The karst is one of the main bad geological problems, which determines the design of the subgrade treatment plan and the safety of the engineering construction.This paper summarizes the key technology of grouting in karst roadbed regulation, and the following factors should be considered in grouting scheme selection: grouting method, technology, material, equipment, grouting control and detection means and standard of grouting effect.Through the use of high density electrical method, transient surface wave method, core drilling method, pressure water test method and so on, study the targeted detection methods for different coverage karst types and different remediation methods.
