Abstract:

By comparing the relevant provisions of rock-socketed pile bearing capacity calculation in the standards and regulations of different industries and different regions, and starting with the main factors influencing the bearing capacity of rock-socketed pile, the paper analyses the similarities and differences among all kinds of specification methods, pointing out the shortcomings of the current specifications, and puts forward the author’s suggest for rock-socketed pile bearing capacity calculation .

Key words: rock-socketed pile, Code, Rock socketed depth diameter ratio, Uniaxial compressive strength, Standard value of the bearing capacity if a single pile
