摘要

本文在重力型海上平台模型的基础上，对流动对无黏性和粘性土壤侵蚀的影响进行了数值模拟。发生侵蚀的介质的运动用纳维-斯托克斯方程来描述。在粘性土壤侵蚀的情况下，介质被认为是一种双组分流体，其中一组分的粘性更大，密度更大，模拟了浸水土壤的行为。介质被认为是均匀的无黏性土壤，侵蚀发生的固体颗粒的运输。给出了三维问题的计算结果。

Modeling cohesionless and cohesive soils erosion near oil platforms of gravity type

This paper presents numerical simulation results of the flow effect on the cohesionless and cohesive soils erosion at the base of the gravity-type offshore platform model. Movement of the medium in which erosion occurs is described by Navier-Stokes equations. The medium is considered to be a two-component fluid in the case of the cohesive soil erosion, one component being more viscous and dense and simulating the soaked soil behavior. The medium is considered to be homogeneous for the cohesionless soil, the erosion occurring by the transport of solid particles. The results of calculations for three-dimensional problems are presented.
