Abstract: Aiming at the practical problems existing in the application of a slope monitoring system and data analysis in engineering monitoring, a set of visual analysis system covering the entire process of data collection, processing, display, and analysis is developed and verified based on the Vue3 framework and Element Plus open source component library. This system realizes the automatic conversion of displacement directions and unifies the requirements of on-site monitoring system and data analysis. It achieves smooth processing of monitoring data by adopting the average method of monitoring values within a specific time interval, thus solving the problem of frequent data fluctuations caused by insufficient accuracy of monitoring equipments. It addresses the low stability issue of internal displacement data by means of stable date selection and realizes three-dimensional visual display of monitoring data through spatio-temporal alignment. Furthermore, it establishes standards for association analysis and fusion analysis of slope monitoring data that applicable to this system, enabling effective discrimination of slope deformation types, development stages, and inducing factors.The system can be used in conjunction with existing geological disaster risk monitoring platforms, featuring rich data sources, strong operability of data visualization analysis, and a high degree of automation. It can provide references for the in-depth analysis of slope monitoring data in similar engineering projects.
