The invention discloses a lining circular ring assembled by prefabricated segments with corbel connecting bases and an assembling method of the lining circular ring. The lining circular ring is provided with symmetrical double-sided wedge-shaped rings. The capping block assembling point is located at the 0-degree position of the lining circular ring, the ring width of the outer diameter of the circular ring at the point is the minimum value or the maximum value, the point, opposite to the capping block, of the 180-degree point is a first standard block, and the points, adjacent to the two sides of the first standard block, of the capping block are second standard blocks. The inner arc surface of the second standard block and the inner arc surface of the adjacent block are each provided with a corbel connecting base which is integrally formed and protrudes out of the inner arc surfaces, each corbel connecting base is composed of a connecting base face in the horizontal plane direction and a connecting base face in the vertical plane direction, the four corbel connecting bases are symmetrically distributed in the lining circular ring, and the formed lining circular ring is in a mode1 or a mode 4. The top sealing block and the adjacent blocks on the two sides are spliced into a whole to rotate by 180 degrees around the Y axis to be in place, and the first standard block and the standard blocks sequentially spliced with the first standard block are spliced into a whole to rotate by 180 degrees around the Z axis to be in place in a mirroring mode to form a lining circular ringin a mode 2 or a mode 3. The universality of the segment is improved, and drilling and steel bar planting on the inner arc surface of the segment are avoided.
