The PISA Joint Industry Research Project was concerned with the development of improved design methods for monopile foundations in offshore wind applications. PISA involved large-scale pile tests in overconsolidated glacial till at Cowden, north-east England, and in dense, normally consolidated marine sand at Dunkirk, northern France. This paper describes the experimental set-up for pile testing, with unique features of load-application mechanisms and built-in fibre optic strain gauges. New procedures are described for the interpretation of pile loading data, and specifically for providing precise interpretation of pile displacements.

仪器化中规模单桩现场测试的新数据分析方法

PISA联合工业研究项目关注海上风电应用中单桩基础的改进设计方法的开发。PISA在英格兰东北部的考登（Cowden）进行了超固结的冰层，在法国北部的敦刻尔克（Dunkirk）进行了密集，通常固结的海沙中的大规模桩试验。本文介绍了用于桩测试的实验装置，具有载荷施加机制和内置光纤应变仪的独特功能。描述了用于解释桩载荷数据的新过程，尤其是用于提供桩位移的精确解释的新过程。
