Abstract: Space distribution of foundation pit engineering for metro transfer station, which consists of vertically crossed station excavation, connected aisle and running tunnel, is complex. Numerical simulation method is usually used to analyze the construction impact of pit on adjacent buildings. Because of complicated structure and large excavation size, it is difficult to establish an integrated model to simulate construction process with single microcomputer; and numerical method does not work smoothly due to a large number of grids. In the numerical simulation of Qianshan Road metro station in Hefei, in order to overcome this problem, the complex metro foundation pit is divided into global model and one local model. The ultimate results of global model will be exported as a result of initial displacement field in local model; and then the local model is further excavated to study the influence of pit construction on neighboring buildings. Taking inverse distance weighted method and elementary interpolation method for examples, two kinds of initial displacement field of local model will be obtained by these two approaches. The calculating results of two methods are compared. It is shown that the results obtained by using displacement superposition method, which is consistent with the ones obtained by calculating separately, can used as the results of overall model approximately. The feasibility of displacement superposition method is verified. Comparing the inverse distance weighted with the elementary interpolation method, the former has a higher precision than the latter. The results play a guiding role in numerical simulation of complex foundation pit engineering.

Key words: metro station, complex foundation pit engineering, numerical simulation, displacement superposition
