揭示测量误差对概率积分法参数精度的影响程度问题.采用正交设计的方法对参数因子进行敏感性分析,得到下沉系数和拐点偏移距属敏感因子,主要影响角正切和开采影响传播角为不敏感因子;采用仿真计算的方法分析了测量误差对参数精度的影响.研究结果表明:以测量中误差与最大下沉值的比值作为衡量标准得到,当比值小于7%时求出的参数是可靠的,当比值大于10%时求出的参数是不可靠的.该研究结论放宽了沉陷监测对数据的精度要求,为矿山开采沉陷观测站的观测工作及仪器的选择提供依据.

@@@@To analyze the influence of measurement error on the parameters of probability integration, the orthogonal design was used to analyze the sensitivity of parameters factors. The results show that subsidence coefficient and the deviation of inflection point are sensitive factors and that the tangent of main effect angle and mining effect transference angle are no sensitive factors. In addition, the simulation method is used to analyze the influence of measurement error on the accuracy of parameters. Taking the ratio (m/W0) of measurement error (m) and maximum subsidence (W0) as a study criterion, the simulation results show that the parameters obtained are reliable when the ratio is less than 7%, and that the parameters are not reliable when the ratio is more than 10%. The conclusion in this study relaxes the required precision on subsidence monitoring data, and provides the basis for measuring mining subsidence in an observation station and selecting monitoring instruments.
