摘要
沉降观测数据受各种因素影响,观测数据的处理极其重要,本文提出利用SPSS软件对建筑物沉降观测数据进行异常值探测并进行科学取舍的思路和方法,并经过样本测试,分析比较对实测数据的回归分析法中几种曲线拟合法在预测沉降点变化中的各自的有效性和精确性。
Settlement observation data affected by various factors ,treatment is extremely important observation data , we propose the use of SPSS software for building settlement observation data to detect abnormal values and trade -offs of scientific ideas and methods ,and after sample tests ,analysis and comparison of the measured data several regression anal-ysis predicting subsidence curve fitting point in changing their validity and accuracy .
