摘要:
根据高墩弯连续刚构桥从裸墩、悬臂浇筑施工到成桥各阶段的受力特点,将成桥后主梁对主墩的约束作用简化为等效约束刚度的弹簧,利用Hamilton原理,推导高墩自体、悬浇施工以及成桥阶段的动力稳定方程,进一步退化为静力稳定问题,得到了静力稳定系数表达式,并分析了诸因素对高墩弯连续刚构桥稳定性的影响。从而寻求高墩大跨弯连续刚构桥梁空间稳定性的实用简便算法。通过实例分析,验证其计算结果的可靠性。
Abstract:
According to the character under power of Curved Continuous Rigid Frame Bridge with High Pier from single pier, cantilever construction to completed bridge, the equivalent restraint stiffness spring is utilized to simplify the main beam constraint to the main pier in the state of completed bridge. The dynamic stability equations of structures in each stage are derived by Hamilton principle and are converted to the static stability equations. Based on them, the static stability factors of structures are obtained and the effect of various parameters to the stability of Curved Continuous Rigid Frame Bridge with High Pier is studied here. The purpose of the paper is to seek the applied and simple stability analysis arithmetic of Long Span Curved Continuous Rigid Frame Bridge with High Pier. Through the case study to verify the calculation results have a certain reliability
