The tetrahedron-like penetrating frame dam,the cross section of which is trapezoid,is built by piling the tetrahedron-like penetrating frame.Through the dropping test of the tetrahedron-like penetrating frame dam on land and in flume,we study the number of frames in unit volume and the porosity and analyze the construction technology and inspection standard of the frame dam.The study provides not only a quality control range of frame dam construction,but also serves as a basis and reference on the construction and acceptance of tetrahedron-like penetrating frame dam in the inland river.
