千枚岩地层超深基坑支护监测与有限元分析
Support Monitoring and Finite Element Analysis of Ultra-Deep Foundation Pit in Phyllite Stratum
摘要: 本文以某千枚岩地层破碎站硐室超深基坑支护工程为实践载体，对施工开挖过程中主要的工况做了分析，在得到现场实测数据之后，采用数值模拟的方法对支护结构的变形特性及机理进行有限元分析，用得到的结果同现场监测数据比较研究，并重点研究钢支撑预应力变化对整体稳定性的影响。
Abstract: Taking the support engineering of an ultra-deep foundation pit in the chamber of a crushing station in phyllite stratum as a practical carrier, this paper analyzes the main working conditions during construction and excavation. Based on the field measured data, the finite element method is adopted to conduct numerical simulation on the deformation characteristics and mechanism of the support structure. The obtained results are compared with the field monitoring data, and the constraint mechanism of the prestress variation of steel supports on the overall stability is emphatically studied.
