This invention discloses a method for interface-controlled seepage backfilling in power transmission and transformation disturbance zones, relating to the fields of soil engineering and soil and water conservation. Addressing the problem of discontinuous interface infiltration caused by differences in particle composition and compaction between upper and lower soil layers in power transmission and transformation disturbance zones, this invention first measures the particle composition and dry unit weight of the upper root zone backfill layer and the lower support layer to construct an interface abrupt change index, thereby determining whether a transition coordination layer should be set and the number of transition sub-layers. Then, a multi-layer transition structure is constructed using a combination of particle composition gradient interpolation and incremental compaction control value design. After backfilling, the method is checked and adjusted based on the arrival time and crossing time of the wetting front, as well as changes in water content on both sides. This method helps to improve the uncoordinated phenomenon of interlayer water migration, weaken local rapid channels or stagnation trends, and improve the stability of the backfill structure in the disturbance zone.
