城市地区深基坑信息化施工监测系统初探

Study on Informative Excavation Monitoring System of Urban Deep Foundation Pit

目前,城市地区深、大基坑的施工项目越来越多,对基坑施工实现信息化的要求也越来越迫切。深基坑工程的信息化施工,不但能检验基坑设计理论和方法的正确性,而且可为其发展创造有利条件。本文结合城市地区某地铁深基坑的监测,运用设计软件对基坑变形的实测数据进行了分析与反分析预测计算,提出了该方法的可行性及其不足;初步探讨了城市地区深基坑监测系统的结构组成及工况信息交流平台的构建理念,以期对深基坑信息化施工参考借鉴.

At present, in cities there are more and more large and deep foundation pit excavation＇s projects, which are urgent to realize informative excavation. The informative excavation of deep foundation pits not only could verify the correctness of foundation pits＇design theory, but also creates some favorable conditions for their development. Based on the monitoring of a subway construction shaft in one city, the foundation pit deformation of practice measured data is analyzed and back analyzed by some design software, and the feasibility and some disadvantages of the method are obtained. Then, the structure of monitoring system of urban deep foundation pit and the construction idea of information exchange platform of construction conditions are preliminarily discussed. In the end, we hope it will be available for reference to informative excavation of other deep foundation pits.
