| 摘 要： | 以华庄公路关山隧道为研究对象,通过建立大型三维有限元模型,采用一种人工构成的短时间正弦扫描Johnson/Epstein地震记录进行地震动力分析.该记录具有在较短时程内包含较大的实际地震频率范围的特点,从而减小计算分析的持续时间.通过对3种工况(不设置抗震缝、设置2条和3条抗震缝)计算,结果表明:关山隧道衬砌结构的动力... |

| Abstract: | Taken Guanshan tunnel of Huazhuang highway as the research subject,the seismic dynamic response characteristic was analyzed by using large-scale 3D finite element model and an artificial synthesized short-time sinusoid scan wave,Johnson/Epstein,which has the character of involving more extensive frequency of seismic wave so as to decreasing computing time.The calculation result of three working conditions(no aseismatic joint,two joints and three joints) demonstrates that(1) the principal mechanic characteri... |
