查询词典 pavement

Computation results show that, for the uncracked pavements, low-temperature contracted cracking is not occurred generally, but the temperature-fatigue cracking is able to occur in pavement because of cyclical temperature varying.

在此基础上，对路面温度应力以24小时为周期的变化特征进行了系统的分析，发现了初始应力对周期性变化的路面温度应力场的影响，并提出了采用多周期迭代计算解决这一问题的有效途径。

Hastily straightening his glasses and unsticking his cheek from the glass, he pressed his nose against the window instead and squinted down at the pavement.

他赶紧扶正了眼镜，把脸从玻璃窗上移开，而把鼻子贴了上去，向斜下方的人行道看去。

The mules and donkeys taking farmers' produce to the markets; the old parts of the town with their untarred streets and little houses; the street vendors whose call you could hear from my room; the friendliness of the people, their curiosity about the laowai; the bicycles, the bicycles, the bicycles; the dark nights when there was a power-cut and you cycled home in the freezing cold by the dim light of the moon; the explosive sounds announcing the arrival of the pop-corn man with his corn-popping cylinder and his portable coal stove; the fascinating street of metalworkers where you could watch the craftsmen at work; the women squatted beside the road making their own knitting needles out of bamboo twigs; the baicai laid out on the pavement and the sliced aubergines hanging from the washing lines to dry...

驴子和骡子把农民的产品运到了市场，老城区是还未硬化的路面和矮小的房子，你在屋里就可以听见街上商贩的吆喝声，友好的人们和他们对老外的好奇；自行车、自行车，还是自行车；停电的晚上冷得彻骨，你借着模糊的月光骑车回家；砰砰的声音宣告着卖爆米花的商贩的到来，带着他用来爆米花的气锅和便携式的煤炉；铁匠一条街令人着迷，你看见工匠们在忙碌；妇女们蹲坐在路边用嫩竹枝做成自己的编织针；白菜摆在人行道边，成条的茄子在晾衣绳上风干

The high temperature field did not make tensile stress and shear stress of upslope pavement increase, but it made the flexure of surface rise.

The result notes that dynamic triaxial test preferably simulate the actual stress state of grading macadam, and Uzan model which considers the shear performance of material can better reflect stress states of grading macadam. Regression coefficients of the model obviously present nonlinear characteristic with moisture changed, and to further influence dynamic resilient module.More the module is larger, more diminishing rate of maximum tensile stress on pavement Bottom is smaller. To enhance draining function and strength, the gradation should been rigid controlled, and which the content of less than 0.075mm is controlled between 5～7％ and spring-back is controlled between200~300MPa are appropriate.

结果表明，动三轴试验较好地模拟了级配碎石层的实际受力状态；Uzan模型考虑了材料的剪切性能，更能反映了级配碎石在隧道路面中应力状态；随含水量的变化，Uzan模型中回归系数变化呈明显的非线性特征，进而显著影响级配碎石的动态回弹模量的变化；级配碎石模量越大，路面层底的最大拉应力减小率越小；为了兼顾到级配碎石层的排水渗透功能和强度，应严格控制级配，特别是0.075mm以下的含量宜控制在5％～7％，级配碎石的回弹模量宜控制在200～300MPa之间。

Disturbing the lichen-coated and varnished rocks known as desert pavement can leave a visible impact for hundreds of years.

破坏长青苔层的岩石造成的显著破坏会持续长达数百年，废弃的公路就是明例。

It discusses the daily drainage design from system,tube materials,appendix,venthole, tube layout and pavement as well as rain-water drainage,and analyzes problems which should be noticed during drainage design,so as to improve the general designing level of ours.

对日常的排水设计从系统、管材及附件、通气管、管道布置及敷设和屋面雨水的排出等方面进行了论述，并分析了设计中应注意的问题，以完善和提高整体设计水平。

Vicissitudinary changes of temperature and humidity can easily induce shrinkage cracks,and sometimes these cracks reflect to surface of asphalt pavement.

但从多年的实际应用来看，这种水泥稳定碎石在温度或湿度交替变化时容易发生收缩裂缝和干缩裂缝，当沥青面层较薄时，这些裂缝会反射到面层，形成反射裂缝。
