The soil reinforcement by geosynthetics has been extensively applied in covers and liners of landfills. The stability of this structure is especially dependent on the effectiveness of the anchorages holding the geosynthetic sheets. The simple run-out and L-shaped anchorages are the two most commonly used approaches. For increasing the available knowledge of the anchorage system behavior, experimental studies have been conducted. This paper shows the results of the experimental analysis that are based on the results of large-scale pullout apparatus on geogrid embedded in simple run-out and L-shaped anchorage in two modes (fixed length and fixed space). The influence of different geometric parameters of the trench on the behavior of the geogrid is also examined. Based on the results, the values of pullout force were approximately 69% and 196% higher in the case of the fixed length mode and the fixed space mode, in the respective order, compared to the simple run-out anchorage. In the L-shaped anchorage, it is observed that for the initial length (L) constant, the mode is optimized with a small value of the geogrid rear heel length (B) and a greater value of the depth of the buried geogrid (D) when D+B is constant.

土工合成材料的土壤加固已广泛应用于垃圾填埋场的覆盖物和衬里。这种结构的稳定性尤其取决于固定土工合成材料板的锚固的有效性。简单的跳动和 L 形锚固是两种最常用的方法。为了增加对锚固系统行为的可用知识，已经进行了实验研究。本文展示了基于大型拉拔装置在土工格栅上嵌入简单跳动和 L 形锚固两种模式（固定长度和固定空间）的结果的实验​​分析结果。还检查了沟槽的不同几何参数对土工格栅性能的影响。根据结果​​，与简单的跳动锚固相比，固定长度模式和固定空间模式的拉拔力值分别高出约 69% 和 196%。在L形锚固中，观察到对于初始长度（L）常数，采用较小的土工格栅后跟长度（B）和较大的埋地土工格栅深度（D）值来优化模式) 当 D+B 是常数时。
