Abstract: This article analyzes the disease problems of the hidden drainage facilities of mountain highways, and proposes prevention and treatment measures. According to the actual survey results of a mountainous road, the problem of mountain road drainage and the damage of the drainage problem on the roadbed are analyzed, and the disease forms of the hidden drainage engineering of the mountain highway are summarized, and the causes of the hidden drainage engineering diseases are analyzed at the same time. On this basis, targeted prevention suggestions and measures are put forward. At the same time, several commonly used engineering geophysical prospecting methods are compared, and a combination of geophysical prospecting and drilling is proposed, which can have a good detection effect on diseases in the maintenance project.
