摘要

根据改进的基于振型叠加(mode superposition)技术的地震危险性确定性分析方法,结合区域地震活动性、地质构造和地震波传播特点,通过计算理论地震图途径,分别计算了城市周边各个地震对各个场点所造成的最大影响强度(主要以峰值加速度、速度和位移体现),所确定的参数可为结构抗震设计工作提供客观依据。
The improved method of seismic hazard analysis,based on mode superposition technique,is applied to calculate the main vibrating parameters(mainly PGA,PGV and response spectra) for any engineering site by considering its surrounding historical earthquakes,geological structure and wave propagation characters.The estimated parameters by this method can be adopted as a basis for earthquake-resistant design of structures.
