活动套管在平潭海峡大桥勘察中的应用

摘要

This paper introduces the investigation of Pingtan strait bridge over sea which is blowy and larger tidal. One advanced technology,which is retrievable casing, can overcome some difficulty in sea ar-ea drilling,such as shaked drilling ships,large-scale tidal range,and so on, it can improve work efficiency significantly,promote safety production,and provide powerful guarantee for finishing the engineering. This paper can also provide reference for other similar projects.%该文介绍了在风大浪急且有较大潮差的平潭海峡跨海大桥勘察中，应用活动套管这一先进工艺，成功克服了海域钻探船舶晃动严重、潮差大等困难，显著提高了工作效率，促进了安全生产，为顺利完成该项目提供了有力保障。该文也可为其它类似工程提供借鉴作用。
