摘要

深水高桩承台基础结构柔，长期处于深水激流恶劣工作环境中，对其进行准确而有效的损伤分析非常重要。首先对深水高桩承台基础受力变形特征进行分析，找出单桩损伤与弯矩曲率的关系，在Park‑Ang的双参数损伤模型基础上建立了适用于深水高桩承台基础损伤曲率模型，并给出5种损伤程度的定量描述；应用美国加州大学伯克利分校的钢筋混凝土试件损伤模型试验结果进行分析和比对，验证了损伤曲率模型的损伤程度划分是符合桩基实际受力变形损伤的，最后通过工程实例的实践应用验证了损伤曲率模型的可行性和工程适用性。

Abstract

Due to the soft structure and long-term exposure in the harsh working environment of deep water

the deep water high pile cap foundations are prone to damage. Accurate and effective damage analysis on the high pile cap foundations is important. Firstly

authors analyzed the deformation characteristics of the deep water high pile cap foundations and found the relationship between the damage and the curvature of bending moment of a single pile. Then the damage curvature model suitable for deep water high pile cap foundations is established

and a quantitative description of five damage degrees is given based on Park-Ang's two-parameter damage model. The reinforced concrete specimens damage test results between the University of California at Berkeley and the damage analysis model proposed in this study are analyzed and compared. It is verified that the damage degree of the damage curvature model proposed in this paper is consistent with the actual stress deformation of the pile foundations. Finally

the feasibility and engineering applicability of the damage curvature model are verified by engineering examples.
