Abstract

Abstract:

In a foundation pit group project, complex excavation stages and large number of monitor data can be encountered, so that the operators are hard to handle the analysis of the interactive impact of the excavation processes on the adjacent foundation pits. To resolve this problem, an analysis system was developed to monitor data and construct information in a foundation pit group synchronously and dynamically. The system used Microsoft SQL Server to facilitate the classification and management of the information of constructions and instrumentations, the time related fields were selected as the reference for the synchronous analysis. The visualized modeling for the excavation processes and the monitor data was conducted through the secondary development of Microsoft Visio and Excel, respectively. A console application was utilized to link and control these models. The system was applied in the synchronous and dynamic analysis of the construction processes and the monitor data in the project of Shanghai Expo foundation pit group, and exposed the interactive impact characteristics of the adjacent excavations in a global and local time/space domain. The system provided an efficient means for the analysis and verification of theories of the interactive impact in the excavation of foundation pit groups.
