本文利用噪声分离相对比较和动态基线带统计确定的方法,对双塘等五台七孔电感法相对地应力测量的悬空与受力元件观测值的部分统计参数进行了估算和对比,并从统计分析的角度指出:现有的悬空元件,在安置恰当且对其采用与受力元件相同的、有效的数据处理方法的前提下,其测值才有可能对受力元件测值的动态变化起检校作用。
In this paper, by using the relative comparison of noise separation and the method of statistic determination of dynamic baseline, some statistic parameters of the observation values of the suspension and force components of relative stress measurement of five seven-hole inductances such as Shuangtang were estimated and compared. From the point of view of analysis, it is pointed out that if the existing suspended elements are properly placed and the same effective data processing methods are used for the suspended elements, the measured values of the existing suspended elements will be likely to affect the dynamic changes of the measured values of the stressed elements Calibration effect.
