放射性廢棄物最終處置場址次要斷層帶或變形帶位移危害度分析技術研究

Seismic impact to radioactive waste disposal facilities may include strong ground-motion impact, fault displacement and ground deformation impact. Coseismic surface displacements associated with a major earthquake may cause significant damage to structures located on or near faults and may influence future structural maintenance unless proper structural design have mitigated this hazard. A method have been proposed by Youngs et al. (2003) to estimate fault displacement in a similarly probabilistic manner as the probabilistic seismic hazard analysis (PSHA). Probabilistic fault displacement hazard analysis (PFDHA), is one such procedure that provides an estimate of expected levels of slip on a fault due to surface rupture. Thus, the study tries to continue the two previous project: “the review of seismic hazard assessment for radioactive waste disposal facilities” and “Study on coseismic displacement measurement method for secondary fault zone or shear zone”, and proceeds with the analysis of assessment methods and practical application.
