Abstract
When m value is above 21, If the horizontal load has not reached the design value of the theoretical ultimate bearing capacity, the foundation pile will first appear bending failure. That is to say, when m value is greater than 21, the horizontal bearing capacity of pile group bearing platform foundation begins to depend on the bending strength of pile itself. The ultimate horizontal bearing capacity of pile group bearing platform foundation in actual engineering has been difficult to reach the ideal design value。 When the value of M is less than 21, the actual horizontal ultimate bearing capacity is consistent with the theoretical calculation, when the m value is greater than 21, the actual horizontal ultimate bearing capacity can be calculated according to the simplified formula proposed in this paper.
