The invention belongs to the field of soft land foundations, and particularly relates to a machine tool foundation for being built on soft land.The machine tool foundation is built by foaming cement.The foaming cement is prepared from, by weight, 20-30 parts of modified acrylic epoxy resin, 1-3 parts of phosphoric acid, 3-10 parts of zinc powder, 3-8 parts of water, 10-13 parts of glycerol, 8-10 parts of polyvinyl alcohol, 30-60 parts of iron-ore slag and 15-30 parts of ceramic micro-spheres, wherein the modified acrylic epoxy resin is obtained through a reaction of 1,4,5,8-naphthalene tetracarboxylic acid and acrylic epoxy resin on the basis of the mole ratio being 1:1.The machine tool foundation can directly act on the soft land to be built, and the construction amount and the human cost can be decreased.
