The invention relates to a geotechnical network frame, which comprises geotechnical network layers which are stacked and bundled by ropes to form a network frame body. The geotechnical network layer comprises a plurality of geotechnical strips, and adjacent geotechnical strips being bundled by ropes to form a geotechnical network layer on the same plane. The geotechnical network frame and the application thereof provided by the invention can solve the problems of poor mechanical performance and long manufacturing time after geobag connection in the prior art. The structure is stable, high bearing capacity and beneficial shock absorption effect on engineering are achieved, the bearing capacity of the foundation or the stability of a slope or a retaining wall is effectively improved, and engineering disasters such as foundation instability, landslide and the like are greatly reduced.
