“…This result was reasonable and similar to previous research results [36,37]. It indicated that the experimental results from this full-scale The distribution of the tensile force in the reinforcement layers from this study was similar to the reports of Schlosser [33], Wichter et al [34], Murray and Farrar [7], Chau et al [35], and Chau and Nguyen [28] as well as design procedures [12-14]. However, the steel ribs included in the reinforcement grids caused a step in the tensile force distribution curve in front of and behind the ribs.…”

Mechanically stabilized earth (MSE) walls have been widely applied in construction to maintain the stability of high embankments. In Vietnam, imported reinforcement materials are expensive; thus, finding locally available materials for MSE walls is beneficial. This study examines the behavior of an MSE wall using local reinforcement materials in Danang, Vietnam. The MSE was reinforced by self-fabricated galvanized steel grids using CB300V steel with 3 cm ribs. The backfill soil was sandy clay soil from the local area with a low cohesion. A full-scale model with full instrumentation was installed to investigate the distribution of tensile forces along the reinforcement layers. The highest load that caused the wall to collapse due to internal instability (reinforcement rupture) was 302 kN/m2, which is 15 times greater than the design load of 20 kN/m2. The failure surface within the reinforced soil had a parabolic sliding shape that was similar to the theoretical studies. At the failure load level, the maximum lateral displacement at the top of the wall facing was small (3.9 mm), significantly lower than the allowable displacement for a retaining wall. Furthermore, a numerical model using FLAC software 7.0 was applied to simulate the performance of the MSE wall. The modeling results were in good agreement with the physical model. Thus, self-fabricated galvanized steel grids could confidently be used in combination with the local backfill soil for MSE walls.

“…Currently, most types of locally available backfill material in Danang City, Vietnam, are cohesive soil and they do not meet the requirements of the mechanical, physical, and chemical properties of reinforced backfill materials according to the standards [26,28].…”

Hiện nay, khi xây dựng tường chắn đất có cốt ở Việt Nam thì đều phải sử dụng các loại cốt nhập từ các hãng của nước ngoài. Bài báo đề xuất sử dụng cốt thép thương mại mạ kẽm dùng cho tường chắn đất có cốt. Nghiên cứu chỉ ra rằng ổn định nội bộ của tường chắn đất có cốt phụ thuộc nhiều vào tương tác đất-cốt và môi trường. Tương tác đất-cốt phụ thuộc chủ yếu vào tính chất cơ-lý (độ ẩm, thành phần hạt) và hình dạng của cốt, tuổi thọ của cốt phụ thuộc chủ yếu vào hóa tính (trở kháng, pH, Cl-, SO42-) của vật liệu đắp và môi trường. Các yếu tố cơ-lý-hóa chính của vật liệu đắp của 75 mỏ thu thập tại Miền Trung và cốt được thí nghiệm theo các tiêu chuẩn hiện hành để lựa chọn ra mỏ vật liệu đắp phù hợp cho tường chắn đất sử dụng cốt thép mạ kẽm. Mô hình thực nghiệm tỉ lệ 1/1 mô phỏng ứng xử của tường và từ đó dự báo thời gian phục vụ của tường chắn dưới tác động xâm thực của môi trường.

The construction of earth walls can be a significant response to prevent the next landslides from reaching the road and avoid accidents. Therefore, a material of the same slope was used and reinforced with mixtures of lime and cement, with this same reinforced material a mechanically stabilized hypothetical earth wall (MSE) was developed. An analysis of the original slope was developed to check if there was a possible failure through its safety factor. Then, a hypothetical wall was developed with a floor reinforced with mixtures, in order to assess its overall safety factor and its maximum landslides. According to the results, in principle it was determined that the dosage M-3 / C-4-4 improves in a range of 30% to 37% the friction angle. In addition, it was found that a reinforced wall, that is to say with Lime and cement additions, presents a better behaviour. In its effect, its displacements are about 8 mm and have a global factor of 1.23.
