Motoring Technology On Deep Excavation Of Fengxichangan High-rise Building

After entering the 21 st century, the underground space got a great development. A mount of deep foundation engineering has been constructed and its dig depth and scale are still increasing. The monitoring technology is the guarantee of the safe construction of the deep foundation, and is the precondition of the construction informatization. The purpose of the foundation monitoring is to get clear of the supporting structure force and the excavation abounding soil deformation regulation. However, the monitoring scheme in many foundation excavation engineering is planed according to the subjective engineering experience. The arrangement of the monitoring location is always unreasonable and thus the detected regulation of the supporting structure is not correct. Such monitoring scheme has little meaning in directing the constriction of deep excavation.This paper takes the deep excavation of back moving building aside the Feng Xi Yuan station metro line 2(Fengxichangan High-rise building) as the background. In the first part, the research statues of monitoring technology of deep foundation are summarized. Followed is the background of the specific engineering project. And the monitoring scheme of this project and the monitoring data is analyzed. At last, by using the numerical simulation, the important location and item are surmised by analyzing the simulation results.
