Brief introduction to worldwide test types of anchorage

There are three test types of ground anchor such as basic test, creep test and acceptance test in China, and performance test, proof test and extended creep test in US, and investigation test, suitability test and acceptance test in EU. In addition, there are some tests for some determinate aspects of anchor performance in US and EU such as lift-off test, oscillating load test, testing of corrosion protection, test for cyclic work load, etc. The demands for anchor tests in US code is relatively simpler while more strict and precise in EU code. The meaning and function of basic tests on anchor attract no enough attention in China. It should be more zetetic but not proof for testing and understanding the anchor performances more adequately.
