摘要
深地层地下处置是目前首选的核废料处置方案。由于放射性核素的长期的衰变和辐射导致的某些不可预见性因素,综合评估和预测核废料处置场的安全性是至关重要的。本文从理论上分析了核废料地下处置过程中温度场、应力场、渗流场三场相互影响、相互作用的力学机理,并提出了核废料泄漏的防治措施,为核废料地下处置过程中环境评价提供了基础理论依据。
It is still the best way to disposal the nuclear waste in deep earth. The security of the waste repository should be predicted and appraised by both theoretical analysis and the results of the nature analogue study. The paper has analyzed the mechanics mechanism and the ineractions of the temperature field seepage field stress field in the course of nuclear waste material underground, and has put forward the prevention and cure measure that the nuclear waste let out, handled the environment in the course and appraised and offered the basic theoretical foundation for nuclear waste underground.
