【摘要】 岩盐是一种特殊的岩体,由于其良好的物理力学特性,被视为是核废料地质处置的理想场所。由于核废料极强的放射性作用,使得在其地质埋藏衰变过程中,仍然放射出极强的能量,使得周围岩体温度升高。本文在实验研究的基础上,对在温度作用下,岩盐物理力学特性的变化进行了研究,并对该温度效应在地下处置库稳定性中的应用进行了一定的分析。结果表明,岩盐物理力学特性温度效应有利于维护处置库围岩的稳定,有利于核废料的安全处置。更多还原

【Abstract】 Due to its advantageous geological conditions and physical and mechanical characteristics, rocksalt is regarded as the host rock for nuclear wastes disposal. Study shows that nuclear wastes still have strongradiation energy, and make the surrounding rock heavily heated after many years of their underground disposal.So the study of the temperature effect on physical and mechanical characteristics of rock salt is important andessential to ensure the safety of nuclear wastes disposed in rock salt. Through a series of tests for heated rocksalt at different temperaturs ranging from 20□ to 240□ in this paper, a few positive conclusions are obtained.It is concluded that the temperature effect on physical and mechanical characteristics of rock salt is helpful tothe stabilization of nuclear waste repository and the safe isolation of waste from the outside biosphere.更多还原
