摘要

本文根据基于振型叠加(modal summation)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,分别计算了大连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 seismic hazard analysis method based on modal summation technique was utilized to calculate the main vibrating parameters (mainly PGA, PGV and response spectra) for engineering sites by considering their surrounding historical earthquakes, geological structure and wave propagation characters. The estimated parameters with this method could be adopted as the basis for structural earthquake-resistance design.
