The use of retaining walls for basements in buildings generally uses the retaining wall that utilizes the weight of the wall itself as reinforcement because the reinforcement is carried out only on the soil’s surface. Using steel in soil nailing construction that is too large can result in the availability of steel running out, considering that steel is a non-renewable material. The soil nailing method in this paper uses bamboo as nails. The method used in this paper is the analytical method. Data bamboo material from the tests carried out in the Laboratory Building Materials Universitas Sebelas Maret Surakarta. While material data soil obtained from tests carried out at the Soil Mechanics Laboratory Sebelas Maret University, Surakarta. The analytical model is a basement excavation 10 m deep and 20 m wide. Finite element analysis calculations using the Plaxis 8.2 program on retaining walls. The analysis stages at each excavation depth of 2 m. The model obtained that the safety factor value is 4.271; this value is greater than the required safety factor value, namely FS 2, which indicates that soil stability achieve. The analysis results also obtained the achievement of soil stability at each stage of the research. There was no collapse of the bamboo during the analysis stage. The discussion results found that bamboo substitutes steel in soil nailing reinforcement as a retaining wall in basement construction.

Field observations and Retaining Wall Failure assessment revealed both vertical settlement and lateral movement of the asphalt pavement and concrete curbs within the reinforced backfill zone of the retaining wall. Lateral and vertical ground movement near the wall has impacted the surface drainage system in the driveway area. Surface water runoff has been directed toward the wall instead of flowing into designated catch basins. The failure of the retaining wall seems to have occurred due to a connection failure at the facing panels, where the anchorage system pulled out of or sheared off the panels. This failure may have been caused by backfill settlement and the added hydrostatic pressure imposed on the wall from the migration of surface water runoff into the backfill. Our examination also revealed anchor system failures both at the wall panel connection locations as well as within the concrete deadmen anchors, where rebars appeared to have pulled out from the concrete anchor block. Additionally, we observed the absence of any drainage system in the retaining wall such as weep holes, perforated drainage pipes, or other similar features. Lateral earth pressures acting on the wall system may increase, not only due to the added weight of the backfill material but also due to the likelihood of hydrostatic pressures imposed on the wall.Furthermore, backfill material used for wall constructed appears to be non-uniform and poor quality

“…The retaining wall was constructed using poor-quality materials, and the construction techniques used were not in accordance with the design specifications. In another study, Kong et al (2021) [6] illustrated that inadequate design was the primary cause of retaining wall failure in their case study. The study proposed a remediation plan that involved reconstructing the retaining wall with improved design and construction techniques.…”

This study presents an investigation into the failure of a Mechanically Stabilized Earth (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. Our 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 our findings, we propose a set of recommendations 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.
