弹性层状体系理论在土木工程中得到了广泛的应用。但是,长期以来对这个理论与实际的符合程度,总是有一些怀疑。为了检验这个理论的实用性和可靠程度,国内外都曾进行过一些实验验证工作。本文介绍我们从1978到1983年这段时间对这个课题所开展的工作,内容主要包括路面层状体系模型试验和足尺试验的结构、材料参数和应力、应变测量的概况;各项试验资料的整理结果及其与理论值的比较;层状体系理论与实际的偏离和如何修正的讨论。此外,对今后这个课题应研究的问题提出一些看法。
The theory of elastic layered system has been widely used in civil engineering. However, there has always been some doubts about the degree of conformity between this theory and practice. In order to test the practicability and reliability of this theory, some experimental verification work has been conducted at home and abroad. This article describes the work we conducted on this topic from 1978 to 1983. The content mainly includes the structure and material parameters of the pavement layered system model test and full-scale tests, and the overview of stress and strain measurements; The collation results and their comparison with theoretical values; discussion of the deviation from the theory of the layered system and the actual and how to correct it. In addition, some views should be given on the issues that should be studied in the future.
