Abstract:

The construction process of a NATM tunnel consists of geological data logging and rock mass classification, monitoring of the changes of rock strain and stress, as well as blasting and excavation. Nevertheless, the disadvantages of traditional manual recording of tunnel-related information are: 1) it is difficult to record data in the poor jobsite environment, 2) the storage of these data is very poor, 3) it is not easy to analyze these data to provide more in-depth information to the construction process. This paper adopts decision support system (DSS) to establish ""The Integrated Rock Tunnel Data Logging and Decision-aid System (RTLD)."" The system consists of database subsystem, decision module subsystem and dialog subsystem. The system has a convenient decision-aid interface and an integrated data structure that encompasses all the tunnel-related information. The functions of the system include geological data logs (through semi-automatic image processing), 3D geology prediction, rock mass classification, rock monitoring data recording and graphical display, data recording and display of construction process and resources, and data correlation analysis.
