【目的】为确保江河堤防溃口的稳定性,探究科学、高效且适应性强的溃口堤头裹护新技术。【方法】基于锚阵生根原理与锚索串钢网石笼阻水技术,提出一种基于动力锚的溃口堤头稳固新技术。该技术通过火箭锚与钢网石笼结合,快速构建溃口堤头的稳固结构。同时,利用FLOW-3D软件对锚索-钢网石笼一体化进行数值模拟,分析了锚索力的影响因素,研究了锚索力与悬挂石笼质量、锚索与河床倾角及溃口流速之间的关系。【结果】锚索力随悬挂石笼质量增加而增大,随锚索与河床倾角减小而增大,随溃口流速增大而增大。考虑锚索承受最大拉力情况,基本排除锚索本身断裂风险。【结论】数值分析验证了该技术锚索受力规律及应用可靠性,可为相关新技术的装备研发提供数据支撑和理论依据。
Abstract:【Objective】 To ensure the stability of river embankment breaches, this study explores a novel, scientific, efficient, and adaptable technique for breach head wrapping. 【Methods】 Based on the principle of anchor array rooting and the water-resisting technique of connecting steel mesh gabions with anchor cables, a novel technique using dynamic anchors was proposed to stabilize breach embankment head. The technique combined rocket anchors with steel mesh gabions to rapidly construct a stable structure at the breach head. Concurrently, numerical simulations of the integrated anchor cable-steel mesh gabion system were conducted using FLOW-3D software to analyze the influencing factors of anchor cable force and investigatethe relationships between anchor cable force and suspended gabion mass, the inclination angle between anchor cable and riverbed, and breach flow velocity. 【Results】 The anchor cable force increased with the suspended gabion mass, increased as the inclination angle between the anchor cable and the riverbed decreased, and increased with the breach flow velocity. Under the maximum tensile load on the anchor cables, the risk of anchor cable fracture was essentially eliminated. 【Conclusion】 Numerical analysis verifies the force pattern of the anchor cables and the application reliability of this technique, and can provide data support and a theoretical basis for the development of related equipment.
