PROBLEM TO BE SOLVED: To provide a ground structure capable of limiting deformation of the ground at a time of an earthquake and to provide a ground improvement method to be executed for constructing the ground structure.SOLUTION: A ground structure includes: a liquefiable layer 10 which liquefies when seismic movement is applied thereto; and a ground improvement body 11, constructed on the liquefiable layer 10 with soil having fibers added and mixed therein, on which a pavement section 12 with a vehicle travelling thereon or a structure is constructed. A ground improvement method includes a process to construct the ground improvement body 11 on the liquefiable layer 10 by adding fibers to and mixing the same with the soil in a ground superficial section on the liquefiable layer 10. |
