ed under the pile Based on the available tip and connected with devices. Then, during the loading test, bolts and causes the pull-out capacity to anchoring technology in geotechnical engineering, bolts are construct the reaction beam over the pile top through the developed load transfer the needed by the jacks is transferred from the reaction beam to the exert. Consequently, bolts under the pile tip supplies the required by the reacting load. Result of engineering application shows that, the developed new selfanchorage method in testing the vertical bearing capacity of pile shaft have quite a few advantages over the traditional loading test methods such as lower test cost, shorter test cycle and reliable test result. So, the proposed method in this pa per deserves in-depth theoretical research and has potential value of popularized application.
