摘要
在对我国南海海域进行自升式钻井平台场址工程地质调查的基础上,分析桩靴基础在上述层状土中贯入的破坏模型,提出在不同破坏模型下的插桩深度预测方法,实例验证表明,该方法可提高对插桩深度预测的准确性。
On the basis of geotechnical investigation at the spot of jack-up platform in south China sea, the failure mechanism of spud-can foundation penetration in the above layered soil was analyzed, to bring forward the prediction method of footing penetration in different failure modes. The prediction method was validated by practical example showing that it could improve veracity of footing penetration prediction.
