摘要

基于大型振动台试验，研究小角度成层倾斜场地在倾向、走向、垂向、坡面方向、坡面垂直方向上的地震动响应特征，以及地层倾角对场地反应谱的影响规律。试验结果表明：在倾向方向，随着地层倾角的增大，倾斜场地的放大效应增大；在走向方向，当地层倾角小于12.5°时，放大效应强于水平成层场地；在倾向、走向方向，当地层倾角达到12.5°时，场地对反应谱短周期T≤0.1 s部分具有放大作用，对T＞0.1 s的部分具有削弱作用；在垂向方向，随着地层倾角的增加，倾斜场地的放大效应强于水平成层场地；在坡面方向，倾斜场地的放大效应弱于水平成层场地；在坡面垂向方向，倾斜场地的放大效应强于水平成层场地。该研究成果对小角度成层倾斜场地上的建筑物抗震设计具有一定的参考意义。

Abstract

With large scale shaking table tests

the effects of dip direction

strike

vertical direction

slope surface direction

dip angle and direction perpendicular to slope surface on seismic response of inclined and layered site are studied. The research results show that the amplification effect of inclined site in dip direction trends to increase with increasing dip angle of strata. In strike

the amplification effect of inclined site is stronger than that in horizontal layered site when the dip angle is less than 12.5°; in both dip and strike directions

when the dip angle reaches to 12.5°

the site has an amplification influence on the part of T ≤0.1 s period in response spectrum and a weakening influence on the part of T >0.1 s period. In the vertical direction

the amplification effect of inclined and layered site is stronger than that of the horizontal layered site with increasing dip angle. The amplification effect of inclined and layered site in slope surface direction is less than that of horizontal layered site

while the amplification effect in the direction perpendicular to slope surface is stronger than that of horizontal layered site. The research results provide a reference for construction design in inclined and layered sites with small dip angles.
