| Abstract: | In order to explore the basic physical characteristics and mechanical properties of the surrounding rock in the pre selection area of high-level radioactive waste clay rock in yingejing depression, Bayingobi basin, Inner Mongolia. Through physical experiment, component analysis and mechanical experiment, 64 samples with different depths of 8 boreholes in the preselected area were analyzed,. The results show that the surrounding rock in the pre concentration area is mainly argillaceous and dolomite, and the internal structure of the rock is compact, with an average tensile strength of 10MPa. Compared with Opalinus clay rock in Switzerland and callovo Oxfordian mudstone in France, its tensile strength is excellent. It can be seen that yingejing depression in Bayingobi basin is feasible in engineering mechanics as a pre selection area for disposal of high-level radioactive waste claystone. |
