Abstract:

We mainly made a design and implementation of construction monitoring geology and geographic information system for underground engineering (MGGIS). First, we analyze the characteristics, the structure，the function, the platform and the related technologies and define the access format for data to obtain and store. After that, we present a detailed design and implementation of three functional independent subsystems respectively: working processes project display, flat space-time effect and cross-section diagram subsystem. This is as far as we know the first proposition to use B/S framework geographic and geologic engineering information system for underground construction features via RIA technology. The scheme proposed can display the precise spatial information of changing environment in the construction of underground engineering，which is appropriate to the risk management of underground construction. With the advantage of being easy to use, interactive and fast running, our system is superior to old types of geographic and geologic information system. The achievement of our research has been used in Beijing Rail Transit Project Security Risk Monitoring System, Nanjing Metro Project Security Risk Monitoring System and other related projects.
