Prefabricated and assembled retaining wall systems are gradually becoming the choice for slope stabilisation and earth-retaining structures. However, current prefabricated retaining wall systems are often difficult to apply in complex and variable construction sites due to issues such as inconsistent production dimensions and transportation difficulties. This paper presents a novel prefabricated retaining wall system and reports centrifuge model tests performed to analyse its overall performance. The influence of different infill materials on the performance of the prefabricated retaining wall system was studied. The research findings reveal that the retaining wall system provides significant slope stabilisation effects and can withstand up to four times the stress level of a natural slope. Moreover, the stability of the retaining wall system is more than twice better when infilled with frictional soil compared with that when clay infill is used. Due to its unique structure, it can not only reduce material consumption and carbon dioxide emissions by around 63.94% but also allow planting of green plants in the gaps of components, thereby providing a more sustainable alternative to conventional concrete gravity wall systems.

基于离心机试验的预制挡土墙系统性能评估

预制和组装式挡土墙系统正逐渐成为边坡稳定和挡土结构的选择。然而，目前的预制挡土墙系统往往因生产尺寸不一致、运输困难等问题而难以应用于复杂多变的施工现场。本文提出了一种新型预制挡土墙系统，并报告了为分析其整体性能而进行的离心机模型测试。研究了不同填充材料对预制挡土墙系统性能的影响。研究结果表明，挡土墙系统具有显着的边坡稳定效果，可承受高达天然边坡四倍的应力水平。此外，与使用粘土填充相比，填充摩擦土时挡土墙系统的稳定性提高了一倍以上。由于其独特的结构，它不仅可以减少约63.94%的材料消耗和二氧化碳排放，而且可以在构件的缝隙中种植绿色植物，从而为传统混凝土重力墙系统提供更可持续的替代方案。
