摘要

目的

海上风电作为清洁可再生能源的重要发展方向，对破解全球能源困局、驱动“双碳”目标进程具有深远意义，海上风电嵌岩桩基服役期间承受风、浪、流等水平循环荷载作用，其变形机理尚不明确。

方法

通过开展单轴双向水平循环荷载下风电嵌岩单桩水平循环加载现场试验，重点研究嵌岩单桩桩顶水平位移、试验桩水平位移、桩身弯矩、桩周岩石抗力及嵌岩单桩循环

曲线的演化规律。

结果

研究表明：嵌岩单桩的水平极限承载力测定值为 60 kN，随着水平分级荷载逐级增加，桩顶转角逐渐增大，呈典型的长弹性桩破坏模式；桩顶水平位移随着循环加载次数增加呈 “迅速增加－缓慢波动”变化趋势；不同埋深位置处桩身水平位移累积主要集中在前100次循环，随着循环加载次数增加，桩身水平位移累积由浅层岩体位置逐渐向深层岩体位置传递；嵌岩单桩循环

曲线变化分“弹性－弹塑性－稳定”3个阶段变化。

结论

提出嵌岩单桩在长期水平循环荷载下桩顶水平位移预测公式，可用于分析嵌岩单桩长期循环累积变形特性，基于循环

曲线构建风电嵌岩单桩循环受荷分析方法，可为现行风电嵌岩桩设计规范的优化提供理论依据和技术支撑。

Abstract

Objective

As a key pathway toward developing clean and renewable energy

offshore wind power plays a vital role in mitigating global energy shortages and advancing the "dual-carbon" goals. During operation

rock-socketed foundations of offshore wind turbines are subjected to cyclic horizontal loads c

aused by wind

waves and currents; However

their deformation behavior remains poorly understood.

Method

A field test applying uniaxial bidirectional horizontal cyclic loads was conducted on rock-socketed monopiles

examining the evolution of pile head displacement

shaft displacement and bending moment

surrounding rock resistance

cyclic

curves.

Result

The experimental results indicate a horizontal ultimate bearing capacity of 60 kN for the rock-socketed monopile. Under progressively increasing graded loads

the pile head rotation angle increased gradually

demonstrating a failure mode typical of a long elastic pile. The evolution of pile head horizontal displacement with the number of cycles followed a pattern characterized by an initial rapid increase

followed by a period of slow fluctuation. Notably

the accumulation of horizontal displacement along the pile shaft occurred predominantly within the first 100 loading cycles across all monitored depths. Furthermore

the pattern of displacement accumulation transitioned from shallow to deeper rock layers as the number of cycles increased. Finally

the cyclic

curves exhibited a three-stage evolutionary process: elastic

elastoplastic

and stable.

Conclusion

This study establishes a predictive formula for estimating the pile head horizontal displacement of rock-socketed monopiles under long-term cyclic loading

thereby providing a means to analyze their long-term cumulative deformation behavior. Furthermore

a cyclic load analysis method is developed based on the derived cyclic

curves. This methodology offers a theoretical foundation and technical support for the optimization of current design codes for rock-socketed piles supporting offshore wind turbines.
