Abstract
Based on the test results of the bolt axial strain in three types of high, medium, and low strength respectively, the shear stresses of the internal anchorage section are studied. Then a method for calculating the effective length and ultimate bearing capacity of stretched bolts is established. The bolt effective anchorage length is calculated in different strength media, and several factors affecting the bolt effective anchorage length are analyzed. The results provide some insights into the effective anchorage length of anchorage structures and an applicable method for design and anchor engineering calculation.
