人造地震动合成的研究现状及展望

State of the Art and Prospect of Artificial Ground Motion

结合随机过程的模拟方法,对国内外人造地震动的主要合成方法及研究现状进行述评.重点介绍以场地反应谱为目标的间接拟合方法,以及考虑震级、距离、场地及发震断层等综合影响的半经验综合方法的研究进展.最后,指出现有拟合人造地震动存在的主要问题及今后的主要研究方向.

Integrating with the simulation method of stochastic process, the authors present the review of the main synthesis methods and current research on artificial ground motion both domestic and abroad. The indirect synthesis method taking the site response spectrum as objective is mainly introduced, the development of semi-empirical comprehensive method considering seismic magnitude, distance, site and fault causing earthquake is also introduced. The main problems existed in current artificial ground motion synthesis and the research tendencies are pointed out.
