深基坑安全监测与预警平台的开发与应用

Development and Application of Safety Monitoring and Early Warning Platform for Deep Foundation Pit

基坑开挖涉及大量不确定因素,其监测过程信息化受到越来越多的重视,兼容不同数据采集设备,选择恰当的预测模型与参数,提供方便、移动化的访问是信息化的难点。通过对监测流程的分析,提出了基坑监测平台体系结构,包括数据采集层、数据接口层、数据处理层、访问接口层、用户界面层。通过不同接口实现对不同通讯方式、协议的支持,并具可扩展性;针对不同监测项提供不同的预测模型库,通过强大的运算能力为每个监测点与监测项进行模型与参数的自适应选择与优化,提供最佳的模型与参数进行预测;平台采用J2EE架构开发,通过浏览器及APP提供图文丰富的监测与预测数据及报警信息。以该支护系统的某基坑监测应用,验证了平台的有效性及预测的准确性。

The excavation project involves a large number of uncertain factors. The informationization of monitoring process is paid more and more attention. Compatibility of different data acquisition equipment,choosing the appropriate prediction model and parameters,convenient and mobile access is the difficulty of informationization.The architecture of the pit monitoring platform is proposed through the analysis of the monitoring process,which includes data acquisition layer,data interface layer,data processing layer,access interface layer and user interface layer. The portal supports different communication methods and protocols support with different interfaces to achieve.Based on adaptive selection and optimization to models and parameters of individual monitoring point and individual monitoring item with different prediction model library according to monitoring item,the portal provides optimal model and parameters to predict. The portal is developed with J2EE platform,which provides rich graphic monitoring and forecasting data. Validity and accuracy of the portal are verified through a certain pit monitoring application with support system.
