摘　　要：基于slide软件,采用刚体极限平衡方法(Bishop法)与数值模拟技术,研究土工织物与充填袋对海洋风力发电基础结构安全系数影响。为提高研究的可靠性,设立4种不同水位,其中每种水位工况又设立了6种工况。结果表明,充填袋与土工织物的使用提高了海洋风力发电基础结构的安全性,土工织物较充填袋对海洋风力发电基础结构稳定性的提高更为明显,两者结合起来对结构安全系数的提高要高于单独作用对风机基础结构安全系数的提高。在分析中,充分考虑了不同地质层的力学参数差异以及各部位的力学性能,对工程实际具有一定的指导意义。Based on the slide software, the influence of geotextile and filling bag on the safety factor of the offshore wind power infrastructure is studied by using the rigid body limit equilibrium method （Bishop Method）. In order to improve the reliability of the study, 4 different design water level conditions were established, and each water level condition was set up in 4 kinds of working conditions. The results show that the use of filling bags and geotextile improves the safety of the off- shore wind power infrastructure. Compared with filling wind power infrastructure stability, the combination of bag, geotextile is more obvious on the marine structural safety coefficient is higher than that of single action to improve wind turbine structure safety coefficient increases, In the analysis, the mechanical parameters of different geological layers and the mechanical properties of each part are taken into account. It has certain guiding significance to engineering practice.
