摘要： PROBLEM TO BE SOLVED: To provide a soil-cement improvement body with the strength of an earth retaining wall with simple constitution. SOLUTION: This soil-cement column earth-retaining wall 10 has an earth retaining wall 12 partitioning the natural ground side 16 from the excavated face side 18. The earth retaining wall 12 formed in wall shape with the soil-cement improvement bodies 32, has a height that covers the height difference between the ground surface 17 of the natural ground side 16 and the ground surface 19 of the excavated face side 18, and resists soil pressure P received from the natural ground side 16. A plurality of collapse preventing walls 14 are joined to the natural ground side 16 of the earth retaining wall 12. The collapse preventing walls 14 are provided in a direction orthogonal to the earth retaining wall 12, and the collapse preventing walls 14 support the earth retaining wall 12 from the natural ground side 16 to prevent the earth retaining wall 12 from collapsing to the excavated surface side 18. The resisting strength of the earth retaining wall 12 to the soil pressure P can be adjusted by changing the number of rows of the soil-cement improvement bodies 32 extended to the natural ground side 16 and a space D between the adjacent collapse preventing walls 14.

摘要： PROBLEM TO BE SOLVED: To improve the joint strength of a joint part between a foundation part and a soil-cement improvement body. SOLUTION: The soil-cement improvement body 12 is continuously constructed in the ground 36. The soil-cement improvement body 12 is a wall body of a cylindrical column body and formed with recesses and projections 12S of circular arc shape at both side faces of the wall body. The foundation part 14 of a structure is constructed around a head 12H of the soil-cement improvement body 12, and a foundation beam 22 of the foundation part 14 is supported by a top part S1. The foundation part 14 is constituted to construct a foundation slab 23 on the ground 36 and to provide a floor slab 21 through the foundation beam 22. The periphery of the head 12H is excavated in a width dimension W and a depth dimension H, and the soil-cement improvement body 12 and the foundation slab 23 are joined with concrete 27.
