| Abstract: | Based on the results of the laboratory test and field test,a theory is put forward about the rational match between drill hole and bolt's diameters.The test results illustrated that the anchor force is the biggest when 22mm threaded steel bolt without longitudinal reinforcement or 20mm threaded steel bolt with longitudinal reinforcement are used in 28mm drill hole. |
