摘　　要：随着PCPT技术在海洋地质勘察中广泛应用,使基于该技术的SRD在钢桩的可打入性分析中的应用成为可能.参考Doyle研究的墨西哥湾的4个TLP平台粘性土SRD的结论,结合API规范对砂性土打桩阻力的规定,组合成一种新的SRD计算方法.文中论述的2种SRD计算方法可供南海TLP项目打桩分析参考.PCPT is commonly applied in offshore geotechnical investigation in China, and the SRD method based on this technology is preferable to analyze the drivability of piles . According to the four TLPs in the Gulf of Mexico studied by Doyle, a recommended factor for SRD in clay soil figured out. Combined with the SRD method in API for cohesion less soil , an integrated S R D method is completed. These two SRD methods mentioned in the paper could provide a reference to the analysis of drivability of piles for further TLP projects in the South China Sea.
