Enhanced high-durability foam light soil

The invention discloses enhanced foam light soil with high durability. Raw materials comprise cement, fly ash, a foam group, reinforced fibers, an accelerator, a reinforcing agent and silica fume. A foaming agent aqueous solution is prepared into foam by a physical method, then the foam is mixed and stirred with necessary components including cement, fly ash, foam groups, reinforced fibers, an accelerator, a reinforcing agent and silica fume according to a certain proportion, and the mixture is hardened by physical and chemical effects to form a light material. The foam light soil has the characteristics of light weight, adjustable density and strength, good constructability, environmental friendliness and the like, wherein the performance of the material is emphasized to replace conventional filling, so that the problems that large instruments are needed in the filling backfilling process and later settlement is caused are solved, and the effects of shortening the construction periodand reducing post-constru
