摘要

为探究地震作用下预应力锚栓式基础结构动力响应特性,以新疆某风电场为例,基于混凝土塑性损伤（CDP）模型,考虑基础与锚栓笼的相互作用,建立地基-基础-锚栓笼三维数值仿真模型,利用二次开发实现地基边界弹簧-阻尼器的黏弹性边界模拟,明晰压缩波（P波）45°斜入射与剪切波（SV波）临界角30°斜入射作用下风电基础与锚栓笼的动力响应规律。结果显示,在地震荷载作用下,基础顶部与灌浆层的接触面以及锚板与基础底部的结合区域,应力集中现象较为突出,为损伤的高风险区域;相较于P波,基础损伤破坏对近断层脉冲SV波的敏感性更强;斜向入射导致锚栓笼内侧锚栓承受了较大的应力,对风电基础安全影响更大。因此,风电工程抗震设计中应考虑近断层脉冲SV波对风电基础的影响,确保其在极端地震事件中的安全性和可靠性。

Abstract

In order to explore the dynamic response characteristics of prestressed anchor bolt infrastructure of wind turbines under earthquake action, taking a wind farm in Xinjiang as an example, based on the concrete damaged plasticity model and considering the interaction between foundation and anchor and bolt cage, a three-dimensional numerical simulation model of foundation-base-anchor bolt cage was established, The viscoelastic boundary simulation of foundation boundary spring-damper was realized by secondary development. The dynamic response rules of wind turbine foundation and anchor cage under P wave 45° oblique incidence and SV wave critical angle 30° oblique incidence are clarified. The results show that stress concentration is more prominent in the contact surface between the top of foundation and the grout layer and the joint area between the anchor plate and the bottom of the foundation under seismic load, which is a high-risk area for damage. Compared with P wave, foundation damage is more sensitive to SV wave near fault pulse. Oblique incidence causes the anchor bolt inside the anchor cage to bear greater stress, which has a greater impact on the safety of fan foundation. Therefore, the effect of near-fault pulse SV wave on wind power foundation should be considered in the seismic design of wind power engineering to ensure its safety and reliability in extreme seismic events.
