Abstract: In this paper, a point that the recommended values of geotechnical parameters should be considered in the entire process of the engineering characteristics is proposed. As inthe pile supported foundations, the influencing factors of geotechnical parameters test value arebrieflyevaluated. Further, the difference reliability requirements on the geotechnical parameters for the pile supported foundation are discussed in the paper. Based on the above evaluations, the method of providing reliable and reasonable recommendation values of geotechnical parameters for the pile foundation in accordance with the statistical data of physical and mechanical test indexes is also proposed.

Key words: Pile Foundation, Geotechnical Parameters, Reliability, In-situ Testing, Physical and Mechanical Test
