Abstract Research purposes: Determine the type of composite retaining structure and investigate the stress and deformation of the structure is the core when the structure is set up in the existing subgrade. Based on the practical engineering, field tests at different construction stages are carried out to study the combined force and deformation law to analyze the cooperative bearing mode of the structure.
Research conclusions: (1) The earth pressure on the back of the pile-sheet wall increases with the distance from the pile top, and the earth pressure adjacent to the cantilever retaining wall increases first and then decreases and finally increases. The earth pressure behind the pile decreases first and then increases. (2) With the increase of filling height, the bending moment of pile increases first and then decreases with the increase of distance from the top of new pile, and the pile displacement decreases with the distance from the new pile top. (3) The simplified force model of composite structure is proposed from the measured data. (4) The study can provide technical support for the application of the composite structure in the railway subgrade widening project.

Key words： the new pile-sheet wall the existing cantilever retaining wall deformation analysis cooperative bearing mode
