摘　　要：为了研究四面体块石串在河道截流中的应用规律,以模型试验的方法对不同抛投方式下块石串的稳定以及块石串在明渠中的稳定流速进行了研究,得出了不同抛投方式对块石串稳定的影响规律以及块石串体在明渠中的稳定流速计算公式。To explore the application law of the tetrahedron block rock strings in river closure operation,stability of the strings dumped in different means and the stable velocity in open channel with the strings are studied by means of model tests,the influence law of the different dumping means to the string stability and formula for calculation of the stable velocity in the open channel with the strings are derived.
