| 摘 要： | 研究在高填方路堤中铺设土工合成材料的最佳加筋位置的确定方法. 基于极限平衡理论,采用在土内加筋的方法增加剪切面上的正应力以提高土体的抗剪强度,从而改进了加筋路堤. 获得了确定最佳加筋位置的方法,并利用计算机进行滑动面搜索确定了最佳加筋方案. 通过对8种典型黄土加筋高填方路堤的稳定性分析与最佳加筋位置的应用分析,验证了此方法的可行性和筋材的加筋位置及其效果.

| Abstract: | The best reinforced scheme for laying geosynthetics on high embankment is investigated.Based on the limit equilibrium theory,a new concept is applied to improve reinforced embankment which geosynthetics can raise the shearing strength of soil by increasing the direct stress of shearing surface.The best reinforced scheme methods are deduced,and a method of ascertaining the best reinforcement scheme using computer aided search of circular failure plane is also obtained.By the stability analysis and applied best reinforced location analysis of 8 kinds of typical reinforced loess embankment,the feasibility application of methods and the effect of best reinforced location are verified. |
