Abstract：Research purposes: The construction technology of the precast segment assembling bridge is in the development period in China． As such kind of bridge has its own features，the more attention should be paid to the durability，especially the durabilities of the segment joints and pretressing system． Combining with the practices of durability design and construction measure for the precast segment assembling bridge at home and abroad，this paper offers the key technical advices on the durability design of the precast segment assembling bridge for providing the reference to the similar works．
Research conclusions: In the durability design of the segment joint，it is important to set up the reasonable number and positions of segment joints and well make the structure design of the shear connector，and at the same time，the attention should be paid to the index requirement of the epoxy adhesive． If the bridge is of the prestressed structure，the full prestressing system should be adopted． The structure calculation and prestressing tendon adjustments should tally with the technical features of precast gegment assembling bridge． The grouting quality of pretressed pipe should be strictly controlled，and the attention should be paid to the shock absorption and anticorrosion of externally．
