The application discloses a method for dividing the end resistance and side friction of a pile foundation in a piling process based on piling records, and the method comprises the following steps: obtaining a curve of the hammering number changing with the depth in the piling process according to the field piling records; obtaining a curve of the relationship between the hammering number and the soil resistance; obtaining a curve of the soil resistance changing with the depth in the piling process by using the two curves; determining the upper and lower envelope lines of the curve of the soil resistance changing with the depth; drawing a straight line through the (0, 0) point and the lowest point of the lower envelope line; obtaining the curve of the soil resistance changing with the depth after eliminating the linear part by subtracting the straight line part from the curve of the soil resistance changing with the depth, and determining the new lower envelope line; fitting the side friction in the piling process by drawing a straight line through the original point, the lowest point and the final point of the new lower envelope line; and obtaining the end resistance of the pile foundation in the piling process by subtracting the side friction from the curve of the soil resistance changing with the depth. The end resistance and the side friction of the pile foundation can be conveniently obtained, and the calculation precision of the pile foundation drivability analysis is improved.
