Abstract
There is a strong engineering practical and theoretical reference value in solving the uplift ultimate bearing capacity of oblique slope pile foundation. With the oblique slope conditions, load transfer calculation in pile-soil system and formula of ultimate bearing capacity for pile foundation are derived in this paper. We also contrast the theoretical value derived by the formula, analog values based on FLAC3D software and the field test results. On this base, we calculate the ultimate bearing capacity of oblique slope foundation by using FLAC3D software and analyze the capacity change law and influencing factors on different conditions. The study showed that: the calculation formula of ultimate bearing capacity, FLAC3D numerical value and test calculation results can be most consistent. The slopes pile foundation bearing capacity is little influenced by the slope, provisional slope distance, but relatively large impacted by pile length. Within a certain range, we can improve its bearing capacity by increasing the length of the pile.
