A settlement analysis has been carried out for several sectors of a rail station yard improved with prefabricated vertical drains (PVD) in Istanbul, Turkey, that exhibited prolonged consolidation beyond the predicted values certain treated zone. Final and End Primary (EOP) times have estimated theoretically as well using Asaoka graphical procedure. The compliance settlement-time curves in-situ ...

Based on an actual excavation of a metro station in Tianjin, China, fluid–solid coupling numerical model was developed to study the characteristics groundwater flow and strata movement induced by dewatering considering barrier effect pre-existing adjacent underground structures. Two parameters were selected for model: distance between existing structure (D), buried depth (H). By comparing distr...

This work has focused on the possibility of being able to consider the behavior of the caprock, such as a layer of cohesive soil that absorbs and transfers the displacement due to the expansion of the aquifer subject to the action of the flow of CO2 at high pressure, but lower than the overburden of the geological formations overlying the caprock. Assuming a caprock saturated unconfined lateral...
