摘要/Abstract

摘要： 针对吸力式桶形基础负压安装渗流侵蚀效应,建立轴对称坐标下吸力桶在砂性土中负压沉贯的数值模型,应用包含土骨架、流体和液化土颗粒的三相耦合模型描述海床土体,计算负压作用下海床的渗流场分布,并模拟负压引起的渗流侵蚀过程。渗流侵蚀可改变不同区域土体的渗透率,进而引起水力梯度从内侧向外侧转移。基于孔隙水压力场的重新分布,揭示出负压安装的“安全机制”,并对安装临界吸力的变化进行评价,从而为吸力桶的安装提供工程建议。

Abstract: In order to investigate the seepage erosion effect of suction bucket foundation installation under negative pressure, the numerical model of a suction bucket embedded in sand is built in axisymmetric coordinate. A multi-phase model with soil skeleton,fluidized fine particles and water is used to describe the soil. The seepage field during suction installation is firstly calculated, and then the development process of seepage erosion caused by suction installation under negative pressure is simulated. The seepage erosion leads to different permeability values in different zones of the seabed soil, and redistributes the hydraulic gradient from internal side to external side. The “safety mechanism” during suction installation is then revealed and variation of the critical suction is evaluated to provide an advice for suction installation of buckets..
