i-SDEPCI海上风电桩基冲刷检测分析系统的设计与实现

Design and Implementation of i-SDEPCI Offshore Wind Turbine Pile Erosion Detection and Analysis System

由于海洋环境条件复杂,动态冲刷情况下的冲刷量计算分析系统研发处于空白,且手动计算冲刷量较为繁琐,无法满足日益增长的海上风机基础维护需求。基于TIN的冲填量计算方法,实现i-SDEPCI海上风电桩基冲刷检测分析系统,可便捷开展海上风电桩基冲填计算分析等工作。通过在江苏滨海南H3#风电场的应用,计算结果与南方CASS的计算精度基本一致,平均误差为-2.12 m3,均方根误差为5.09 m3,相对误差百分率为1.54%,决定系数R2为0.998,可用于海上风电工程单桩基础及多桩基础冲刷检测相关工程计算。

Due to the complex Marine environmental conditions,the research and development of the brush volume calculation and analysis system in the case of dynamic scour is blank,and the manual calculation of the brush volume is cumbersome,which cannot meet the increasing needs of offshore fan foundation maintenance.The TIN-based filling capacity calculation method implements the i-SDEPCI pile foundation erosion detection and analysis system for offshore wind power,which can facilitate the calculation and analysis of pile foundation for offshore wind power.Based on the application in the South H3#wind field of Binhai,Jiangsu Province,the calculated accuracy of CASS is basically consistent with that of CASS in South China.The average error is-2.12 m3,the root mean square error is 5.09 m3,the relative error percentage is 1.54%,and the coefficient of determination R2 is 0.998,which can be used to calculate the scour detection of single pile foundation and multi-pile foundation in the offshore wind power engineering.
