摘要
The Crossrail project currently under construction in Central London has been described as ＂The Big Digon Steroids＂, obviously referencing the Central Artery/Tunnel project in Boston completed in 2007. Toaddress the multiple demands for timely construction performance monitoring, Crossrail envisioned theunderground construction information management system （UCIMS） to monitor construction progressand structural health along the entire route, with a network of geotechnical instruments （i.e. slope inclinometers,extensometers, piezometers, etc.） and tunnel boring machine （TBM） position information.The UCIMS is a geospatially referenced relational database that was developed using an open sourcegeographic information system （GIS） that allowed all stakeholders near immediate feedback of constructionperformance. The purpose of this article is to provide a brief history of geotechnical andstructural monitoring software, to describe the structure and operation of the UCIMS, and to demonstratehow the functionality afforded by this system provided the requisite feedback to the stakeholders.Examples will be given regarding how the data management and visualization concepts incorporatedinto the UCIMS advanced the geotechnical construction industry. 2015 Institute of Rock and Soil Mechanics, Chinese Academy of Sciences.
