发布时间：2018-11-18 11:07
【摘要】：随着海洋工程逐步向深水发展,传统结构形式消浪结构的应用受到一定的限制,新型消浪结构优势逐渐显现。近几年,新型消浪结构的应用越来越引起人们的重视,因为它不破坏水域的整体性和生态环境,不改变水流和泥沙运动条件的特点,特别适合需要消浪的深水水域。随着我国经济快速发展,汽车数量不断增多,废旧轮胎的回收利用问题越来越严重,考虑到轮胎比较经久耐用、绿色环保,因此对一种由废旧轮胎组成的半潜式的新型消浪结构的研究不失为一种前沿性的研究。在海洋消浪结构中对废旧轮胎为主要材料的半潜式结构的应用研究比较少见,因此为了了解半潜式废旧轮胎结构的消浪特性,掌握影响其消浪效果的因素,针对相对宽度、相对入水深度、相对水平净间距、垂直净间距、排列方式等因素对消浪效果的影响进行了物理模型试验,了解在规则波作用时该半潜式结构的消浪性能,试验结果表明:透射系数在相对宽度大于0.6时随宽度的增大而减小,随入水深度的增大而减小,水平间距的影响规律不是很明显,在模型潜入水中时,单层水平情况下波陡H/L和相对波高H/d对透射系数的影响不是很大,而双层水平情况下,改变波陡H/L和相对波高H/d对透射系数的影响还是很明显的,对于单层水平情况下宽度B=2.52m时在入水深度q=0.03m时消浪效果做好,垂直排列比水平排列消浪效果最佳等。对于波浪,由于模型潜入水体表面以下的原因,能够使水表面及以下部分波浪破碎,破坏了波浪原有的运动方式,也可反射部分波浪达到衰减波浪的目的。与现有的各种浮式和半潜式消浪结构物相比,经济、可靠、取材容易。关键是消浪结构是潜入海平面以下可以在不影响旅游景点海滩整体观光效果的同时可以达到很好的消浪作用,为其能够被广泛应用提供重要依据。对海岸带防护、减小海浪对海滩的侵蚀具有重要的作用。
[Abstract]:With the development of ocean engineering towards deep water, the application of the traditional structure is limited, and the advantages of the new type of wave-absorbing structure gradually appear. In recent years, more and more attention has been paid to the application of the new wave dissipating structure, because it does not destroy the integrity and ecological environment of the water area, and does not change the characteristics of the water flow and sediment movement conditions, so it is especially suitable for the deep-water waters where wave elimination is needed. With the rapid development of China's economy, the number of cars is increasing, and the problem of recycling used tyres is becoming more and more serious. Considering that tyres are more durable and green, Therefore, the study of a new type of semi-submersible wave dissipating structure made up of used tires is a kind of advanced research. The application of semi-submersible structure with waste tire as the main material is rare in ocean wave dissipating structure. Therefore, in order to understand the characteristics of wave elimination of waste tire structure and grasp the factors that affect the effect of wave elimination, the relative width of the semi-submersible tire structure is studied. The effects of the relative depth of water, the relative horizontal net spacing, the vertical net spacing and the arrangement mode on the wave attenuation effect are tested by physical model tests, and the wave attenuation performance of the semi-submersible structure under regular wave action is understood. The experimental results show that the transmission coefficient decreases with the increase of the width when the relative width is greater than 0.6, and decreases with the increase of the depth of entering water. The effect of horizontal spacing is not obvious. The influence of wave steep H / L and relative wave height H / d on the transmission coefficient is not great in the case of single layer level, but the effect of changing the wave steep H / L and relative wave height H / d on the transmission coefficient is still very obvious in the case of double level. When the width of BX 2.52m is single layer horizontal, the effect of wave elimination is better when the depth of water is 0.03m, the vertical arrangement is better than the horizontal arrangement, and the effect of wave elimination is the best. For wave, because the model submerges below the surface of the water body, it can break the water surface and some waves below, destroy the original motion mode of the wave, and can also reflect the part of the wave to achieve the purpose of wave attenuation. Compared with the existing floating and semi-submersible wave-absorbing structures, they are economical, reliable and easy to use. The key point is that the wave elimination structure can not affect the overall sightseeing effect of tourist attractions and beaches without affecting the overall effect of wave absorption, which provides an important basis for its wide application. It plays an important role in protecting the coastal zone and reducing the beach erosion caused by the waves.
