摘要:The horizontal displacement of pit top and horizontal displacement in deep soil of underground garage deep foundation pit in Radio and TV centre of Shandong province was analyzed. Combing the deformation control value of foundation pit, we thought that the supporting structure was safe and reliable. The supporting structure could not only meet the strength requirements but also meet the deformation control requirements. This deep foundation pit was a successful case under complex conditions. Analyzing the variation rules between monitoring data and construction time, the instructive conclusions were obtained. The deformation of foundation pit external corner was largest. The external corner should be avoided in foundation pit. The dynamic loads around foundation pit had a great influence on the safety and stability of pit. The rainfall was disadvantage factors, so the construction of foundation pit should keep away from the rainy season. The foundation pit floor could limit soil deformation and improve the safety of pit. The pit floor should be constructed as early as possible.
