摘要
目前对于锚杆挡土墙联合支护形式的整体稳定性分析,尚无统一的计算模式,应用Plaxis有限元软件,对重力式挡墙和锚杆的联合支护的边坡进行稳定性分析。对土体本构模型的选择、支护结构材料模型的选择、参数取值、计算方法等进行阐述,并对某一具体工程实例进行模拟计算。结果表明Plaxis有限元软件可以对锚杆挡土墙联合支护形式进行模拟分析计算,为边坡联合支护中支护结构的设计提供依据。
Therer is no unified computing model for the stability analysis of combined support by anchor rod retaining wall. In this paper the author analyses the stability of combined support by＇anchor rod retaining wall by the application of the finite element software about Plaxis. In this paper, the selection of constitutive model of soil supporting structure, the selection of material models ,parameters, calculation methods are discussed ,and a specific project examples are numerically simulated. It provides a basis for the design of retaining structure.
