In strong salty soil area headchute cuts off formula ballastless track cutting foundation bed structure to in the solution the technological problem that strong salty soil area high -speed railway ballastless track cutting design faces satisfies high -speed railway ballastless track and warp control, life requirement. It includes: the type of falling L inoxidizing coating sets up on the foundation bed excavates the both sides side slope, the salt french drain is arranged in vertical infiltration, sets up in the foundation bed both sides type of falling L inoxidizing coating toe department, the basement cuts off the layer, sets up to arrange salt french drain top in foundation bed bottom surface and vertical infiltration, the basement cuts off layer top and lays in proper order from supreme down that structural layer under the bottom layer of the subgrade bed, the last structural layer of bottom layer of the subgrade bed, foundation bed cut off layer, the foundation bed top layer, theescape canal sets up structural layer both sides on bottom layer of the subgrade bed.
