| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 100 === Disposal of nuclear waste has been the nuclear issues of national concern. As the long term the used nuclear waste produced by the decay heat will have an impact on our environment, countries for the processing of used nuclear waste in the future tendency of deep geological disposal method as final disposal facilities.
Due to the frequent earthquakes in recent years, therefore earthquakes arising out of the fracture will cause stress and pore pressure of deep geological disposal sites around greater change in increments, this research is carried out under the concept analysis.
This study use finite element method by thermo-hydro-mechanical analysis of the effect starting for the disposition of spent nuclear waste produces decay heat of heat analysis, observation on the temperature field conditions change over time.
For the thermal stress analysis, this study uses multiple sets of different size by sequentially coupled thermal-stress analysis of fracture, use effective stress theory to differentiate the actual stress of pore water and host rock.
