the monitoring measurement of tunnel safety forecast mechanism.And, the expansion of traditional information construction content, the constraints of geological survey, tunnel surrounding rock classification, advance geological forecast are also included in the informationization construction category.(2)Using interactive object-oriented program design thinking, Visual Studio 2010 is chosen as the application development platform, SQL Server 2008 for database operation platform, basic theory and methods of the informatization construction in tunnel for the technical system,informatization development of tunnel construction and disaster prediction Web server software, software integration user information management, construction management, the classification of surrounding rock and surrounding rock stability analysis of the main function module.(3)The development environment for Eclipse, JAVA is the programming language, development and design based on the android mobile platform android client tunnel informatization construction subsystem, information query system mainly integrated tunnel profile design constraints and geological record module, using the HTTP protocol and network communication technology, realizing the android client reads and writes data to a Web server system.(4) The system in tunnel construction, the application of the android client terminal system constraints of geological record function constraints can achieve rapidly excavation digital geological logging,and save logging information to upload server management, Web server system to realize the effective management of tunnel construction measurement information,Through the analysis of the characteristics of monitoring data processing to predict tunnel surrounding rock stability of the entire software basic can satisfy the requirement of engineering construction, realize the tunnel informatization construction.
