Abstract：a multi-functional anchor method，that is called self drilling-grouting anchor，is presented. The action mechanism of this method is analysed to grouting results for soil-reinforcement and preloading of anchor. With unique features of the presented method，it can be used to improve the soil strength，and increase the stability of slope during excavation.
