So an in-situ method is preferred in important engineering projects. The experimental studies on large rock socketed pile's confining bearing capacity properties were carried out in the dug piles' bottom at construction zone C of Guangzhou new television station tower site. The short concrete piles were used to simulate the real piles, and the confining friction force between the short pile and the rock mass was determined. The compressive friction tests and the pulling out friction tests were conducted, and the confining friction forces between the short pile and the rock mass were used to determine confining friction parameters. The tests results show that the piles' confining friction properties are quite different under the compressive force conditions and under the tensile force conditions, and the compressive friction characteristic value is always larger than that of the pulling out friction. According to the tests analysis, a tensile partial coefficient may be defined for the pile's pulling out resistant force computation to achieve a larger safety factor in important buildings. In this new television station tower site project, the tensile partial coefficient is about γ in the range of 1.5～2.0, and the tests results provide a useful reference for important building
