摘　　要：以山区坡体上的建筑为研究对象,利用动力时程分析法,输入3条实测地震波和1条人工合成地震波,研究坡体建筑同水平地面建筑动力响应规律的区别和联系。计算结果表明,由于坡体土体对结构的延缓作用而使得坡体建筑动力响应没有水平地面建筑强烈,但由于坡体建筑中桩既抗滑又承重,内力比水平地面建筑要大。研究成果有助于边坡体建筑的抗震设计。Taking the buildings on the mountain slope as the research object and using the dynamic time history analysis method,the contracts and differences of the dynamic response laws between the slope buildings and level ground buildings by inputting three real seismic waves and a synthetic seismic wave.The results show that because of the delaying effect for the slope soil to act on the structure,the dynamic response on the slope buildings is less intensive than that on the level ground buildings.But as the pile in the slope buildings is not only anti-slide but also load-bearing,their internal force is stronger than that of the level ground buildings.This research result would be conducive to the seismic design of slope buildings.
