摘要

深基坑工程在城市建设中应用广泛，其支护结构的安全性直接关系到周边环境及施工安全。针对深基坑支护结构在开挖过程中的变形特点，结合监测数据分析与预警技术，对可能出现的失稳风险进行动态评估。通过实时采集支护结构位移、地表沉降及地下水位等多维度数据，构建高精度变形监测体系，并引入基于大数据和多参数耦合的预警模型，实现对异常工况的快速识别与风险分级响应。研究结果表明，科学合理的监测与预警技术可显著降低工程事故发生率，提升深基坑施工的安全可控性。

Abstract

Deep foundation pit engineering is widely used in urban construction, and the safety of its supporting structure is directly related to the surrounding environment and construction safety. According to the deformation characteristics of deep foundation pit supporting structure in the process of excavation, combined with monitoring data analysis and early warning technology, the possible instability risk is dynamically evaluated. Through real-time collection of multi-dimensional data such as support structure displacement, surface settlement and groundwater level, a high-precision deformation monitoring system is constructed, and an early warning model based on big data and multi parameter coupling is introduced to realize rapid identification of abnormal conditions and risk grading response. The results show that scientific and reasonable monitoring and early warning technology can significantly reduce the incidence of engineering accidents and improve the safety and controllability of deep foundation pit construction.
