摘要:
地裂缝对工程结构的安全性影响巨大．在高烈地裂缝地区，若采用空间避让原则，势必浪费有限的土地资源，制约城市建设与发展．借助ABAQUS有限元软件建立了地裂缝场地和上部结构共同作用模型，并在土体底部输入不同的地震波，实现了跨地裂缝结构多点加载的模拟．通过比较不同工况下的弹塑性层间位移、层间剪力变化情况，较为清晰地揭示出跨越地裂缝的建筑物在地震作用下的工作特性，探讨了在不同的工况下跨地裂缝结构动力反应的变化规律，找出了结构跨越地裂缝最不利位置，为更深入研究地裂缝和地震共同作用对上部结构的损伤机理和灾害防治措施提供参考．

 

 
Abstract:
Ground fissures have a huge impact on the safety of engineering structures. If principle of space avoidance is carried out in Ground fissures site with high intensity, it will waste limited land resources and make urban planning and construction restricted. The modes of ground fissures site soil and the superstructure have been established by the finite element software ABAQUS in this paper. The simulation of multi-point loading of the structure crossing the ground fissure is realized by inputting different seismic waves at the bottom of the soil. Different locations about superstructure crossing the ground fissure have been set up which is based on different conditions. Elastic-plastic time-history analysis on the superstructure which is in the earthquake could be made while different seismic waves would be input from bottom of the soil. The elastic and elastic-plastic inter story drifts, the acceleration of the top, floor shear, and internal forces from the superstructure in different cases would be figured out. The performance of superstructure crossing the ground fissure under the uneven settlement and the earthquake would be shown clearly. The variation of dynamic response of the structure crossing the ground fissure under different working conditions is discussed. Then, the most unfavorable position about superstructure crossing the ground fissure would be found. Finally, in-depth study on damage mechanism from superstructure crossing the ground fissure under the earthquake and the ground fissure would be researched, and a reference to measures on disaster prevention would be provided.
