Based on the shear strength of the pile-soil interface of different materials and the shear performance of the soil around the pile, a calculation equation for the standard value of the ultimate lateral friction resistance of concrete piles in different homogeneous soil materials was derived and applied to the equation for calculating the ultimate bearing capacity of foundation pile and the axial force of pile.
For example, Zhu [10] measured the internal friction angles of two kinds of sand gravel soil materials, D20 and D60, respectively, as 40.1° and 43.6°using a large one-way compression meter and an earth pressure box.
