摘要
结构应力监测是施工控制的主要内容之一。以某大桥的施工监测试验为例,对预应力混凝土连续梁桥悬臂施工阶段力学行为进行了测试分析,对应力监测截面的选择及测点布置、数据采集、监测数据处理方法等进行了阐述。对大跨度桥梁施工控制具有一定的参考价值。
The structural stress monitor is one of main control contents in bridge constructing control. Based on the test data of construction monitoring in a large span bridge, carrys on testing analysis for mechanical behavior of cantilever construction stage in prestress concrete continuous bridge,expounds the stress monitor section choice and the measuring point arrangement, the data acquistiion,the monitor data processing method and so on. It has certainly reference value for the construction control of the great span bridge.
