Karst Water Bursting in Railway Tunnel is the main content of tunnel risk evaluation,there are lots of empirical factors in the actual work. Through the investigation on site, this study analyses Karst Tunnel on many respects, establishes the index system of venture evaluation on Karst Water Bursting Geological Disasters. Moreover, the concept of fuzzy information analysis is introduced to establish the fuzzy information analysis model, on the basis of information extraction of a large amount of geological disasters of Karst water bursting in Railway Tunnel, in which applied hierarchy analysis method to determine the weight of each index. Risk assessment on typical operating point shows that the risk evaluation method of fuzzy information can correctly assess the Karst water bursting disasters in railway tunnel.

Sichuan Province of China is a prominent population and economic growth center as well as an earthquake-stricken region. A sound understanding of the seismic risk that Sichuan Province is facing is useful to raise risk awareness, achieve disaster risk reduction (DRR), and guarantee sustainable socio-economic development. Earthquake risk assessment is the first step in these efforts. This study strives to demonstrate the feasibility of applying an integrated earthquake risk assessment in Sichuan Province of China using RISKPLAN, a risk evaluation tool of natural hazards developed by the Swiss Federal Office for the Environment (FOEN). The time and location of seismic events in Sichuan were incorporated into three scenarios and calculated with respect to expected losses under different assumed conditions of earthquake occurrence, such as the recurrence interval and magnitude. Furthermore, cost-effectiveness calculations were made regarding the various possible scenarios to assess the ratio of expected losses and the required financial means for prevention and mitigation measures against the effects of seismic activities in Sichuan. Our results show that when the magnitude of the seismic event is greater than expected, reduction and mitigation investments for a possible earthquake risk will be all the more rewarding.
