A Study on Settlement Behavior Using D-Box Method: a Case Study in Vietnam

It is noted that the settlement estimation using the D-box method (soil bag system) with a high thickness of the filling layer would have a high potential of risk, especially in the time-dependent calculation. Based on the requirements of solutions for the settlement problem of the ground-treated system in the Asia-Vietnam fertilizer factory (AVF factory), this research focuses on the settlement behavior of soil after 1 year of operation with a lot of cracks and gaps in the current slab. This study used a new soil investigation with advanced laboratory tests and in situ plate load tests. In calculation, four cases of the strategy were investigated to predict the real behavior and the time-dependent settlement. The results show that the consolidation settlements of the D-box method were 112.62 cm, 205.28 cm, 219.57 cm, and 287.12 cm for case 1, case 2, case 3, and case 4, respectively. The settlement of the second year increased about 2% in comparison with the one of the first year, and this process performed that case 1 was suitable for the observed settlement behavior of D-box ground-treated system.
