某预应力拱式梁桥的施工监控

对于某采用悬臂浇筑法施工的预应力拱式梁桥，为确保施工过程中桥梁结构的内力和变形始终处于容许的安全范围内，以及成桥状态符合设计要求，对其结构参数进行了监控。施工监控的主要内容有：线形监控、主梁断面应力监控、温度监控、混凝土弹性模量。

Construction Monitoring on Arch-Type Beam Bridge

In allusion to the prestressed arch-type beam bridge constructed with cantilever pouring method, its structural parameters are monitored in order to ensure that the internal force and deformation of bridge structure are controlled in allowable range and the finished bridge state accords with the design. The main subjects of construction monitoring are： line shape, section stress of main beam, temperature, elastic modulus of concrete.
