捅要：公路路面裂缝是路面本身或路基变形的前期预兆，研究路面裂缝发生发展的原因，可以有效制定治
理方案，从而根治路面恶化的趋势。本文首先简要介绍了高频地质雷达的检测方法原理及其在高速公路的维
护治理方面的许多显著优点：无损坏、连续图像和高效准确。然后重点阐述了地质雷达在宜黄高速公路路面
裂缝检测中的应用，作者对所获取的雷达资料作了分析解释，并对公路路基变形程度提出四种划分标准，为今
后公路的保养维护提供了科学依据。

Abstract：A highway surface crack is a warning sign of highway surface or roadbed deteriora—
ting．We could make an effective plan against the highway surface deteriorating through
studying the GPR images of highway surface crack．This paper briefly introduces the basic
principle of GPR and some advantages of highway maintenance，such as nondestructive，con—
tinuous images，high resolution factor and etc．Next，the author presents an application of
GPR of Yichang—Huangshi highway crack inspection in Hubei province．He analyses the
GPR data，and then he presents four models about roadbed deteriorating degree．These mod—
els provide scientific basis for the highway maintenance in the future．
Key words：GPR；highway surface crack；nondestructive highway inspection
