The invention discloses a method for eliminating loess foundation collapsibility through microwave heating. The method includes the steps that firstly, a processing area is determined, and according to collapsible loess area building standards, the plane processing range and the processing thickness of a collapsible loess foundation are determined; secondly, drilling is carried out, soil around drilled holes is heated through microwave irradiation, an engineering geological drilling rig is adopted for drilling, the depth of the drilled holes is the same as the processing thickness of the collapsible loess foundation, and the drilled holes are distributed in a quincunx shape, a rectangular shape or a cuboid shape; in the drilling process, after each drilled hole is formed, the soil around the drilled hole is heated through microwave irradiation in a segmented mode from bottom to top by means of a microwave heating device; thirdly, the drilled holes are filled with cohesive soil, and layered compacting is carried out. The method is simple in step and convenient to implement, can effectively eliminate collapsibility of the collapsible loess foundation, and is wide in application range, free of pollution, easy to control in site, high in practicality, good in use effect and convenient to use and popularize.
