Abstract

The invention discloses an earthquake risk analysis method for an underground structure of a subway station, and the method comprises the steps: deducing a structural earthquake demand risk probability analytic function and an earthquake damage risk probability analytic function which comprehensively consider essential uncertainty and cognitive uncertainty from the perspective of uncertainty transmission; according to the method, the essential uncertainty of seismic oscillation, structural material size and the like can be considered, the cognitive uncertainty of seismic risk, numerical approximation, model simplification and the like is comprehensively considered, and the limitation of singly considering the cognitive uncertainty of the seismic vulnerability function in traditional analysis is avoided, so that a more accurate seismic risk assessment result can be obtained.

Description

technical field [0001] The invention relates to the field of earthquake risk analysis, in particular to an earthquake risk analysis method for underground structures of subway stations. Background technique [0002] At present, in the process of solving the seismic risk probability analysis function, only the essential uncertainty caused by the inherent randomness of uncertain factors, such as structural material strength, size, earthquake motion, etc., and the uncertainty caused by incomplete knowledge are considered. Detrimental cognitive uncertainty. At the same time, the commonly used seismic hazard analysis mostly uses the mean curve or quantile value curve based on the logic tree method to quantify its cognitive uncertainty, and it is also unable to obtain the cognitive uncertainty caused by seismic hazard, numerical approximation, and model simplification. Uncertain earthquake risk probability. Contents of the invention [0003] The invention provides an earthquak...
