海洋工程中灌浆连接段若干规范比较
Comparison of Several Design Specifications for Grouted Connections in Marine Engineering
-
摘要:
灌浆连接是海洋工程中最常用的连接方法之一。文章比较了其适用的五部规范及推荐做法：英国健康与安全执行局《海上结构桩与套管连接技术报告(HSE-Pile/sleeve connections—2001)》，美国石油协会《海上固定平台规划、设计和建造的推荐做法(API RP 2A-WSD—2007)》，国际标准化组织《石油和天然气行业固定海上钢结构规范(ISO 19902—2007)》，挪威的石油技术法规《钢结构设计规范(NORSOK-N-004—2013)》，挪威船级社《海上风机结构设计规范(DNV-OS-J101)》，给出了上述规范的验算方法及适用范围。由于灌浆连接段在使用中的受力形式不断复杂化，本文进一步研究了规范《DNV-OS-J101》的发展历程，为该行业的设计人员理解该规范验算方法概述及适用范围的发展提供了帮助。 Abstract:The grouted connection is one of the mostly commonly used joint in marine engineering. This paper compares five specifications or recommended practice used for design of grouted joint in offshore wind turbines foundation. They are Offshore Technology Report from UK Health & Safety Executive (HSE-Pile/sleeve connections-2001); Recommended Practice for Planning, Designing and Constructing Fixed Offshore Platforms—Working Stress Design from American Petroleum Institute (API RP 2A-WSD—2007); Petroleum and natural gas industries —Fixed steel offshore structures from International Standard (ISO 19902—2007); Design of steel structures from NORSOK STANDARD (NORSOK-N-004—2013) and Design of Offshore Wind Turbine Structures from Det Norske Veritas(DNV-OS-J101). The outline of the checking method and the applicable scope of the specification or recommended practice above is summarized. Furthermore, because of the increasing complexity of the loading condition for grouted connections, this paper gives a development process of DNV specifications, which could help designers to understand the evolution of this specifications in its checking method and applicable scope.
