摘　　要：该文采用基于转变点理论的标准正态检验法,对贵州贞丰煤电厂垂直位移监测进行了粗差检验,结合实测数据进行计算、并与经典的粗差检验方法莱因达准则和t检验法进行对比分析,验证了该方法具有良好的粗差检验效果,可以对监测数据中的粗差进行快速准确的定位。In this paper,the standard normal homogeneity test(SNHT)based on the change-point theory is used to test the gross error of vertical displacement monitoring about Zhenfeng Coal-fired Power Plant,Guizhou Province.Combining with the measured data,the test results are compared and analysed with the classic gross error methods such as Pauta's Criterion and Student's t test.It verifies the method has good gross errors effect,it can locate the gross errors in monitoring data quickly and accurately.
