摘　　要：结合工程建设实例,介绍大口径长距离土压平衡顶管掘进技术在港口施工中的应用。重点介绍在埋深大、顶进长及复杂软土地基的情况下,土压平衡式顶管掘进技术施工过程中需采取的施工方案和控制措施;分析与评价土压平衡顶管掘进技术的机理和实践应用,可为软土地基的设计和施工提供参考。Combining with the actual example of the project construction,the long-distance large-diameter pipe jacking EPB tunneling technology applied in the port construction was introduced. The construction proposal and control measures taken necessarily for deeply buried and long distance jacked pipe as well as the complicated soft ground when applying such technology are emphatically introduced. The earth pressure balance pipe jacking mechanism tunneling technology and the practice of application are also analyzed and evaluated. Which can be referred by the similar project.
