  A Study on Planning of Network-Based Rock Mass Classification and Decision Making System

  Ground assessment processes based on face mapping are closely related to the stability and economic feasibility of NATM tunnels while the expertise of field engineers is a highly important factor. In Korea, tunnel collapse accidents and economic losses have continued to occur due to technical, economic, and institutional problems during NATM tunnel construction. Such problems have led to questions on stability and economic feasibility issues involving domestic tunnel construction. In view of such situations, this study presents methods for building systems allowing speedy and objective rock mass classification and decision making to solve those problems. What this paper proposes is a network-based rock mass classification and decision making system in the form of convergence of construction and IT industries. The expected outcomes of such management models include supporting economic and safe tunnel construction.
