深基坑支护结构安全预警系统研究

Study of Security Early Warning System of Deep Pit Supporting Structure

深基坑支护系统的位移与变形不仅关系到基坑本身的安全问题 ,也影响到周边环境的安全 .构建了支护结构安全预警系统 ,并在分析研究深基坑工程设计和施工实测资料的基础之上 ,采用改进的BP神经网络 ,建立起支护结构位移预测模型 ,并就基坑支护安全监测预警指标进行了讨论 .

Displacement and deformation of deep pit supporting system concern not only security of the pit, but also the safety of the surrounding environment. A security early warning system of supporting structure is set up.Based on the analysis of project design and construction surveying materials, an improved BP neural network is applied to establish a forecasting model of the displacement of deep pit supporting structure, some discussions on the surveying and early warning targets about it are studied.
