    ANALYSIS ON DESIGN METHODS OF EMBANKMENT SLOPE REINFORCED BY GEOGRIDS

    • 摘要: 简单介绍了《公路土工合成材料应用技术规范》(JTJ/T 019-98)中关于路堤边坡的等间距或分区等间距加筋设计方案,然后编写了程序,计算边坡在分层填筑时的安全性能,通过反复迭代计算可得出满足安全系数要求的最佳土工格栅铺设间距。最后对工程实例采用该程序进行了计算,结果表明土工格栅的最佳铺设间距不是等间距,而应尽量采用"顶疏底密"的布置方式。

       

      Abstract: The paper briefly introduces the equal interval or subzoning equal interval reinforcement design project with regard to the embankment slope in "the applied technical specification of the geotechnical composition materials for highway(JTJ/T019-98)". Then programs are written to calculate the slope safety during reclamation in layer, and the optimal laying interval of geogrid meeting safety modulus requirement is obtained through iterative computation. At last, the program is used to calculate an engineering example, and the result indicates that the best geogrid laying interval is not the equal one but the method of "sparse in top, dense in bottom", which should be utilized more later.
