The Kretek 2 Bridge was built over the Opak River where there is an active fault. According to bore log data and embankment site analysis, there is potential for liquefaction at a depth of 0 - 3 meters. Due to space limitations, ramp of bridge must be able to stand upright. An alternative treatment that can be implemented in this condition is to reinforce the embankment at the bridge ramp with the Mechanically Stabilized Earth Wall system. Analysis of liquefaction potential using the method of Idriss and Boulanger. Analysis of the application of the planned MSE wall was carried out based on the external, internal, and global stability in dynamic conditions in the subgrade after replacing the subgrade in the detected layer of liquefaction potential. The method for calculating the lateral pressure caused by an earthquake uses the pseudostatic method. The MSE wall with soil replacement meets the requirements for external, internal, and global stability under dynamic conditions to be an alternative solution to mitigate liquefaction potential and increase soil bearing capacity and limitation area problems. Reinforcement of friction tie using granular embankment gets good results in the calculation of safety factor breaking, pull out, overturning, and sliding.

“…This configuration is referred to as an MSE wall, whereas the front sections work as a basis for support and the soil serves as a strengthening structure (as shown in Figure 1). The facing of MSE walls is commonly constructed using various thin components, including precast concrete tiles, dry cast modular boards, metal sheets and plates, welded metal mesh, bonded wire mesh panels, shotcrete, hardwood lagging and columns, and bundled sheets of geosynthetics [18]. The soil behind the facing is then compacted and supported by materials such as steel strips or bars, welded wire mats, polymer surfaces, or geotextile supports, which mechanically stabilize the entire structure [19].…”

Mechanically stabilized earth (MSE) walls are recognized for their cost-effectiveness and superior performance as earth-retaining structures. The integration of internally reinforced walls has transformed soil preservation practices, garnering significant attention from the global technical community. The construction method of MSE walls has recently gained widespread popularity, likely due to its cost efficiency and simplicity compared to traditional externally reinforced walls. This paper provides a comprehensive review of MSE walls, including their historical development, aesthetics, benefits, drawbacks, factors influencing lateral displacements and stress responses, and the concept of the MSE wall system. Key approaches for analyzing seismic soil–structure interaction (SSI) issues are emphasized, investigating the dynamic interaction between the structure and soil through various research methodologies. This study incorporates multiple publications, offering an in-depth review of the current state of dynamic SSI studies considering surrounding structures. The findings emphasize the significant sensitivity of the dynamic behavior of mechanically stabilized earth (MSE) walls to soil–structure interaction, highlighting the necessity for continuous research in this area. The paper identifies research gaps and proposes future directions to enhance MSE wall design and application, facilitating further advancements in earth-retaining structures.

“…It is essential to ensure that retaining walls are constructed with high-quality materials, appropriate foundations, and proper drainage systems. Regular inspections and maintenance can help identify any signs of deterioration or structural weaknesses, allowing for timely repairs or replacements to prevent failure [49]- [56]. The use of assessment methods, such as geotechnical evaluations and structural analysis, can provide valuable insights into the integrity of the retaining wall, identifying potential problems before they become major issues.…”

This study presents an investigation into the failure of a MSE retaining wall in Tennessee, USA. The wall was constructed to support an embankment development, but it failed catastrophically, causing damage to the road and posing a significant safety risk to the public. The investigation involved a comprehensive site visit, field data collection, laboratory testing, and numerical modeling. This investigation revealed that the failure of the retaining wall was caused by inadequate construction practices. Specifically, the wall was not constructed in accordance with design specifications, and the backfill material used was not properly compacted. The construction issues resulted in the differential settlement of the wall, which ultimately caused it to fail. Based on the findings of this study, a set of recommendations were proposed for the design and construction of future retaining walls in similar geotechnical conditions. The recommendations include the proper selection and use of backfill material, proper compaction of backfill, and adherence to design specifications. The results of this study are expected to contribute to the development of improved design standards and construction practices for MSE retaining walls in Tennessee and other regions with similar geotechnical conditions.
