海上风电机组基础灌浆技术应用与发展

Grouting Technology Application and Development in Offshore Wind Farm

摘要: 海上风电灌浆是影响海上风电发展的一项重要技术，由于风机设备的长期动力载荷作用，使得海上风电的灌浆无论是灌浆材料、连接段类型、受力机理等多方面都与常规海洋工程有所不同。海上风电机组基础灌浆具有高终强、高早强、抗疲劳、抗离析等优越性能，本文简述了海上风电场对灌浆材料的要求，详细介绍了单桩基础与导管架基础这两类典型的灌浆连接段类型及其各自的工程应用和发展，最后简述了灌浆病害的监测与修复，并对海上风电灌浆技术进行展望与总结。

Abstract: Offshore grouting is an important technology impacting the offshore wind power development. Due to the long-term dynamic loading of offshore wind turbine, there is a big difference in grout material, connection type, mechanics and others compared with conventional marine engineering. Offshore wind turbine foundation grouting has superior performance of high early and final strengthen, fatigue resistant and segregation resistant. In this paper, grout material requirement was first introduced briefly. Then two typical grouted connection types of monopile and jacket as well as their engineerign application were described in detail. Finally, grout diseases's monitoring and repair was stated briefly and overview of offshore grouting technology's development was summarized.
