The invention discloses a highway concrete precast block composite retaining wall structure and a preparation method. The highway concrete precast block composite retaining wall structure comprises an outer wall and an inner framework, wherein concrete precast blocks are built on the outer wall; and a rubble concrete layer is poured on the inner framework. The preparation method comprises the following steps: step I, flatly treating a soil body or a mountain or the original ground to form the outer wall and the inner framework; step II, pouring the rubble concrete layer on the inner framework until reaching certain initial setting strength; step III, adopting a special mould to form the concrete precast blocks; and step IV, building the concrete precast blocks on the outer wall. The highway concrete precast block composite retaining wall structure has the advantages that: the dimension standards are unified, factory-like processing is realized, quality is easy to control, transportation is convenient, and sit
