水工

There is still a great distance the classic economic result.Component prefabrication and installation is a very important and common used work in construction,and installation is much more difficult in which while harbors or other engineering that under the water are constructed.Installation style will play an important role in the engineering cost.As a resuit,there is a great sense in researching advanced,practical,efficiency installation technique.

在港口码头及其它水工工程中，构件预制和安装是一种很常用、很重要的施工内容，其中构件的安装更是一项技术难度较大的施工内容，不同的安装方法也在很大程度上影响工程成本，因此研究先进、实用、高效的安装施工技术，具有重大的意义。

Some hydraulic structures is not the function of a single, difficult to strictly distinguish between the types, including a variety of spillway, is a water-retaining structures, is sluicing buildings; Construction of the diversion tunnel sometimes can be converted into permanent discharge or diversion tunnel, and so on.

一些水工建筑物，是不是功能单一，难以严格区分类型，包括各种溢洪道，是一个挡水建筑物，泄水建筑物，施工导流隧洞，有时可以转换为永久性放电或挪用隧道，等等。

SNEB successfully employed hydraulic engineering technology into bridge engineering construction and with its predominance of equipments and technology, SNEB was considered as a dark horse in Chinese bridge construction market.

将水工施工技术成功嫁接到桥梁工程施工中，并不断加以创新，二航局利用设备和技术优势，在中国桥梁建设市场演绎了后来居上的神奇故事。

Hydraulic model test was carried out to study the velocity distribution behind the trashrack in lateral intake/outlet of a typical pumped storage power station.

本文以某抽水蓄能电站上水库进/出水口为例，通过水工模型试验，研究了侧式进/出水口拦污栅断面的流速分布规律，着重分析了扩散段隔墩布置型式与过渡段体型对拦污栅断面流速分布的影响。

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。

After happening in a certain degree, the structure damage will have a bad effect on the load capacity and durability greatly or even cause the serious accidents. Thus, it caused not only the significant casualties and economic losses but also a very bad social influence.

水工结构在实际运营中，由于设计、施工等先天缺陷或者使用载荷超出设计以及遭受强大的突加外在荷载的作用会使结构物出现不同程度的损伤，结构发生损伤以后将严重影响结构的承载力及耐久性，甚至会发生严重的工程事故，不仅造成重大的人员伤亡和经济损失，而且还会产生极坏的社会影响。

For the shipping safety of Three Gorges Project, a physical model (1:100) experiment has been implemented from 2002 to 2003.The physical model is to evaluate the daily peaking influence on upper flow conditions for navigation and it is supposed that the Three Gorges Project have been operated 50+4 years and 70+6 years under aggrading conditions.

为了三峡工程航运安全，2002~2003 年利用 1：100 三峡库区水工模型，进行了三峡工程运行至 50+4 年和 70+6 年淤积地形条件下的电站汛期日调节对上游通航水流条件影响的物理模型试验。

The drain-pipe was bunged up with dirt, but the plumber fixed it in no time.

水管被脏东西堵住了，但水工很快就把它修好了。

Because of the huge volume of the hydraulic mass concrete, the heat of the cement hydration emits from the surface of the concrete. So a great deal of heat cumulates in the centre of the concrete, which will lead to a high and long temperature rise、 a long temperature drop period and huge amounts of temperature shrinkage.

因为水工大体积混凝土体积大，水泥水化产生的热量缓慢从混凝土表面散发出去，大量热量蓄积在混凝土内部，造成混凝土温升大，温升时间长，后期温降长，且温度收缩值大。
