Abstract: JGJ1202012 Edition updates the anchor rod test requirements of ground anchors and the soil nail test requirements are also included. There are differences existed in both versions of the requirements: in the new code, the ultimate test load in the acceptance test is determined by the safety requirement of the deep excavation, whereas, the old version did not have this. Further, the acceptance test location should be randomly selected but no requirements on the acceptance of the sample pool. This paper discusses the differences between old and new codes.
