Abstract:

Using the numerical simulation, we calculated and analyzed the process of excavation by section and block of foundation pit at Panjin underground commercial street. The results show that with the increase of the excavation section length, the maximum lateral displacement of supporting piles shows the tendency of reduction at first and increase afterwards; while the basement uplift shows the tendency of inereasing. With the increase of the excavation block length, the lateral displacement of supporting piles on protected sides shows the same tendency of reducing at first and increasing afterwards. Taking into account the spatial effect in the excavation, the long foundation pits can mitigate the deformation of supporting structure and formation effectively. Considering whether the excavated soil has enough strength to limit the deformation of supporting structure and formation in the process of foundation pit excavation with different section and block could make spatial effect significantly.

Key words: foundation pit excavation, spatial effects, numerical simulation, section construction
