海底隧道对我国来说是一个比较新的工程领域，对应的施工技术比较缺乏，特别是海域段安全快速通过断层破碎带的施工技术基本为空白，可借鉴的施工经验比较少。青岛胶州湾海底隧道建设者在吸取国内外先进技术的基础上依靠自主力量，突破了一个又一个技术难题，特别是在海域段过断层破碎带的施工难题上积极探索和实践，并已取得成功，积累了较为实用的综合施工经验，可为同类工程施工提供借鉴。

Undersea tunnel is a relative new thing in the engineering field in China. At present, Chinese builders lack construction technologies and construction experience in undersea tunnels, especially the safe and rapid construction technologies in tunneling through fault and fracture zones. For the construction of Qingdao Jiaozhou Bay undersea tunnel, the builders  atsorbed the advanced construction technologies both at home and abroad and depend on themselves. So far, they have conquered a series of technical problems, especially the construction difficulties in tunneling through undersea fault and fracture zones. The construction of Qingdao Jiaozhou Bay undersea tunnel not only accumulates many practical and comprehensive construction experience, but also can provide reference for similar projects in the future.
