摘要/Abstract

摘要：

采用固化土进行冲刷防护是一种全新的防冲刷措施,目前正逐步被应用于海上风力发电单桩基础及跨海大桥桩基础的冲刷修复中.流态固化土在泵送至海洋桩基周围冲刷坑中的过程中,会对既有承载力弱化的桩基产生不利影响,然而目前仍缺乏对该问题的认识.采用计算流体动力学方法,模拟了单桩基础周围冲刷坑中流态固化土泵送过程,关注流态固化土对桩基础的作用,分析了泵速、海流流速、固化土类型等因素对桩基础作用力的影响,其中海流流速影响最大,同时提出了流态固化土对桩基作用力简化分析思路,并给出了作用力经验公式.研究结果可作为固化土防冲刷工程技术控制的依据.

Abstract:

As a novel scour protection measure, the fluidized solidified slurry is pumped into the developed scour holes around the pile foundation for scour repair as the fluidized material solidifies gradually. In the process of pumping operation, the fluidized solidified slurry will have a negative effect on the pile. However, there is still a lack of comprehensive study on the force acting on the pile in this process. The CFD model is adopted to simulate the flow and diffusion of the solidified slurry pumped into the scour pit around the monopile. The effects of pumping velocity, current velocity, and material property of solidified slurry on the force acting on the pile are systematically investigated, of which, current velocity is the most sensitive factor. A simplified analysis method for force of fluidized solidified slurry acting on the monopile is proposed, providing basis for the design and construction of the pumping operation.

Key words: fluidized solidified slurry, scour protection, CFD method, offshore pile foundation, force
