摘要
Self-balancing test has just been used in China, which is a promising new technology in the aspects of technology and economy. But its theory has to be perfected. Through the finite element method, the pile bearing capacity under the self-balancing test can be studied. It is shown that based on the finite element model the "balancing point" can be analyzed and demonstrated; the side friction of the upper segment and the resistance of the lower segment of pile can be simultaneously acted when using the self-balancing test; the size of modulus ratio E1 /E2 of soil in side pile and the soil of the bottom pile can influence the bearing capacity of pile.
