High and steep slope slab staggering soil retaining type bridge abutment and construction method

The invention discloses a high and steep slope slab staggering soil retaining type abutment and a construction method, a traditional abutment arrangement mode is abandoned, a novel high and steep slope slab staggering soil retaining type abutment structure mode is adopted, and the high and steep slope slab staggering soil retaining type abutment comprises a side face retaining wall system, a front face retaining wall system, a side face foundation slab staggering system, a front face foundation slab staggering system, a slab staggering connecting system and an abutment rear bridge road connecting system. Road engineering construction is limited by high and steep slopes in complex and hard mountainous areas, for example, the road engineering construction is arranged according to a conventional bridge abutment mode, the excavation depth of a foundation or a bearing platform foundation pit is large, large-range excavation easily causes ecological damage and water and soil loss, for example, measures are taken to
