摘要
格构梁锚索复合结构体系广泛应用于边坡支护,但其理论研究远远滞后于工程应用.本文以实际工程为背景构建数值分析模型,以传统边坡稳定性分析为基础,采用有限差分商业程序进行数值计算,用传统边坡稳定性分析方法验证数值计算的可靠性,并基于数值分析模型获得格构梁锚索支护边坡的稳定系数,优化支护参数,最后考虑格构锚梁弹性地基受力特征,进行配筋设计.可快速实现支护方案设计.工程应用表明该方案切实可行,具有一定的推广意义.
While the compound structure of RC lattice frame beam and prestressed anchor is widely used in slope support,the research lags behind the application.In this paper,a numerical analysis model is established under the background of practical engineering.Based on the traditional slope stability analysis,the reliability of numerical calculation is verified.Then,based on the numerical analysis model,the stability coefficient and optimized support parameters of the RC lattice frame beam and prestressed anchor supported slope are obtained.Finally,the reinforcement design of the RC lattice frame beam is carried out by considering the mechanical characteristics of elastic foundation of lattice frame beam.The engineering application shows that this method is suitable for many similar projects and has certain popularization significance.
