Design of intelligent and integrated information system for shield construction

In order to improve the construction of shield, an intelligent and integrated information system for shield construction is designed. Ground Penetrating Radar(GPR) is installed in shield cutter disc for the first time to explore frontal geology in real time and continuously. Based on the route deviation of shield and the influence of geological conditions on shield construction, a compound intelligent control system with double structure is designed to control shield. The information of construction is integrated and published in order to be shared by all authorized users. This scheme is important to improve intelligence and infomationization of shield construction, which is innovative and valuable for engineering application.
