摘要

结合H-V立体土工膜（Horizontal-Vertical three-dimensional geomembrane）及传统水平土工膜衬垫与土相互作用的力学模型试验，利用基于离散元理论的颗粒流软件（Particle Flow Code， PFC），从细观角度系统研究不同几何特征的土工膜与土之间的相互作用机理。分别从已完成土工膜复合衬垫模型试验所得的宏观力学特征、不同几何特征的土工膜衬垫与土颗粒之间的位移变化规律、土颗粒与膜之间的接触力分布、膜上的应力分布及整体衬垫系统中竖向应力的分布等方面进行对比分析。结果表明：与传统水平土工膜相比，H-V立体土工膜除了具有传统水平土工膜与土之间的摩擦作用外，还有竖向膜部分对土颗粒附加的侧摩阻力和咬合力作用；竖向膜不仅可以约束土颗粒的位移和力链从受荷中心向加载板两侧方向的传递，而且能使H-V立体土工膜与土形成良好的约束挤密区，一方面延缓了H-V立体土工膜衬垫内部形成连续滑移面，另一方面更有效地均化了整体衬垫中的应力分布，使得相同上覆荷载下H-V立体土工膜衬垫的整体沉降和不均匀沉降更小。

Abstract

The mesoscale mechanism of the interface behavior of different geomembranes was analyzed systematically combining with the mechanical model test of the Horizontal-Vertical (H-V) three-dimensional (3D) and traditional horizontal geomembrane by using the Particle Flow Code (PFC) based on the discrete element theory. The mesoscale characteristics such as the displacement variation， contact force distribution between the different kinds of geomembrane liners and soil particles

the stress distribution on the geomembrane

and the vertical stress distribution in the liner system were analyzed by comparing with the macroscopic mechanical characteristics obtained from the model test. The results show that the horizontal-vertical three-dimensional geomembrane provided similar friction as the traditional horizontal geomembrane. The vertical membrane of the H-V 3D geomembrane provided additional side friction and confine force. The vertical element not only confined the displacement and contact force of the partial transferring from the center to the two sides of the footing

but also provided the squeezed region between the H-V geomembrane and soil. This delayed the happening of the continuous slip surface and homogeneously distributed the stress in the H-V geomembrane lines. Therefore

the overall and uneven settlement of the H-V 3D geomembrane liner are smaller than the traditional under the same overburden load.
