Engineering Design Earthquake Ground Motion Parameters Of The Analysis

Seismic hazard analysis for engineering site means carry on scientific evaluation to earthquake influence degree that the site may be suffered eventually under the different time limit in the future. Base on the detailed study and analysis on the seismic activity, seismic geology background, and seismic source, propagation path, state of the site, study the seismic occurrence and the development regulations from the angle of the engineering and dissemination regulations of earthquake, attenuation regulations and earthquake influence to site. Its purpose is to provide basis for the engineering structure's anti- earthquake design, therefore, this research has very important meaning on carry out the target of quakeproof to reduce the disaster and services in the economic construction. Seismic hazard analysis for engineering site is one of the contents of the working for seismic safety evaluation.This paper studys the technique thinking way of seismic hazard analysis for engineering site in detail, and detailed study the seismic activity analysis, seismic geologies investigate, attenuation relationship of seismic, seismic risk analysis with probability in area and anear area according to thinking way, get design parameters of ground motion combinationing the site seismic condition and through the analysis for soil level seismic reaction eventually, and they can be provided to the design section for reference.According to engineering practice demand and its theories research conditions currently, this text includes the following contents:...
