Ultimate Bearing Capacity of Bottom Sealing Concrete in Underwater Deep Foundation Pit: Theoretical Calculation and Numerical Analysis

The cofferdam method is generally applied in the construction of underwater pier foundation bridge engineering, and pouring bottom sealing concrete one important links cofferdam. can prevent water seepage balance main body cofferdam, its structural size quality have a great influence on above functions. Under condition large level difference, it difficult to determine reasonable thickness concrete. There are few related studies this field, there lack systematic summary calculation theory. This work theoretically deduces approximate solution ultimate bending moment stress concrete, introduces two different methods, systematically summarizes methods three kinds stress, analyzes bonding force, uses ANSYS finite element software simulate specific model, compares with theoretical results. maximum obtained by closer actual monitoring data than traditional method, force be used make rough estimate.
