| description | The invention provides a roadbed filling method based on permafrost field stability, which comprises the following steps of: in a first construction stage, carrying out detecting to obtain a natural frozen soil upper limit position of foundation soil in a permafrost field, and filling a first layer of roadbed filler with a preset thickness; after standing for at least one freezing and thawing cycle, in a second construction stage, carrying out detecting to obtain an artificial frozen soil upper limit position of the foundation soil in the permafrost field; and if the upper limit position of the artificial frozen soil is higher than the upper limit position of the natural frozen soil, representing that the state of the permafrost field is stable, and carrying out next-layer roadbed filling construction. Filling construction of the next layer of roadbed is carried out under the condition that the stability of a permafrost field on the lower portion of the roadbed is guaranteed, and possible diseases caused when |
