Abstract

The invention relates to the field of engineering site earthquake effect evaluation, in particular to an engineering site earthquake hazard analysis method considering the effect of potential earthquake source orientations, which comprises the following steps: step 1, defining an engineering site earthquake affected zone; step 2, defining a potential earthquake source; step 3, establishing a site earthquake effect analysis framework; step 4, establishing an earthquake annual incidence rate matrix; step 5, establishing an earthquake effect intensity matrix; step 6, determining the exceeding rate of earthquake effect intensity in different orientations; step 7, calculating the exceeding probability of the earthquake effect intensity in the different orientations. The engineering site earthquake hazard analysis method has the benefits that the effect of the potential earthquake source orientations on an engineering site earthquake is fully considered, the deviation between an earthquake hazard analysis result and an actual earthquake effect is reduced, and the requirement of engineering anti-earthquake for the analysis of an earthquake damage way is met.

Description

technical field [0001] The invention relates to the field of engineering site earthquake impact evaluation, in particular to an engineering site earthquake risk analysis method considering the influence of potential source orientation. Background technique [0002] Seismic hazard assessment of engineering sites is an important part of engineering seismic work, and its main purpose is to provide design basis for engineering earthquake resistance. Many large and medium-sized cities in my country are located in earthquake zones, where there are large populations, dense buildings, and more and more dependence on lifeline projects such as water, electricity, and natural gas. In order to ensure the steady development of social economy and the safety of people's life and property, the seismic risk assessment of engineering sites for the purpose of anti-seismic fortification, disaster reduction and prevention is particularly important. [0003] Seismic hazard (Seismic Hazard) refer...
