SNS 柔性主动防护网承载能力及防护设计研究

摘要

The SNS flexible active protection network is widely applied in slope works because of its superior protection property.As its mate-rials all are flexible as well as the topography and landform of slopes covered by the active protection network are complicated relatively, it is normally designed according to the tensile strength of the steel cable.So, it is difficult to analyze the action forces of the active network.In theory, there is not practical method for calculation.Based on the engineering practice, in the paper, the generalization analyzing method is applied to calculate the bearing capacity and protection ability of the steel cables of the SNS flexible active protection network ( in rhombus ), providing application of the SNS flexible active protection network in projects with theoretic basis.%SNS柔性主动防护网以其卓越的防护性能广泛应用于边坡工程。由于其材料均为柔性材料，且主动防护网覆盖的边坡地形、地貌相对复杂，工程设计中一般采取保守的钢丝绳抗拉强度进行设计，对主动防护网的受力分析比较困难，从理论角度目前仍然没有较为成熟的计算方法；文章以实际工程为依托，运用概化分析方法计算SNS柔性主动防护网（菱形网）钢丝绳的承载能力及防护能力，为SNS柔性主动防护网在工程运用提供理论依据。
