    • 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.
