The role of wall facing is crucial in the design of MSE walls. This study employed two centrifuge model tests specifically designed to analyze walls with two distinct facing types: full-height panel facing and modular block facing. Additionally, surcharge loads were applied to these MSE walls to simulate real-world conditions. The findings from these tests revealed that MSE walls with full-height panel facing exhibited superior performance under the combined effects of self-weight and surcharge loads. The measured maximum horizontal displacements in walls with full-height panel facing and modular block facing were about 55% and 85% of those predicted from current design guidelines at EOS3, respectively. The influence of the surcharge loads on the reinforcement loads was found to be substantial for both wall types, especially for the case of model wall with modular block facing, where the reinforcement loads in the upper half of the wall increased by about 30% from EOS2 to EOS3. The insights garnered from this study contribute to a deeper and more nuanced understanding of the impact of facing types on the practical construction and design of MSE walls, offering valuable guidance for future engineering applications.

不同饰面类型MSE墙体性能的离心模型试验


墙面的作用在 MSE 墙的设计中至关重要。本研究采用了两种离心机模型测试，专门设计用于分析具有两种不同饰面类型的墙壁：全高面板饰面和模块化块饰面。此外，附加载荷被施加到这些 MSE 墙上以模拟真实条件。这些测试结果表明，具有全高面板饰面的 MSE 墙在自重和附加载荷的综合作用下表现出优越的性能。测得的全高面板饰面和模块化块饰面墙壁的最大水平位移分别约为 EOS3 当前设计指南预测值的 55% 和 85%。发现附加荷载对加固荷载的影响对于两种墙类型来说都很重要，特别是对于带有模块块饰面的模型墙的情况，其中墙上半部分的加固荷载比 EOS2 增加了约 30%到EOS3。从这项研究中获得的见解有助于更深入、更细致地了解饰面类型对 MSE 墙的实际施工和设计的影响，为未来的工程应用提供宝贵的指导。
