Unbalanced foundation pit support design method
A unbalanced foundation pit support design method comprises the steps of determining parameters of a foundation pit design model; determining a displacement mode of a support structure; determining the position of an inner brace (3); determining the parameters of a support structure at one deeper side of a foundation pit according to a traditional single fulcrum pile static balance method; determining the parameters of a support structure at one shallower side of the foundation pit according to a soil pressure computation method opposite to the traditional mode; supporting at a bounding surface between the deep foundation pit and the shallow foundation pit by adopting a traditional cantilever support structure; determining a support structure material and reinforcing bars according to a maximal bending moment and a maximal shear force of each support structure; finally performing whole stability checking calculation, antidumping checking calculation, and anti-heaving stability checking calculation. By adopting the unbalanced foundation pit support design method, the characteristic of unbalanced pressures at two sides of the unbalanced foundation pit is fully used, the pressure resistant property of a soil body is played, materials are saved and construction period is shortened under the premise of ensuring safety, and the method has very high promotion and application values.
