The utility model discloses a shield tunnel shears formula and spouts soon and freeze shutoff iterative structure, include: spout the wall soon, it is located intact section of jurisdiction and inclines, what spout the wall soon highly is not less than the section of jurisdiction internal diameter, freeze the wall, it also locates intact section of jurisdiction side, just freeze the wall with it freezes the wall to spout the wall coincide soon and form to spout soon in the section of jurisdiction, freeze highly being greater than of wall spout the height of wall soon, it is less than along thefore -and -aft thickness in tunnel to freeze the wall spout wall along the fore -and -aft thickness in tunnel soon, it is greater than along the circumferential width in tunnel to freeze the wall spout wall along the circumferential width in tunnel soon, and the freezing pipe who freezes in the wall is the double tube body structure. The utility model discloses the shear strength height, the moreconventional gravity wall
