Research on the Interaction Relation of the Causations of Tunnel Collapse Accident

Abstract:

The purpose of this study is to find the key factors influencing the tunnel collapse accident, and explore the causal relationships between the causations of the tunnel collapse accident. Based on document surveys and Delphi Method, a system of the causation indicators of the collapse accident is established. In order to make sure that the hierarchy structure of the causation index system of the tunnel collapse accident is illustrative and reasonable, a new method of system structure analysis is proposed based on the integration of Decision making trial and evaluation laboratory (DEMATEL) and Interpretive structure model (ISM). Applying this method, the center degree and the reasoning degree of the causation are obtained firstly, and then the system hierarchy structure of the causation index system of the tunnel collapse accident is actualized. The results showed that the main causes of the tunnel collapse accident are derived from management. This research reveals the interaction relations of the causations of tunnel collapse accident, based on which this research also provides strong theory and methods to support dynamic decision and quantitative risk assessment in tunnel construction.
