The geological disposal of radioactive waste is a complicated system engineering that involves many disciplines,such as, radiochemistry, atom physics, geohydrology, hydrogeochemistry, tectonic geology and civil engineering. The geological work is very important in the geological disposal of radioactive waste because the main body engineering of the warehouse building is geological engineering. Based on literature survey and the author's experience ,this paper introduces the research content and the research scope and its situation of the geological disposal of low and intermediate-level waste and the high level waste,all of are significant, including geologic structure geohydrology ,hydrogeochemistry, earth physics ,mineral & rock ,engineering, and geology hazard .
