highway grading meaning in English
公路整型
Examples
- The discussion of highway grade separation design
公路互通立交设计探讨 - The discussion of comprehensive designing for highway grade separation of mountain areas
浅谈山区高速公路互通立交总体设计 - Thus the simulation system based on the model can describe rather complicated traffic states on multi - lanes highway and indicate traffic capacity of different highway grade
从而能够描述多车道公路上比较复杂的交通状况，表示不同道路等级的通行能力。 - A recommend value of appropriate roadbed height is put forward according to the sand dune type and the highway grade , make investigation to the sand harm and other problems of built highways in desert areas gathering the related materials of present day highways , and then make comprehensive and systematic statistics to related data and racious factors which affect the roadbed height ; analy the suitable roadbed height for the windblown sand drift passes through smoothly according to the open country windblown sand field test ; test and verify the outcome according to indoor wind tunnel test ; finally a appropriate recommend roadbed height value will be put forward for different grade highways in different areas , which is according to the analysis of roadbed stability the roadbed height economic analysis and different use requirement to different grade highways
收集现有沙漠公路的有关资料，对全国已建沙漠公路进行沙害及其他病害调查，对相关数据和影响沙漠公路路基高度的各种因素进行综合系统地统计分析；通过野外风沙流场测定，分析适宜风沙流顺利通过的路基高度；通过室内风洞试验进行验证；结合路基稳定性分析、路基高度的经济性分析，考虑不同等级公路的使用要求，最终提出不同地区不同等级沙漠公路路基填土高度的合理高度建议值。 - It is also the key factor to improve the highway grade in these areas . the sand harm usually happens and the roadbed is obviously influenced by the sand foundation stability condition and the groundwater if the roadbed earthfill height is low . on the contrary , the wind erosion usually happens if the height is high
公路路基的合理高度是保证沙漠公路不产生沙害的主要因素之一，同时是提高沙漠地区公路等级的关键，沙漠公路路基填土高度低，则易出现沙埋病害，路基受沙漠地基稳定状况及地下水的影响显著，反之，则易出现风蚀病害，并存在高填方路基和稳定性问题，工程造价相应增加。
