Abstract:

A composite stiffness matrix was proposed to describe the flexural performance of the soil cement wall and concrete piles mixed retaining structure. Based on Euler beam theory, both vertical and horizontal displacement functions were established by introducing a new degree of freedom—friction distance between concrete piles and cemented soil, and the flat section assumption and pile shear displacement method were used. Considering the potential energy generated by the friction of cement wall—concrete pile and pile tension, a composite stiffness matrix was derived. The proposed matrix was verified by an example and the displacement was in good agreement with the field data.

Key words:excavation; compound wall; cement mixing piles; bored piles; pile wall friction
