Abstract
For the geological risk assessment of intermediate underground condition by excavation work, since rocks and geologic structure of each country is different, it is necessary to objectify or classify quantitatively intermediate underground risk evaluation in accordance with Korean geologic characteristics. It could be summarized major factors of rock failure and ground subsidence by geological and geotechnical features as overburden, ground characteristics of soil and rock, geologic structures, hydrogeology, high stress, and artificial structures. Induced main factors that could be identified and predicted intermediate-depth tunneling risk through literature investigation and analysis study on research trend related to the deep to intermediate underground geological engineering. It might be classified major factors of intermediate-depth tunneling risk by geological features. These factors affect differently each other in accordance with a type of ground condition that classified rock, groundwater, high stress, artificial structures, and complex.
