On the background of the large diameter slurry shield crossing buildings at Baojian village in Weisanlu Yangtze River Tunnel（S line）

the authors establishe a three-dimensional numerical model to make a theoretical prediction on the main influence area and settlement value caused by shield crossing

and monitor the buildings within the area according to their classifications during construction process according to the predicted results.Then we combining with the field monitored data discuss the influence of shield construction on buildings

and putting forward corresponding control measures.Some conclusions could be drawn as follows:the main influence area and settlement value in shield construction can be predicted well in the three-dimensional numerical analysis

which can be used to guide the housing settlement monitoring and construction;improper controlling during shield construction makes uneven surface subsidence

buildings tilt and crack problems

and by controlling support pressure

adjusting construction parameters

such as the speed of construction and grouting

and grouting reinforcement for strata timely

ground settlement is effectively controlled.This ensures the progress of the construction smoothly.The results of this study can provide references in the large diameter slurry shield crossing buildings.
