Numerical Analysis of the Construction Influence of Deep Foundation Pit on Adjacent Open Trench Tunnel

Abstract:

The open trench D ramp of Yingpanlu Xiangjiang tunnel in Changsha and the adjacent building foundation pit construction were excavated almost at the same time. The minimum distance between the two pits was only 8 meters, and keeping both projects safe working became difficult in engineering. Therefore a special project example of numerical analysis model was established, which can simulate the whole construction course. The construction stress was analyze by combining with the soil and retaining structures displacement, and the results were compared with the actual measured data to provide a reference to the design and construction optimization.
