Examples
- The paper is based on innumerable practical heavy - load road data , deliberate heavy - load standard in detail through theoretical arithmetic , and bring heavy - load standard about cement concrete pavement and asphalt concrete pavement separately ; in the meantime , through a large quantity of cement concrete pavement stress calculation , the paper puts forward relation expression between load on concrete board and stress level under board ; meanwhile , the paper puts forward traffic classification about cement concrete pavement and asphalt concrete pavement ; through bearing board testing on each structure sheaf the paper finds the material modulus gets modified ; through comparing position equivalent rebound modulus to theoretical equivalent rebound modulus , the paper points out limitation of nomograph in course of cement concrete pavement design , whereby , puts forward modifier formulas about theoretical equivalent modulus
本文以大量的重载道路资料为主，从实际出发，结合理论计算，对重载标准进行了详细的讨论，分别给出了水泥混凝土路面与沥青混凝土路面的重载标准了；同时，通过大量的水泥混凝土板底应力计算，推导出了混凝土面板荷载与板底应力水平的关系式；给出了水泥混凝土路面与沥青混凝土路面的交通分级；通过对试验路各结构层进行承载板测试，发现现有材料模量较以前有了明显的提高；对比现场实测的当量回弹模量与理论当量回弹模量，指出现有水泥路面设计中的诺谟图不能完全符合现有道路材料，从而提出了对理论模量的修正公式。 - The sensitivity analysis of design parameter of subgrade and pavement are used to confirmed the degree of impact on working state with change of the design parameter , it is the rational and economy that the range of design parameter are proposed . structure combination design is used to proposed basic structure of qinhuangdao ' s asphalt pavement in view of local natural environment , build material , traffic classification and soil grades . this paper puts forwards suiting 39 kinds of typical structure of qinhuangdao ' s asphalt pavement according to the actual structure , experimental section long - term observation , extensive surveys , structure theory ' s analysis and calculation
在公路等级、交通量等级、土基等级及路面材料参数研究的基础上进行路基路面设计参数敏感性分析，用以确定设计参数的变化对路基路面工作状态的影响程度，并据此给出了经济合理的路基路面设计参数范围；结合本地自然环境、筑路材料、交通状况及土质情况进行路面结构组合设计，提出了适宜于秦皇岛地区公路沥青路面的基本结构；最后根据实际路面结构、试验路的长期观测、大量调查与路面结构理论分析计算相结合，提出并推荐适合秦皇岛地区的39种沥青路面典型结构，这是本课题的主要宗旨，其研究成果将直接指导设计人员的工作，并避免随意性和盲目性，对加快秦皇岛地区公路交通事业的发展将具有十分重要的意义，对其他地区也有一定的指导意义。
