大跨度连续刚构特大桥施工监控技术探讨

Discussion on Construction Monitoring Technology of Long Span Continuous Rigid Frame Super Large Bridge

大型预应力混凝土连续刚构桥在施工过程中会经历一个复杂的过程,由于桥梁结构的实际状况偏离了预期状态,因而会受到许多不确定因素影响。桥梁的形状和应力不能满足设计要求。因此,有必要监视桥梁的施工。即有必要对结构偏差进行分析和调整,以满足基于结构分析的设计偏差,并满足桥梁的对准和应力目标。

The large-scale prestressed concrete continuous rigid frame bridge will experience a complex process in the construction process.Because the actual situation of the bridge structure deviates from the expected state, it will be affected by many uncertain factors. The shape and stress of the bridge can not meet the design requirements. Therefore, it is necessary to monitor the construction of the bridge. In other words, it is necessary to analyze and adjust the structural deviation to meet the design deviation based on structural analysis, and to meet the alignment and stress objectives of the bridge.
