【摘要】 海岸防护工程是海岸工程的重要组成部分,以海岸防护(或海滨防护)为目的,建造不同类型的海岸建筑物,护岸是其中的一种。波浪荷载是护岸结构的主要荷载之一波浪对护岸的作用主要包括波浪对护岸结构的冲击压力、浮托力等。本文应用计算流体力学软件FLUENT为工具,进行了波浪作用下透水型护岸—碎石聚氨酯结构护岸的特性分析的数值模拟。在波浪模拟的部分采用推板造波的原理,加载UDF设置动边界参数实现对推板造波的模拟,生成了规则波浪。研究透水型护岸结构与多孔介质结构之间的关系在FLUENT中用多孔介质等效代替这种护岸结构,则波浪作用下透水型护岸的受力的数值模拟可以用波浪与多孔介质的相互作用实现,建立波浪与多孔介质相互作用的耦合数学模型,设置多孔介质的参数实现了对于透水型护岸结构的模拟。为了研究护岸在波浪下的受力情况,在护岸坡面上设置一定数量的监控点,监控特定点上的波压参数,为了研究生成的波浪数据则在波浪生成区域设置监控线充当浪高仪的功能输出了波浪数据,分析不同水深不同波浪要素条件下护岸受力的特点给出护岸坡面受力、波浪爬高和反射率随波浪要素变化的关系、和流场、压力场、速度场的特点。更多还原

【Abstract】 Coastal shore protection projection is an important part of the shore projection, For the purposes of coastal protection (or coastal protection), We construct different types of marine coastal buildings or take other protective measures. Revetment is one of them.The wave force is main loading on the revetment structure.The main function of the wave to the bank protection revetment structure, including the surge pressure of waves on,buoyancy and so on.In this thesis, research the permeable revetment structure-Elastocoast under the wave action in the numerical simulation using computational fluid dynamics software FLUENT.in the physics wave generating imitating method study,the research subject was push plate wave maker which was main component in the real tank, loading UDF and set the dynamic mesh parameters to achieve the dynamic push plate wave simulation and generated regular waves.Research the relationship between permeable revetment structure and porous medium,used equivalent porous medium instead of this revetment structure in FLUENT, set up a mathematical model establishment of wave and porous media. set the coupling parameters of porous medium for the realization of the Simulation of porous media. For the study of the forcs of revetment under the waves, set some number of monitoring points on the surface of the slope to monitoring a specific point on the wave pressure parameter, in order to discuss the date of waves generated,in the wave field settings some control line as wave instrument to output of the wave function of the data, analysis the slope characteristics of the force of different elements of different wave conditions、water depth slope.gives the force relationship in different elements and the characteristics of wave and flow field、pressure field、velocity field更多还原
