The invention discloses a method for calculating the pressure of soil between double-row piles of a foundation pit on the pile side based on natural source surface waves, which comprises the following steps of: acquiring natural source surface wave data, and processing the data to obtain the thickness of a stratum above the bottom surface of the foundation pit, the number of stratums and the surface wave speed; further determining the influence coefficient of the double-row piles, the influence factor of each soil layer above the bottom surface of the foundation pit, the change value of the horizontal distance between the double-row piles, the influence coefficient of the depth of the foundation pit, the equivalent internal friction angle of the soil layer above the bottom surface of the foundation pit and the initial stress influence coefficient, and directly calculating the pressure of the soil between the double-row piles of the foundation pit to the pile side by utilizing a formula.
