School of Civil Engineering and Transportat ion, South China Universit y of T echnology, Guangzhou 510641, Guangdong, China; 2. Guangzhou Institute of Building Science, Guangzhou 510440, Guangdong, China) Abstr act: The calculation theories of pile were summarized. The calculation methods and procedures of load2settlement whole process were introduced. Sever al main calculation parameters and their influences on the r esults were discussed. The load2settlement whole process of two testing piles were simulated by using ADINA software, and the changing rules of pile skin friction for different soils were obtained. The values of side soil resistance of differ ent soil sections were calculated and compar ed with testing values. The super iority and shortage of ADINA calculation system were analyzed and the way for improving ADINA calculation was put forward. The results show that the calculated results agree well with the measured results for ADINA, and the optimizing design is made for pile foundation.
