泄洪

In this article, I share several tested, practical design concepts for spillways and stilling basins.

在此，我做了很多测试，为泄洪和st固定基础理论概念。

As for the excavation of the sand-gravel zones,except the toe slab and its 1/9 bottom width down stream,the alluvial layers are excavated to the micro-weathered rocks,while the other sections remain unexcavated.

闸门利用水力和杠杆原理实现自控关闭；闸坝平时挡水发电，洪水期自动翻倒泄洪冲砂，有效地解决洪水对上游库区实物的淹没损失及水库泥沙淤积问题；闸坝采用地下混凝土连续墙进行地基防渗处理及面流消能，消能效果显著，工程投资少。

On the basis of model test, a 3 D numerical simulation on the flow field of low waterhead and big discharge riverbed hydroelectric station was made by adopting k-ε turbulence model and VOF method.

在1∶100水工模型试验的基础上，应用k-ε流数值模型，采用VOF方法，对低水头大流量河床式电站大坝泄洪流场进行了三维数值模拟。

The local intensive rainfall caused by flood discharge atomization in downstream reach of Goupitan Hydropower Project is studied by 1∶55 physical model test and engineering analogy,the rainfall intensity and its influene area are forcasted.

通过1∶55的物理模型试验和工程类比分析，对构皮滩工程大坝泄洪雾化引起下游局部强降雨进行了研究，并对降雨强度及影响范围进行了预测。

As the center of Katrina passed east of New Orleans on August 29, 2005, the storm surge caused more than 50 breaches in drainage canal levees and also in navigational canal levees and precipitated the worst engineering disaster in the history of the United States.

颶風卡崔娜对新奥尔良的影响是毁灭性的和深远的。2005年8月25日，当飓风卡崔娜的中心穿越新奥尔良东边的时候，风暴的冲击在泄洪和导航的渠道上造成了五十多处的决堤，酿成了美国历史上最为严重的工程灾难。

In the process, they were replacing street surfaces, sewer connections, storm drains, catch basins, gas lines and whatever else they inadvertently dug up with their backhoes.

在这个过程中，他们重铺了街面，下水道，泄洪管，储水池，输气管道以及一切他们挖掘机有意无意挖到的东西。

In This paper, it is discussed that how to establish risk-analysis indexes system of flood discharge structures for concrete dam based on lack of monitoring data, and how to measure the flood discharge risk furtherly.

因此，本文就如何在监测资料缺乏的情况下建立混凝土大坝的风险指标体系进行了探讨，重点对泄洪系统中的水力风险进行了研究。

The investigated results indicate that arch slab has a good stable condition and is suitable for large flood discharge of high arch dam.

研究表明：拱形底板具有整体稳定性特征，它可能是高拱坝大流量泄洪水垫塘比较理想的保护型式。

Three dimension and turbulent are common characteristic of fluid flow problem in nature and added free surface for the best familiar fluid-water, such as flood discharge flow around frusta of brake in waterpower project, flow around hull in ship engineering, and so on, all have the three characteristics which are the very important study content and aspects in CFD.

摘要自然界中的流体流动问题一般都具有三维性和湍动性，对于最常见的流体—水则同时还拥有自由表面，水利工程中绕闸墩的泄洪水流、船舶工程中的船体绕流等均具有上述流动的三种特性，这三种特性是计算流体力学领域非常重要的研究内容和方向。

On the basic of above job a mathematical model of simulation turbulent flow with free surface is established and triumphantly applied to numerical computation on 2D spillway and 3D spillway with frusta of brake.

自然界中的流体流动问题一般都具有三维性和湍动性，对于最常见的流体—水则同时还拥有自由表面，水利工程中绕闸墩的泄洪水流、船舶工程中的船体绕流等均具有上述流动的三种特性，这三种特性是计算流体力学领域非常重要的研究内容和方向。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
