LAND FORMATION METHOD FOR FIELD SLOPE

摘要

PROBLEM TO BE SOLVED: To overcome problems such that there are no conventional standards for guaranteeing execution quality in the land formation of a small-scale field slope and such that the land formation thereof cannot be performed on the basis of the execution quality and execution costs desired by an execution user. SOLUTION: The back fill 2 off the small-scale field 1 having a fill height of 8 m or less and a slope gradient of 1 to 1.0 or below is reinforced by reinforcing fill 4 whereon a span bond is laid. In this case, various field slope formation design charts varying in the execution quality according to the way to lay the span bond are prepared in advance, and the field slope formation design chart selected from among them is used to create the field slope. The threshold value of the deformation of the field slope is specified for each execution quality, and each design chart guarantees a land formation method for the field slope, wherein the response value of the deformation of the field slope does not exceed the threshold value for each execution quality.
