本文通过对常用的钢弦式钢筋计、钢弦式砼应变计和差动式砼应变计的砼模型试验,着重对介质与传感器的变形协调问题和元件的率定及测试数据的转换处理方法进行了分析和研究。结果表明:对于测试元件必须具有稳定的工作性能和合理的结构尺寸,对于复杂受力状态下的应力型传感器,应通过“贴片率定法”将其转变为应变型后使用,并采用广义虎克定律进行数据转换处理,而“常用率定法”仅适用于简单受力状态下的数据处理。 In this paper, we use the 砼 model test of commonly used steel string steel gauges, steel string 砼 strain gauges, and differential 砼 strain gauges, focusing on the problem of media and sensor deformation coordination and component calibration and conversion of test data. Analyzed and studied. The results show that: for the test element must have a stable working performance and a reasonable size of the structure, for stress-type sensors under complex stress conditions, it should be used to transform into a strain type through the “patch rate method” and use the generalized tiger The law of law is used for data conversion processing, and the “common-use rate determination method” is only applicable to data processing under simple stress conditions.
