In the tunnel construction, due to the limitation of the survey and design and the complex dynamics of tunnel surrounding rock geological conditions, so it is difficult for complex geology with the microscopic accurate grasp, often which caused by geological exploration data do not tally with the actual situation, often encountered in karst water inrush, large deformation in weak rock, cave-in ...

Based on the precipitating factors of geological disasters in complex mountainous regions, this paper took geological disaster distribution, seismic intensity, fracture, engineering petrofabric, river distance, slope and precipitation as the risk indicators of geological disasters. Next, a mathematical model was established by using the analytical hierarchy process. The weight of above seven ri...

National geological survey works have characteristics of data enormousness, computing denseness, resource distribution, and applications heterogeneousness. As innovative information infrastructure and service architecture, grid can meet geological survey application requirements by implementing sharing and cooperation of distributed and heterogeneous resources. Based on grid technologies and OG...
