The invention discloses a connecting traverse measurement distance error accurate distributing method. The connecting traverse measurement distance error accurate distributing method comprises the following steps: calculating a vertical coordinate increment correction number V Delta xi and a horizontal coordinate increment correction number V Delta yi of each traverse point according to a coefficient; distributing to obtain each corrected vertical coordinate increment Delta Xi= Delta xi+ V Delta xi, and horizontal coordinate increment Delta Xi= Delta yi+ V Delta yi; then, solving the coordinates of each traverse point according to coordinates of a point B and each corrected vertical coordinate increment and horizontal coordinate increment. The connecting traverse measurement distance error accurate distributing method takes traverse error offset and azimuth angles into consideration comprehensively; the distributing precision is higher than that of a conventional simple error distributing method.
