摘要

以双兰线沿线河流水毁冲刷情况为工程背景，在分析水毁成因机理和现场数据基础上，利用CFD数值模拟等手段，对应急性水工保护结构——石笼展开优化设计，设计3种不同形状的石笼并完成几何建模，在Fluent中利用VOF模型计算分析它们在淹没水域中的抗冲刷表现，从水流速度、石笼表面压力分布、水流阻力、床面剪切力这几个方面进行评价，以找出抗冲刷效果最好的石笼形状。最后完成水工保护结构的优化并针对不同结构进行适宜性分析。

Abstract

Taking the situation of the scour of water damage along the Shuanglan crude oil pipeline as the engineering background

this paper discussed how to optimize the hydraulic protection structure. Based on the analysis of the mechanism of water damage and site data

CFD-based numerical simulation and other methods were adopted to optimize the design of the gabion as an emergency hydraulic protection structure. Three different gabion structures were designed and their geometrical models were constructed. The VOF model was used in Fluent to calculate and analyze their anti-erosion performance under water. Various factors including water-flow velocity

surface pressure distribution on gabion

flow resistance and bed shear stress

were evaluated to find the gabion structure with the best anti-scouring effect. Finally

the optimization of the hydraulic protection structure was completed and the suitability of each structure was analyzed. The results obtained in this study can not only provide guidance for the design of hydraulic protection works for the Shuanglan crude oil pipeline

but also have implications for similar water damage hazard prevention and control projects.
