Abstract:The 6m×6m castinsitu concrete hollow floor laying tube filler is tested. The development rules of cracks，failure model, loaddeformation relationship and ultimate bearing capacity of the castinsitu concrete hollow floor bearing vertical uniform load are gained. The results show that the castinsitu concrete hollow floor laying tube filler in one way has evident two way character,and it can be provided with good deformation behavior and high bearing capacity.
