岩土工程安全监测异常值属性的识别方法

针对施工期间岩土工程安全监测系统具有不完善、干扰和影响因素多、人工监测比重大等特点，介绍了监测数据可靠性检查和异常值监测方法，在将异常值分为假异常、表观异常和征兆异常后，结合工程实践阐述了异常值属性的识别原则和方法，并以实例分析了常见的导致假异常和表观异常的原因。这些分析方法是监测数据处理系统的必要组成部分。

IDENTIFICATION METHOD OF SINGULAR DATA AND THEIR ATTRIBUTE FOR SAFETY MONITORING

The monitoring system of geotechnical engineering projects for the construction period is not perfect. Many affecting factors are involved and few automatic observations are applied. Methods of reliability examination and singular data identification are introduced. The singular data are divided into false singular data, formal singular data and predictive singular data; then the principle and method of identification of the attribute of singular data are expounded in combination with engineering practice. At the same time, the general causes of false singularity and formal singularity are analyzed. These methods are a necessary part of the observed data processing system.
