结构层厚度 meaning in English
laminate construction thickness
Examples
- Laminate construction thickness
结构层厚度 - At present , most of the achievements mainly focus on the measurement of pavement thickness
目前的研究成果大多局限于路面结构层厚度的检测。 - The constructionspeed of highwayincreases rapidly , at the same time , the path qualityexaminationdutyaggravatesdaybyday , andtheload ofroads evaluationalsoincreases quicklyin the maintenance . traditional method has many disadvantages , such asinefficiency , tiring , slow speed of evaluation etc . especially , the number ofmeasuring point is too little to give accurate and comprehensive result of theinterior recessive diseases of highway . beside this , the traditional method leadsdestructiontotheroadsurface , whichwillexacerbatethedeteriorationofhighway . in avoid not to affecting the normal travel and not to destroying the pavementstructure , it is urgently to apply nondestructive evaluation ( nde ) techniques tocontrol quality of highway construction and to estimate the running conditionaccurately . the nde techniques of highway have to satisfy the followingqualification : mapping the shape , size and depth of flaw precisely ; having nodamages to the road structure ; being capable of carrying out examination in widerange ; beingeasytoequipandoperate ; beinginsulatetotheenvironmentinfluence . theintelligenceintegrationevaluationvehicleforroadbedandpavement ( iievrp ) is just the comprehensive nde technique that can satisfy the demands above , which can implement detection of highway rapidly and nondestructively
作为吉林省科技厅高新技术项目( 20020331 ) “路基路面智能集成检测车”的一个子项,本文在理论的基础上,结合实验对探地雷达检测路面结构层厚度及路基、路面病害进行了研究,主要工作如下: 1 .阐述探地雷达发展的历史和研究现状,介绍探地雷达在路面结构层厚度检测与路基、路面病害识别上的应用,分析探地雷达设备性能,探讨其测量参数对探测性能的影响; 2 .引入matlab计算软件,利用其中的小波分析工具箱对探地雷达信号进行分析处理; 3 .构建适于道路检测的车载实验平台,为进一步完善路基路面检测车系统打下了基础; 4 .通过对模型的检测,对探地雷达探测性能做出定性或半定量的评价; 5 .通过对实际路面的检测,验证探地雷达在道路检测中的有效性。 - The results showed that the gradation , which designed by volumetric methods , has perfect water - stability and other pavement performance also can meet the demands of expressway . by integrating compaction capacity and pavement performances , the optimal ratio of the structural layer thickness to the maximum particle - size is 2 . 5 . the water resistance of the mixture added amine type anti - stripping agent attenuates severely after long - term aging , but the mixture added hydrated lime not only can improve obviously the capacity of water resistance , but also has perfect long - term pavement performance
研究结果表明，采用体积法设计的级配不仅具有较好的水稳定性而且其它路用性能均满足高速公路面层的要求；综合考虑压实性能及路用性能，提出了沥青路面表面层结构层厚度与混合料最大粒径的合理比例为2 . 5 ；掺有液体胺类抗剥落剂的沥青混合料经长期老化后其抗水损害能力衰减严重，而掺加消石灰的混合料能显著提高其抗水损害能力，且长期性能较好，是一种优良的抗剥落剂。 - According to economical condition and climate condition of cangzhou , it is necessary to mention the combination and thickness of road construction that can accord the requestion of criterion , be economical and viable . author carried through different structure combination and choosed different thickness of structure layer basing on different road grade . in this text , author elected a secondary road to checking computations
按照沧州的经济条件和气候条件，提出沧州地区既符合各种规范要求又经济可行并符合当地情况的路面结构组合和路面厚度是十分必要的。作者根据不同的道路等级进行了不同的结构组合，并选用了不同的结构层厚度，同时拟定了一条二级公路进行验算。
