An examination is performed on the use of soil-cement mixing walls that were treated previously as temporary structures left buried in the ground, as permanent piles to rationalize foundation structures and reduce environmental burdens. This study aims at utilizing the embedded portion of the soil–cement mixing wall as a permanent pile, and evaluates the bearing capacity and tensile resistance in the static axial reciprocal load tests. This paper firstly describes the background and the previous studies, and then summarizes the static axial reciprocal load tests for the single piles which is considered the construction method of soil-cement mixing wall. Subsequently, the evaluation method of bearing capacity and tensile resistance on the soil-cement mixing wall is discussed.
