| 中文摘要: |
| 根据绵阳市新城区地震地质构造环境和工程场地地质条件,建立了107个土层地震反应钻孔计算模型,采用工程场地地震安全性评价工作中通用的地震危险性分析方法和土层地震反应计算程序包(ESE)进行了多遇地震、设防地震、罕遇地震作用下的地震危险性分析和土层地震反应计算,给出了该城区各分区的抗震设计地震动参数值,此结果大于直接根据现行国标区划图得到的结果,因此选用此结果进行建筑结构抗震设计会更安全可靠。 |
| 英文摘要: |
| Based on the seismogeological structural environment and engineering site geological conditions of the new urban area of Mianyang City, 107 borehole calculation models for soil layer seismic response have been established. Using the seismic hazard analysis method commonly employed in seismic safety evaluations of engineering sites and the soil layer seismic response calculation program package (ESE), this paper has conducted seismic hazard analysis and soil layer seismic response calculations for frequent earthquakes, design earthquakes and rare earthquakes. The ground motion parameter values for seismic design of each subzone in this urban area are provided. The results show that these values are higher than those obtained directly from the current national standard zoning map. Therefore, using these results for the seismic design of building structures will be safer and more reliable. |
