PROBLEM TO BE SOLVED: To provide a support system for shallow layer ground improvement work and a shallow layer ground improvement method using the system, for enabling uniform mixing work, without relying on skills of experienced operators, by quantifying and making visible the mixing work between an improvement material and soil in a shallow layer ground improvement method, in addition to enabling tracing of the mixing work.SOLUTION: A support system for shallow layer ground improvement work includes: GPS positioning means that identifies a location and orientation of a backhoe; bucket movement recording means that divides a construction area into a plurality of segment groups based on a virtual three-dimentional coordinate system, identifies a bucket position based on the position and orientation of the backhoe, and records a number of times that the bucket passed through any of the segments contained in the segment groups; and a monitor displaying the number of passages through each segment.SELECTED DRAWI
