软土路基沉降与稳定监测异常数据的判别分析

Discrimination and Analysis on Abnormal Data in Settlement and Stability Monitoring for Soft Soil Subgrade

鉴于分析与判断软土路基沉降与稳定监测异常数据的重要性,对软土路基沉降与稳定监测异常数据的成因进行了分析,提出了综合应用监测指标、监控预报模型、监测关系曲线作为判断路基沉降与稳定监测异常数据的评判准则,并利用相邻监测点间存在的关联性及监测点的时序性判别异常监测数据,为软土路基沉降与稳定监测提供了有效的数据分析方法。

Considering the importance of analysis and determination of abnormal data in settlement and stability monitoring for soft soil subgrade, the abnormal causes are analyzed and the comprehensive applicable indexes, prediction model and relationship curve in monitoring are proposed to be the evaluation criterion for such abnormal data; and the relevance existing between adjacent monitoring points and the time sequence of the monitoring points are used to distinguish the abnormal monitoring data offering effective data analysis method of settlement and stability monitoring for soft soil subgrade.
