文章通过对深埋核废料罐体在地壳运动作用下的受力以及破坏行为进行分析,为相关工程和研究提供参考。全文基于ABAQUS提出了膨润土,钢保护壳和核废料三维柱体水力耦合模型,通过模拟小断层倾角下核废料罐体受断层剪切作用破坏的过程,研究了不同断层面倾角,不同断层类型的断层错动对深层核废料埋置物的受力及破坏影响。通过对比分析0°、22.5°和45°三个不同断层面倾角以及正断层和逆断层两个不同断层类型作用下断层位移大小,膨润土受力状况,孔隙水压力的分布及变化,得出其膨润土受力破坏规律和孔隙压力变化规律,根据分析结果,提出核废料罐体埋置方案,为今后相关工程和研究提供有意义的借鉴。
The article analyzes the stress and failure behavior of the deep nuclear waste tank under crustal movement, and provides references for related engineering and research. Based on ABAQUS, a three-dimensional hydraulic coupling model of bentonite, steel protective shell and nuclear waste was proposed. By simulating the process of nuclear waste tank being damaged by fault shearing under small fault dip, the effects of different face dip and fault types Influence of fault dislocation on stress and failure of deep nuclear waste embedded. By comparing and analyzing the tilt angles of 0 °, 22.5 ° and 45 ° and the fault displacement, stress distribution and change of bentonite under two different fault types of normal fault and reverse fault, According to the analysis results, the paper puts forward the plan of nuclear waste tank embedding, which will provide meaningful reference for related engineering and research in the future.
