The conventional space calculation method for the bracing system of the foundation pit,which is often used in engineering designs,is modified and an improved space calculation method is presented in the paper,which can realize the coordination of the plane frame system and the vertical pile bracings with displacement at the joints.An improved elastic resistance method is also proposed in the paper to calculate the vertical pile bracings.The calculation method as given in the paper can produce an ideal calculated result with a simple software but high speed of calculation,using less parameters,and more experience in selecting parameters,thus is worth being promoted in engineering practice.
