摘要
建立了地道桥与地基空洞的静力、动力模型,并进行非线性有限元计算.考察地基空洞对框架式地道桥受力状况的影响,分析了由地基空洞引起的框架式地道桥裂缝的发生机理,为框架式地道桥的设计、施工和裂缝防治提供了参考和依据.
Through the static and dynamic calculation, on one hand, this paper analyzes the influence of the hole in foundation upon frame-type tunnel bridge, and clarifies the formation mechanism of the crack of frame-type tunnel bridge caused by the foundation's hole. On the other hand, this paper provides some useful reference for the frame-type tunnel bridge's design, construction and the prevention or repair of the crack.
