Design And Implementation Of Underground Space Information Management System For Geotechnical Engineering Investigation

With the acceleration of infrastructure and urban rail transit construction,the development of underground space resources has been intensified.The underground space data provides the data foundation and basis for the design,construction and operation of the later project.It is an important reference for the administrator to make emergency plan and macro decision.Geotechnical engineering survey as an important source of underground space information,the current data is stored in a single,discrete way,management is inconvenient,easy to lose,and can not comprehensive analysis and statistical calculation of data,do not make full use of data value.As an important data resource of underground space,engineering survey data needs to be efficiently managed,developed and utilized.The rapid development of digital and information technology provides powerful technical support for information management of engineering survey data.Based on this background The establishment of geotechnical engineering underground space information management system came into being.Based on the efficient management and effective utilization of underground space data,this paper studies the organization and management methods of underground space data and data based on exploration holes,and designs and implements the “geotechnical investigation underground space information management system”.The main work and results of this study are as follows:(1)By analyzing the geotechnical engineering survey requirements,it is concluded that the geotechnical engineering survey business process is roughly divided into six modules: creation project,creation outline,outline review,data collection and entry,data processing,and output output.(2)The conceptual model,logical model and performance model of geological survey are studied.It provides a basis and reference for the concrete realization of the underground space information management system.(3)Designed and realized the underground space information management system for geotechnical engineering survey,and completed the realization of functional modules such as project management,data processing,basic database,comprehensive information display,project review and result map.(4)Analyze and implement key technologies such as heterogeneous database data synchronization,four-parameter conversion,and CAD automatic layering.(5)Taking the T2 line of the tram in Shunyi District as an example,the underground space information management system of geotechnical engineering survey was applied.The results of demonstration application show that the geotechnical investigation underground space information management system can effectively realize the standardization and information management of survey data,and can effectively improve the utilization rate.
