Methods of design and technological demands of construction are expounded for the structure with pre-stress tubular pile and anchor in the engineering of foundation pit. The design parameters for the pit are demonstrated by the means of FEM, and its feasibility is proved by the engineering practice. In the model of FEM, some pressure forces are imposed on the middle beam to simulate the anchor’s real mechanical properties. Taking into account the top ring beam and pre-stress tubular pile embedded each other very well, the straight beam element is adopted to simulate mechanical properties both of them. And the non-thickness interface element is also adopted to simulate the mechanical characteristics between the surrounding soil and the retaining structure, These experiences of design have important denotation for other similar foundation pit engineering.
