摘　　要：海生物是固定平台设计时必须考虑的因素,针对我国南海部分平台实测海生物厚度超过设计值的现象,介绍了导管架平台考虑海生物的质量以及环境力的计算方法。以我国南海某平台为例,根据最新海生物检测结果,结合其他平台检测数据预测海生物生长速度,计算不同的海生物清理方案对导管架结构强度及基础承载力的影响,进而根据计算结果给出合理的海生物清理方案,保证平台结构安全。分析结果可供后续平台定期监测海生物生长状态及结构应力时参考,对于其他平台也具有一定的借鉴意义。Marine growth must be considered in the design of fixed platforms.Survey results show that marine growththickness exceeds design value in some platforms in South China Sea. In the paper,the calculation method of marine growth weight and environmental force for jacket platform was introduced. Based on latest survey results and prediction of marine growth thickness of other platforms in South China Sea,the influence of different marine growth removal planson jacket structural strength and pile foundation capacity was investigated. According to analysis results,a reasonable marine growth removal plan was proposed to ensure safety of platform structure. The results in the paper can be used as a reference for monitoring marine growth status and structural stress.
