ABSTRACT
CONDUCTED: This paper introduces the deep foundation pit design calculation and field monitoring examples of Qifeng Park station of Dongguan rapid rail. Through the incremental method, this paper compares and analyses the monitoring results of the lateral displacement of underground continuous wall, reinforced concrete strut axial forces, surface subsidence and design calculating results, and concludes that the calculated value of foundation pit deformation is comparatively smaller than the measured value. The results show that the tau-effect of foundation pit has some influence on foundation pit deformation.
