Abstract: In monitoring data analysis, data research is important for its reliability, and data processing effects analysis quality.This paper, combined with examples, discussed the importance of mutual corroboration of monitoring data from different monitoring items.Further, the utility value of non-stress gauge was pointed out, and the analysis method of partial least-squares regression was commended.At last, some issues need attention in time－effect factors selection were advanced.

摘要： 指出了大坝及工程监测资料分析时，监测资料的考证对资料分析可靠性的重要作用，论述了数据处理对资料分析品质的影响，阐述了资料分析时认真考察分析对象的必要性，通过实例说明了充分利用不同监测项目进行相互佐证对于提升监测分析可信度的意义，简要讨论了无应力计分析的实用价值，分析并推荐了偏最小二乘回归方法作为大坝监测资料分析的主要定量分析方法，同时指出了模型分析中构建时效因子时应注意的问题。
