Abstract:

The composite retaining structure of soil-cement pile and concrete pile (named MC pile) is applied to the projects in recent years. Due to lack of researches in view of service mechanisms and deformation characteristics of the composite retaining structure, experience design method that lacks of theoretical basis is usually applied to design composite retaining structure in practical project. Through studying some problems of composite retaining structure, especially several key issues about designing MC pile retaining structure, the methods to design M pile and C pile are put forward; with the characteristics of the MC pile composite retaining structure, a new stability calculation method for the composite structure design is proposed. Finally, applying the design method to actual project, the results demonstrate the feasibility of the method.

Key words: MC pile, deep excavation engineering, composite retaining structure, design methodology, stability analysis
