Abstract：
Abstract Using the construction of a large deep-buried segmental immersed tunnel as an example, 6 feasible alternatives are proposed for the segment joint configuration based on various arrangements of the waterproof system and shear keys. Through comprehensive comparison in terms of design, construction, and maintenance, it is determined that the optimal segement joint option is "the double waterproof system with OMEGA waterstop at the internal side + injectable waterstop embedded at the middle / shear keys at the external side." However, an appropriate option should be selected based upon the practical conditions.
