With　a　great　number　of　applications　in　various　engineering,　the　durability　and　service　life　of　the　anchorage　structure　have　become　an　important　subject　in　the　process　of　the　development　of　anchorage　technology.　In　this　paper,　using　the　method　of　combining　indoor　experiment　with　theoretical　analysis,　the　durability　and　service　life　of　anchorage　structure　are　comprehensively　analyzed　by　using　the　grey　system　theory.　©　2016　Taylor　&　Francis　Group,　London,　UK.
