围堰

The in-water main piers of Sanmenjiang Bridge are elevated pile cap s that were constructed by steel hoisting box cofferdams.

三门江大桥水中主墩系高桩承台，采用钢吊箱围堰法施工，利用简易的型钢拉压柱作为吊箱的吊挂结构，将吊箱吊挂在钻孔桩钢护筒上，施工操作简便，降低工程成本，是一项值得推广和应用的施工技术。

Seaside silt is always under periodical effect of wave and tide. Cofferdams and back berms are often built in the two sides of a roadbed for convenient construction, resulting in obstructing wave but letting tide come into the top of the silt roadbed through drainage layer, which have great influence on the consolidation process.

海滩区淤泥长期受周期性的波浪和潮汐作用，在淤泥路基排水固结处理前，为便于施工，一般在两侧填筑围堰，并修建反压护道，波浪作用被阻隔，而潮汐通过排水层进入淤泥路基顶面，对淤泥路基的排水固结过程产生重要影响。

As the HiLoad unit is being deballasted and begins moving towards the tanker bottom, seals meet the hull to form six closed compartments, or cofferdams.

正如HiLoad单位正在deballasted并开始走向加油机底部， SKF进口轴承海豹满足船体形成六个封闭舱室，或围堰。

This article mainly,in light of the construction of the Xiangfan-ChongqingⅡLine running water river bridge, introduces the adoption of steel casings as cofferdams for submarine pile extension when 4#-3 deepwater bored pile s have broken piles within the steel casings between the river s surface and the river s bed.

以襄渝Ⅱ线流水河大桥施工为例，重点介绍了4号-3深水钻孔桩在河水面以下、河床面以上的钢护筒内断桩后，采用钢护筒做围堰进行水下接桩的处理方法。

Taking the construction of the elevated pile caps in deep water for main piers of Minjiang River Bridge on the newly-built Fuzhou-Xiamen Railway as an example,this paper presents the optimal design of the steel boxed cofferdam structures on the basis of mechanical analysis of the cofferdams subjected to different load cases.

以新建铁路福厦线闽江特大桥主墩深水高桩承台施工为例，介绍通过钢吊箱围堰各工况的受力分析，进行优化设计钢吊箱结构。

To build the sheet-pile quay-wall on the soft foundation with relative low allowed bearing capacity may decrease volume of earthwork and problems such as cofferdam construction, etc.

在地基允许承载力较低的软基上修建板桩码头，可减少土方工程量及解决工程施工围堰困难等问题。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
