PROBLEM TO BE SOLVED: To provide a soil improvement construction method for allowing a worker to evaluate the effect of restraining ground soil properly in advance, decide a shape and arrangement of rational improving body, and then construct the improving body with reduced cost. SOLUTION: In this soil improving construction method, such improving body 1 that restrains deformation of the ground when receiving load and being deformed is arranged and constructed in the ground. If stress of the soil to be improved in a case of filling construction is increased, the effect of restraining the soil deformation being different depending on the shape and arrangement of the improving body 1 is obtained as a variation of stress of the ground soil by a finite element method in advance. In addition, a variation of strength or rigidity of the ground soil to be caused by the variation of the stress is obtained based on the variation of the stress. After the shape and the arrangement of the improving body tending to increase this variation are decided, this improving body is constructed. COPYRIGHT: (C)2011,JPO&INPIT |
