重大工程设定地震方法研究进展
|
摘要
重大工程由于自身的重要性及其破坏的严重性,其设计地震动参数的确定不能再局限于经验统计,而应由专门的地震危险性分析来确定。重点分析地震动参数和衰减关系的选取、最大贡献潜源和震级、震中距的确定、不确定性分析等方面对设定地震的影响,指出了需要进一步研究的问题,并就地震动参数的合理选取、最大贡献潜源的确定等方面提出了几点建议。
The background and characteristic of the method of scenario earthquake for critical engineering project is introduced. A summary of status of researches in the scenario earthquake including the methods of weighted average and maximum probability is presented. The analysis for selecting seismic parameter and attenuation law, determining on the dominate potential earthquake sources and the magnitude and epicentral distance, uncertainty was made. Some problems which need further investigation and advice are suggested.
