Slope Anchoring Technology in China: State of the Art Report and its Prospect

Anchoring technology is an engineering research focus for its successful application in practice and huge economic benefits in slope stabilizing. To construct an anchorage, all steps are in the same importance and any mistake may cause an entire failure. In order to promote the combination of the applications and the theoretical studies of slope anchoring, the theoretical results, practical utilities and quality-control methods on slope anchoring in recent 20 years were discussed in this paper. The load transfer mechanism of anchorage body and the active mechanism of ground anchorages were detailed mentioned. As to practical utilities, the construction standardization, anchorage type, grouting, corrosion prevention, and other techniques were presented. When it comes to quality controlling, some discussions on anchorage field experiments, long-term monitoring, and non-destructive examination were carried out. Finally, some suggestions are proposed on open questions about theoretical study, practical utility, quality controlling.
