The invention relates to the technical field of rectangular pipe jacking construction, and provides a rectangular pipe jacking construction settlement control method which comprises the steps that the geological condition of rectangular pipe jacking construction is analyzed and judged, and rectangular pipe jacking construction parameters are set according to the analysis and judgment result; monitoring positions are arranged on the rectangular pipe jacking construction line, and whether the construction line is settled or not during rectangular pipe jacking construction is monitored and judged through the monitoring positions; and for the subsidence area, grouting is conducted on the subsidence area through the grouting holes formed in the rectangular jacking pipe, and grouting compensation lifting is achieved. According to the method, it can be guaranteed that in the shallow-buried large-section rectangular pipe jacking construction process, the settlement conditions of all areas and all point positions of a
