桥梁施工是一个复杂的系统工程,桥梁施工的过程也就是该系统的运行过程,施工过程中结构的受力状态、安全性能和成桥状态是桥梁施工控制的目标,在整个施工过程中,受许多确定和不确定因素的影响,会使实际状态与理想目标状态之间存在一定的差异。因此,对施工状态进行实时监测、预测、调整,从而实现设计目标就成为桥梁施工控制的中心任务。 Bridge construction is a complicated system engineering. The process of bridge construction is also the operation process of the system. The stress state, safety performance and state of bridge construction during the construction process are the targets of bridge construction control. During the whole construction process, Many determinations and uncertainties affect the actual state and the ideal state of the target there are some differences. Therefore, it is the central task of bridge construction control to monitor, predict and adjust the construction status in order to achieve the design goals.
