筒型基础系缆平台沉/拔过程侧摩阻力原型测试

Full Scale Tests of Skin Friction Forces During Penetration downPull up Processes of a Bucketfoundation Dolphin Platform

介绍了1999年首次安装在渤海锦州9 3地区多筒基础平台安装施工过程中的侧摩阻力原型测试研究,描述了筒型基础下沉和上拔过程中筒壁侧摩阻力的测试系统和测试方法,给出了主要测试结果并与现行规范进行了对比分析.这项成果对筒型基础平台的设计和施工具有直接的参考意义.

Two mooring dolphin platforms with bucket foundations were installed in JZ9 3 field of the Bohai Sea in 1999. Several items of the field measurements were performed during the installation. This was the first time in the country to carry out a series of full scale tests in the bucket foundation platform installation. This paper introduces briefly the measuring methods, instrumentation system and the main results of the lateral soil friction forces measurement during the penetration down/pulling up processes of the buckets. According to the results, discussions are given, and suggestions for the bucket foundation platform design are presented.
