摘要
以广州飞碟训练中心人工高边坡工程为背景,讨论了人工高边坡设计中的若干关键技术问题,介绍了边坡设计方案。基于相同物理模型和边界条件,先后运用不同极限平衡理论分析该高边坡稳定性,分析了不同极限平衡法计算结果的差异和原因,以及极限平衡法在边坡计算中的限制。运用有限元强度折减法进行相同条件下的计算,并对不考虑锚索加固和考虑锚索加固的边坡计算结果进行比较,分析边坡变形特征和破坏机制,指出有限元折减强度法的优势。
Based on the high slope engineering of Guangzhou Skeet & Trapshooting Training Centre,some of the key technique problems of the high slope designing are discussed;and the reinforced design of the high slope is introduced.It is assumed on the same physical model and boundary conditions,the different limit equilibrium methods(LEM) are adopted to analyze the stability of the high slope;and the different results involves different methods are analyzed and the reasons are discussed.Lastly,the finite element method(FEM) based on shear strength reduction technique are adopted;and the unreinforced slope and the reinforced slope are concerned and calculated.It is pointed out that the deformation characteristics and failure mechanism calculated by FEM are different from that’s from LEM because of its principles and assumption.
