中文摘要：

关于水平加强和垂直加强的工作机制基于讨论分别地，二方向的增强的合成基础的工作机制被学习。提高的效果水平，垂直增强的合成基础上的加强被分析。为如此的二方向的增强的工作系统的一个简化计算方法被介绍。一个模型实验被执行验证建议方法。在实验， geocell 加强作为水平加强工作了，当时石子堆积合成基础作为垂直加强工作了。结果证明“计算曲线接近测量那条。geosynthetic 加强的安装能在正常基础解决增加合成基础的适用的电容将近 68% ，它建议由 geosynthetic 加强的提高的效果应该在当前的设计 / 分析方法被考虑。

英文摘要：

Based on the discussion about working mechanism of horizontal reinforcement and that of vertical reinforcement, respectively, the working mechanism of two-direction reinforced composite foundation was studied. The enhancing effect of horizontal reinforcement on vertical reinforced Composite foundation was analyzed. A simplified calculation method for such two-direction reinforced working system was presented. A model experiment was carried out to validate the proposed method. In the experiment, geocell reinforcement worked as the horizontal reinforcement, while gravel pile composite foundation worked as the vertical reinforcement. The results show that the calculated curve is close to the measured one. The installation of geosynthetic reinforcement can increase the bearing capacity of composite foundation by nearly 68% at normal foundation settlement, which suggests that the enhancing effect by geosynthetic reinforcement should be taken into account in current design/analysis methods.
