Abstract
An underreamed ground anchor technique is developed for high anchorage force demand based on shaft anchors worldwide. Engineers and scholars invented various types of underreamed ground anchors, such as those based on jet grouting, mechanical reaming, and blasting. To guarantee the quality of anchorage section and reduce cost, a new type of cylindrical underreamed ground anchor with geotextile bag was developed and applied throughout China. Through 33 Q-s curves in the field tests of underreamed anchor with geotextile bag, a power function model was established for describing the relationship between the load and displacement of a cylindrical underreamed anchor. Finally, the high precision of the function model was verified.
