低频振动下某尾矿库坝体氡析出稳定性与坝体损伤标定方法

铀尾矿库坝体在低频振动下会产生裂隙或孔隙导致放射性气体氡逸出,危害人们生命健康及环境。为探讨在振动条件下尾矿库坝体氡析出稳定性与坝体损伤,通过制作尾矿库坝体模型,使用激振台实验模拟,在低频振动条件下收集氡析出数据,得到振动频率与尾矿库坝体损伤后氡析出之间的关系、坝体损伤等级与氡析出率、表面位移等物理数据的关系表。

Cracks or pores will be produced in the dam body of uranium tailings reservoir under low frequency vibration,which will lead to the escape of radioactive gas radon,which will endanger people's life,health and environmental safety.In order to explore the radon exhalation stability and dam damage of tailings dam under the condition of vibration,radon exhalation data are collected under low frequency vibration condition by making tailing dam model and using vibration table experimental simulation.The relationship between vibration frequency and radon exhalation after dam damage,and the relationship between dam damage grade and radon exhalation rate and surface displacement are obtained.
