• With the wide application of foundation pit engineering, the design scheme of supporting structure needs to be adjusted accordingly. The optimization of retaining structure and deformation control of foundation pit are focused on as the important problems during the construction. The finite element model of a foundation pit in Suzhou was established; the simulated results are in good agreement with the measured ones. The maximum foundation heave of foundation pit is 3.63 cm, the maximum surface settlement is 3.12 cm, and the maximum displacement of pile is 2.18 cm. The sensitivity of the parameters of the retaining pile was discussed. The maximum displacement of the pile increases significantly with the decrease of the pile diameter. Pile spacing increases from 3 to 6 m, and the maximum bending moment of pile increases by 458.971 kN·m. The insertion ratio and elastic modulus have little effect on pile position movement. The surface subsidence changes little under the influence of various parameters.
