本标准为评估核设施厂址地面永久变形提供准则和指导。地面永久变形(PGD)是因构造面断层破裂和变形所导致的。本标准的目的在于为执行概率性断层位移风险分析(PFDHA)、地表破裂风险和概率性构造面变形风险(PTDHA)以及伴随隐伏断裂位移所导致的地表变形提
This standard provides guidelines and guidance for the assessment of permanent deformation of the ground of nuclear facilities. Permanent ground deformation (PGD) is caused by fault rupture and deformation of the structural plane. The purpose of this standard is to provide a basis for performing PFDHA, PTDHA, and surface deformation due to buried fracture displacements
