Aiming at the design issues of lifting lug for large pre-fabricated caisson hoisting construction,we verify the strength of lifting lug and local concrete combining with oversea marine project,and propose the technical specifications for hoisting.Based on the European and American codes,we verify the strength of local concrete including compression strength,breakout strength,pullout strength,side-face blowout strength and pry out strength.The results show that the strength of lifting lug and local concrete satisfy the requirements.The strength of local concrete is the key problem in the design of the caisson wall as a thin-walled structure.In the process of hoisting construction,necessary measures should be taken to ensure that the lifting lug bears reasonable force.
