Abstract Helical piles are used mainly to resist tension forces generated by uplift and overturning moments of various structures, therefore they have been suggested as a potential alternative to driven piles as offshore pile because they provide a large uplift capacity due to the anchor effect of the helix. To date no standards are available for the assessment of the use of helical piles in the offshore environment. State-of-the art installation and uplift capacity assessment is based on field onshore tests on small helical piles. The purpose of this review is to critically evaluate the current knowledge on helical piles considering uplift capacity, cyclic load, installation torque models and the parameters affecting the installation torque, to understand whether they can be considered for potential offshore applications. The paper could be of valuable interest for engineers and contractors involved in the offshore installation of piles.

螺旋桩作为一种潜在的海上基础系统的行为综述

摘要 螺旋桩主要用于抵抗由各种结构的抬升和倾覆力矩产生的拉力，因此，由于螺旋桩的锚固效应，螺旋桩提供了较大的抗拔能力，因此被建议作为海上桩打入桩的潜在替代方案。 . 迄今为止，还没有可用于评估在海上环境中使用螺旋桩的标准。最先进的安装和提升能力评估基于对小型螺旋桩的现场陆上测试。本综述的目的是批判性地评估螺旋桩的当前知识，考虑提升能力、循环载荷、安装扭矩模型和影响安装扭矩的参数，以了解它们是否可以考虑用于潜在的海上应用。
