Abstract: The steel reinforcement cages with hexahedral shape are widely applied to river closure. Through tests and engineering example verifications focusing on weight, shape and bottom protection, the related formulas are fitted for the first time to compute the flow velocities for movement stopping and movement initiation of hexahedral steel reinforcement cages in consideration of cage shape and bed roughness. The fitted formulas are of high accuracy and practicality. In addition, tests on the stability of steel reinforcement cage with tetrahedral shape.

Key words: river closure, steel reinforcement cage with hexahedral shape, steel reinforcement cage with tetrahedral shape, stability behavior, influencing factor, computational formula
