Development of database of monitoring results for retaining walls of deep excavations

Abstract
This paper presents several results obtained from the monitoring process of multiple deep excavations performed in Bucharest area. These projects comprised several retaining structures for deep excavations in Bucharest with 2 basement levels or more (more than 6 m in depth), using top – down method or supported by struts or ground anchors. The retaining walls for the deep excavation were monitored during the works for wall deformations (inclinometers), ground settlements, neighbouring building settlements, groundwater level variation etc. The database was started by the authors several years ago for Bucharest specific lithology and geotechnical characteristics, and through this paper supplementary data available is considered. Thus, the previously evaluated indices and ratios, such as the ratios between the excavation depth and length and thickness of the retaining wall, or the ratio between vertical displacement of the ground outside the excavation and horizontal displacement at the top of the retaining wall are reanalysed and updated values are provided. These data and the comparisons made between the projects are very useful to designers for future similar works.
