Design And Implementation Of Information Management System Of Rail Transit Engineering Survey

With the acceleration of the construction of urban rail transit,the survey institute of Beijing urban construction exploration and surveying design research institute has intensified the development of underground space resources,and its production scale has been expanding and the number of projects has been increasing.The data of underground space provide the data base and basis for later engineering design,construction and operation,and it is an important reference for managers to make emergency plans and macro decisions.As an important source of underground space information,survey data are kept in an irregular and relatively scattered way at the present stage,which is inconvenient for management and easy to be lost.Besides,it is impossible to conduct comprehensive analysis and statistical calculation on the data,and the value of data is not fully utilized.Rail transit engineering survey data as an important data of the underground space resource,is an urgent need to get the efficient management and exploitation,the rapid development of digital and information technology for information management of engineering survey data provide strong technical support,based on this background,geotechnical engineering information management system for underground space arises at the historic moment.After fully understanding the actual business needs of the survey institute of Beijing urban construction exploration and surveying design research institute,based on the reality,the research and development of the rail transit engineering survey information management system,greatly improve the survey and production efficiency.The main work of this dissertation is as follows:(1)Designed and implemented the survey information management system of rail transit engineering,realized the whole process of survey production paperless office and information management of underground space data,improved the production efficiency of the survey institute and standardized the production process.(2)In view of the problem of data transmission between different types of database systems on the client and server side,the data synchronization technologybetween heterogeneous databases is adopted,the timestamp method is used as the data capture method,and JSON is used as the data transmission format to realize the data synchronization..(3)In view of the actual need of three-level audit of survey report in the process of survey and production,combined with workflow technology,an audit model of survey report was established,and a path selection strategy was proposed to realize full automation of audit.(4)In view of the practical need of the subsequent establishment of three-dimensional geological model of the system,with the help of visualization tools,the generalized triangular prism is used as the basic body element,and the ordinary Kriging interpolation algorithm is used as the method of image smoothing to realize the function of 3D geological modeling.
