Abstract

Analysis and design with simple correlations are always of interest to engineers. Predicting the bearing capacity of a spudcan in a multi-layered clay soil is one of the challenges facing jack-up designers and the installation process. In this paper, simple correlations are presented for the prediction of the bearing capacity–penetration curve of the spudcan using numerical modeling results and analyzing the parameters affecting the bearing capacity of a spudcan in a multi-layered clay soil. Multivariate regression was used to obtain these correlations and their quality was evaluated by comparing the numerical modeling results to the prediction correlations. Moreover, some examples were solved using data obtained from previous research and the resultant curves were compared with the reference curves. The results showed that the presented correlations had good accuracy in predicting the bearing capacity of spudcans in various profiles of multi-layered clay soils.

摘要

工程师总是对具有简单相关性的分析和设计感兴趣。预测桩柱在多层粘土中的承载能力是自升式设计人员和安装过程面临的挑战之一。在本文中，使用数值模拟结果和分析影响多层粘土中桩柱承载力的参数，提出了用于预测桩柱承载力-渗透曲线的简单相关性。多元回归用于获得这些相关性，并通过将数值建模结果与预测相关性进行比较来评估其质量。此外，使用从先前研究中获得的数据解决了一些示例，并将所得曲线与参考曲线进行了比较。
