| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 100 === The way we deal with nuclear waste must be careful. We
have to make sure that nuclear waste do not release to the
biosphere. There are many researches for this topic. In the case of high-level radioact ive nuclear waste, deep geologic disposal is the most secure measures to deal with. And the low-level radioactive nuclear waste is placed to the shallow land disposal.
This research is reference Dong Chen, 2006. We consider
that concrete structures are affected by various deteriorat ions,and use ABAQUS finite element software to do the analysis of coupled thermal–hydration–carbonation.
This study focuses on the spatial and temporal
distributions of temperature, relat ive humidity and carbon
dioxide concentrat ion in heat transfer, hydration and
carbonation. We also analyze the deteriorat ions of concrete
porosity, and know that hydration and carbonation influence
each other greatly.
