The invention discloses a foundation pit supporting method suitable for a wind power generation tower foundation platform and an on-site structure of the foundation pit supporting method, relates to the field of foundation pit supporting and aims to adapt to foundation pit supporting under the geological condition of high-sensitivity silt soil, the stability of a foundation pit is good, the bearing capacity of a soil body is high, and the pressure of the end of a pile foundation is reduced. The foundation pit supporting method comprises the following steps that S1, multiple circles of engineering pile sets are constructed, a plurality of engineering piles are evenly arranged on each circle of engineering pile set in the circumferential direction of the circle, and the parts, higher than the bottom elevation of a foundation pit, of the engineering piles are used for being connected with a foundation platform; s2, multiple circles of jet grouting pile sets are constructed, a plurality of jet grouting piles are
