摘　　要：抛投四面六边透水框架群是一种新的护堤固岸技术。在进行了架空率、杆件长宽比对框架群减速促淤效果比较的室内试验后,得出了与最佳减速率对应的架空率和杆件长宽比的取值范围。The technology of casting tetrahedron-like penetrating frames for protecting levee and fixing revetment is a newly developed technology. After the laboratory tests of the effects of the overhead ratio and the pole's length-width ratio on deceleration and accretion promotion, the value scope of the overhead ratio and pole's length-width ratio which have the optimum deceleration efficiency are presented.
