The fabricated structure is a kind of structural style,part or all cast-in-situ concrete components of which are replaced by the precast ones,and then transported to the construction site to assemble directly.The fabricated structure is convenient and quick for construction,harmless to environment and of high quality.Based on the analysis of the current application of the fabricated structure in the industry of water transport and water conservancy in China,and carrying out scheme comparison,we put forward a new fabricated pile foundation retaining wall structure in inland waterway revetment projects.It combines the L revetment with the precast square piles together by the reserved rigid connection,and we study its work mechanism and construction process.Combining with an engineering case,we use the vertical-elastic-foundation-beam method to create the three-dimensional model and determine the structure scheme.The conclusion is drawn that “the light component has advantages in fabricated structure”,which provides a train of thought and method for the design of the fabricated revetment.
