高放废物处置地下实验室结构稳定性评价方法
Structural stability evaluation method of Underground Research Laboratory(URL)for geological disposal of high-level radioactive waste in China
摘要
Abstract
Underground Research Laboratories(URLs)play a crucial role in the siting process of high-level radioactive waste disposal.A study of evaluating the structural stability of Beishan URLs site was carried out,considering regional seismic and geological environment.After over a decade of site stability evaluations,techniques were developed to identify weakly active faults in stable crustal areas and assess their seismic potential.A method for determining design seismic motions was proposed,accounting for the source,propagation path,and local site characteristics.An efficient,high-precision time-domain analysis method for deeply buried,complex URL systems was proposed,along with a rock-structure numerical model to reveal seismic performance and its impact on the structural stability of the Beishan URL.The research determined the seismic fortification intensity for the Beishan URL,provided key seismic input parameters for structural design,and presented the seismic response results,supporting the construction of a site descriptive model(SDM)and site suitability assessment for the disposal repository.关键词
