【摘要】 为了促进中国道路工程学科的发展,系统梳理了国内外道路工程领域(包括路基工程、路面工程、公路支挡结构、道路几何设计)的学术研究现状、热点前沿、存在问题、具体对策及发展前景。首先对路基沉降变形特征、拓宽路基沉降控制、路基稳定性分析方法、特殊土路基处治技术等进行了综述;并对沥青及其混合料、水泥混凝土路面和多年冻土地区路面分别进行了分析;同时基于支挡结构特点,对公路常用支挡结构的适用条件、加固原理、设计计算理论等研究成果进行了总结;最后对道路智能选线及3D道路设计技术、道路交叉设计、面向路线设计的汽车行驶特性预测技术、路线设计质量评价技术等新理念、新技术进行了剖析,以期为道路工程学科的学术研究提供新的视角和基础资料。更多还原

【Abstract】 In order to promote the development of China’s road engineering subject,the academic research status,hot issues,existing problems,correspondent countermeasures and development prospects about road engineering at home and abroad(including subgrade engineering,pavement engineering,highway retaining structures,road geometric designs) were studied systematically.Firstly,subgrade settlement and deformation characteristics,settlement controls in subgrade widening,subgrade stability analysis methods,and special subgrade treatment techniques,etc.were reviewed.Secondly,asphalt and its mixtures,cement concrete pavements and pavements in permafrost regions were analyzed respectively.Then based on the characteristics of retaining structures,the application conditions of highway retaining walls,their strengthening principles,the calculations in their designs and so on were summarized.Finally,new ideas and techniques in the intelligent alignment selection,3D road design technology,designs of road intersections,vehicle driving characteristics prediction technology for route designs,alignment design quality evaluation technology,etc.were dissected.Hopefully,the research can provide new perspectives and basic data for the academic researches on road engineering subject.更多还原
