摘要:
地裂缝对建筑结构的破坏是巨大的.随着西安地裂缝活动已趋于稳定和城市发展的需要,对地裂缝场地的利用提出了新的要求.针对地裂缝场地地震效应研究的不足,采用有限元法对西安某地裂缝场地进行模拟分析,研究了地震作用下输入地震动的强度、峰值位移及峰值加速度等因素对地裂缝场地地表峰值加速度的影响,定量地分析了地裂缝场地放大效应及上下盘作用效应,找出了地裂缝场地的动力响应规律,为地裂缝场地工程结构的抗震设防提供了依据.
Abstract:
A construction can be greatly damaged by the ground fissure. As the ground fissure in Xi’an has been stabilized and the need of country development, new requirements on the use of ground fissure sites have been put forward. As the lack of researches on the seismic effect, finite element method was used in the paper to simulate and analy ze a ground fissure site in Xi ’an. The peak acceleration affected by different direction of peak intensity, peak displacement and acceleration of seismic wave were analyzed. The “amplification-effect” and “hanging wall and footwall effect” were quantitatively analyzed and the seismic response of the ground fissure sites were found. A basis on the re search of earthquake resistance of engineering structures on the ground-fissure site was provided.
