摘　　要：大连湾海底隧道沉管建设工程最终接头采用一种全新的最终接头型式——顶进节段法。考虑到顶进节段法最终接头在国内尚属首次,开展了小尺寸模型顶推工艺试验研究,对其顶进、回拉、监测和控制等顶推工艺进行了分析和验证,并提出相应优化建议与措施。The immersed section of the Dalian Bay Tunnel adopts a new type of closure joint constructed by the segment-jacking method.Considering that this kind of closure joint is the first in China,the jacking process test of a small-scale model was carried out to analyze and verify the process of jacking,pulling back,monitoring and controlling,etc.The corresponding optimization suggestions and measures are put forward.
