目前根据我国生产建设的需要,对于苏联伊万诺夫教授所创立的柔性路面的理论和设计方法,有进一步究研的必要。我们究研这个问题,不仅是理论方面,更重要的还有如何结合我国具体情况的一面。但是:必须指出,伊氏的理论和概念,对于柔性路面来讲,仍然是现在世界上的最先进方法。应当肯定这个理论还是正确的,没有什么根据可以值得怀疑。不过,这个理论,仍限于单层路面分析的范畴。对于多层路面的分析,还应当进一步去发展。附属于这个理论的一些参数,在目前应用方法上,无疑的是过于一般化而且个个孤立,彼此没有相互制约的关系,也没有因地制宜的变化作用。因此,进行究研这个问题,须抓住它的关键,解决它的中心问题。这些中心问题应当是:(1)多层路面的理论分析(2)土基形变模量问题(3)路面材料形变问题(4)土壤水温情况问题(5)车辆换算及形变累积问题(6)相对形变问题。研究这六个问题,主要的原则是由单层路面的理论概念确定多层路面的理论基础。对于各种参数,重要的原则是建立它们彼此制约的关系和如何根据具体情况来确定它们的数值。由路面设计总的方面来讲,应当建立极限设计的原则,尽量利用路面材料结构的能力,达到节省经济而又合用的目标。
At present, according to the needs of China’s production and construction, the theory and design method of the flexible pavement established by Professor Ivanov of the Soviet Union are necessary for further research. We study this issue not only in theory, but more importantly, in how to combine the specific circumstances of our country. However: It must be pointed out that the theory and concept of Iraqi is still the most advanced method in the world today for flexible pavement. It should be affirmed that this theory is still correct and that there is no basis for doubt on it. However, this theory is still limited to the category of single-layer pavement analysis. For multi-pavement analysis, but also to further development. Some of the parameters attached to this theory are undoubtedly overly general and isolated in the current application methods. They do not have any mutually restrictive relationship with each other nor have they been changed according to local conditions. Therefore, to study this issue, we must seize the key to solve its central issue. These central issues should be: (1) theoretical analysis of multi-layer pavement (2) deformation modulus of soil foundation (3) deformation of pavement materials (4) soil water temperature problems (5) vehicle conversion and deformation accumulation problems Relative deformation problem. To study these six issues, the main principle is that the theory of single-layer pavement theory to determine the theoretical basis of multi-layer pavement. For all kinds of parameters, it is important to establish the relationship between them and how to determine their values on a case-by-case basis. From the overall aspect of pavement design, the principle of limit design should be established to make full use of the ability of pavement material structure to achieve the goal of economizing and combining economy.
