塑料排水法加固深水软基技术在洋山工程中的应用

Successful Adoption of the Technique and Equipment of Plastic Drainage Plates Strengthening Underwater Soft Foundations in Yangshan Project

为了能够快速加固海洋软弱地基,采用塑料排水法加固深水软基技术与设备,研制深水插板作业船,配以施工技术和质量控制办法。并在洋山港桥连接段海堤工程中得到实践和检验。成功地解决了深水软基快速处理的难题。

To quickly strengthen underwater soft foundations in sea,plastic drainage plates and the relevant equipment are adopted,and a ship for inserting underwater plastic drainage plates,together with the corresponding construction technique and quality control,is studied.This method has been adopted and verified in the connecting embankment of Yangshangang Bridge,successfully solving the difficult problem of quickly strengthening underwater soft foundations.
