查询词典 reinforced concrete

Therefore,the permeability of concrete plays an important role in durability of concrete.

因此混凝土渗透性能在混凝土耐久性方面起着非常重要的作用。

According to the experience gained in traditional penetrating tests, this thesis has produced a high-pressure clay permeameter and discussed the instruments testing principle, measuring method and derivation of the calculation formula in details. Meanwhile, plenty of testing research has been done by taking an example for the permeability coefficient measuring of plastic concrete and the influencing factors of tests to the permeability coefficient of plastic concrete measured by this instrument have been analyzed.

3本文根据常规渗透试验中积累的经验，自行研制了一种高压土工渗透仪，对该仪器试验原理、测定方法以及计算公式的推导进行了详细的探讨，并以塑性混凝土渗透系数的测定为例进行了试验研究，对使用该仪器测定塑性混凝土渗透系数时影响渗透系数的试验因素进行了分析。

A lab test apparatus was developed into evaluating the noise reduction of the porous cement concrete. A constant head permeameter was developed to ascertain the water permeability of porous cement concrete, the influence of the porosity and pore size on the water permeability was studied.

另外，对多孔水泥混凝土的透水性能进行了研究，通过建立有效孔隙率、孔径大小与渗透系数的关系，结合其实际透水性能，得出了满足一般排水性路面排水要求的有效孔隙率范围和级配。

But it is not good with high prestress level. This paper consider permissible tensional prestress value from three aspects to avoid tensile crack on concrete、interface bonding between concrete and CFRP and disadvantage failure mode of CFRP broke before steel yield.

但是，CFRP片材的张拉预应力值并不是越大越好，本文从三个方面出发考虑了预应力CFRP增强RC梁的容许张拉预应力值，避免了张拉预应力值过高产生的混凝土拉裂缝产生、混凝土与CFRP之间界面剥离和CFRP先于钢筋破坏这种不利破坏模式的发生。

The concrete strength reach 25 grade, and it's high in pervious concrete.

本文主要介绍透水混凝土的研制和应用过程。

Pervious concrete is of good perviousness,it can release the problems of highway seeper and urban environment,so it is a sort of environmental protection concrete. Through comparison test of performance of mixtures with different single particle size,the result indicates that mixing single particle size mixtures is of a good many advantages.

透水混凝土具有良好的透水性，能够缓解公路积水和城市环境问题，是一种环保型的混凝土，通过对不同单粒径混合料的性能进行比较试验，结果表明，将单粒径混合料进行混合具有很多优点。

The usual method of testing concrete may test and destruct a phototype only once and can not define the position,scope of drawbacks of concrete.It also can not demonstrate the extent of structure damaged by the method.Nondestructive testing can abandon these shortcomings.So it is valued and applied in the engineering practice.

常规的混凝土检测采用破损检测，它只能对同一试件进行一次测试并损坏试件，而且无法检测出混凝土内部缺陷的位置与大小，也不能判断结构物遭受破坏的程度等，而无损检测方法可避免这些不足，因此在工程实际中日益得到重视和应用。

And New York's rebellion called to me excitedly, this savagery which piled great concrete block on concrete block, topping at the last moment as in an afterthought, with crowns as delicate as pinnacled ice; this lavishness which, without a prayer, pillaged coal mines and waterfalls for light, festooning the great nature-severed city with diamonds of frozen electrical phenomena─ it fascinated me, the Asian man, and in it I saw not Milton's Satan, but the one of Blake.

而纽约的反叛精神激动着我的心。它的野性将大块混凝土层层垒起，在最后一刻仿佛踌躇再三才加盖，顶部皆似精巧的冰山；它的挥霍未经祈祷便为获取光明劫掠煤矿和瀑布，用钻石般璀璨夺目的无数电灯装饰这座超脱自然的伟大城市──这一切令我，一个亚洲人心醉神迷。在纽约身上我看到的不是弥尔顿笔下的撒旦，而是布莱克的撒旦。
