摘要
阐述了灰色预测理论GM(1,1)模型和灰色关联度理论的基本原理.利用灰色预测解决可靠度计算中荷载和抗力统计资料的不足,为荷载和抗力分布类型和估计提供了科学的依据;利用相关度理论计算可靠指标与荷载之间的相关度,为工程的安全监测提供依据.
Grey mathematics is a burgeoning science which crosses applied science,social science,structural mechanics and other subjects.This thesis solves two questions by grey forecast and correlation degree theory in grey mathematics.Firstly,the absence of the stat.data of load and resisting force in structural reliability can be settled by the grey forecast and it provides scientific base for the estimate of the distributing type of load and resisting force;Secondly,the correlation degree between reliability index and load can be calculated by correlation degree theory,which provides scientific base for the safety inspection of project.
