摘要

针对海上漂浮式光伏开孔重力式基础的水平承载性能展开相关研究

采用数值分析和离心机模型实验方法探讨黏土中开孔重力式基础的水平向承载特性

构建开孔重力式基础的水平向极限承载破坏模式

并揭示了不同接触条件下深宽比和开孔率对开孔重力式基础承载特性的影响规律。研究表明

开孔重力式基础的水平向承载模式主要表现为滑动破坏模式;在不同的开孔率、深宽和接触条件下

破坏模式又可分为整体和分体滑动破坏模式;基于破坏模式的分析最终提出可应用于开孔重力式基础的最优开孔率及水平向极限承载力的计算方法。

Abstract

This paper presents a study on the horizontal bearing performance of open-ended gravity-based foundations（OGBFs）for offshore floating photovoltaic （FPV）systems. In this study

a combination of numerical analysis and centrifuge model tests was conducted used to investigate the horizontal bearing behaviors of OGBFs in clay. The horizontal ultimate bearing failure mechanisms of OGBFs were identified

and the effects of embedment ratios

hole ratio

and various contact conditions on the bearing characteristics of OGBFs were examined. The results indicate that the horizontal bearing failure mechanisms of OGBFs is dominated by sliding failure. Under different hole ratios

embedment ratios

and contact conditions

failure mechanisms can be categorized into global sliding failure and partial sliding failure. Based on the analysis of failure mechanisms

an optimal hole ratio and a calculation method for the horizontal ultimate bearing capacity applicable to OGBFs are proposed.
