Force Performance Analysis And Construction Measures Of H-pile And U-pile Connected

A conventional steel sheet piles exists insufficient of the stiffness and the large deformation of excavation;The steel sheet pile verticality is difficult to control ets.HUC combination sheet pile is another new applications immediately after the conventional steel sheet pile, not only HUC inherits the advantages of steel sheet piles,but also borrow large stiffness of the characteristics to solve the conventional steel sheet piles present in insufficient stiffness, deformation of foundation pit volume,low degree of vertical piles and poor sealing effect.HUC has construction speed, lock tight, waterproof performance, reusable features, has a strong advantage in the deep excavation engineering structure and function, safety, environmental protection.The paper research as follows:Introduction the Calculation of HUC(H-pile and U-pile Connected) Combined steel sheet pile:From the combination of steel sheet pile retaining wall design basis, earth pressure behind the wall stress analysis, water pressure behind the wall stress analysis,combination sheet pile wall design Methods and safety factors to consider during the design and other aspects of attention to matters describes compositions shaped steel sheet piles design principles.H-pile and U-pile Connected steel sheet piles and ordinary steel sheet piles stiffness of the neutral axis position changes:Relying on the knowledge of mechanics of materials,From the moment of inertia of the material section and the parallel axis shift formulas,Study on the change of stiffness of HUC(H-pile and U-pile Connected) Combined steel sheet pile,The effect of friction between the locking finite element software research of HUC composite steel plate pile stiffness change,in contrast with the actual theories.Analysis of stiffness characteristics of HUC composite steel plate pile:Studied under different loads, the same lock friction coefficient; under the same load, different locking friction coefficient and combined steel sheet pile curvature effect on the stiffness of the, stiffness characteristics analysis.Influence of construction deviation of HUC composite steel sheet pile on stiffness:Based on the analysis of the deviation caused by the construction method of the combined steel sheet pile in the construction process, the influence of the stiffness is analyzed according to the different deviation angle, and the measures to control the construction deviation are put forward.
