This study deals with the performance evaluation of the soil improvement using surcharge preloading techniques with prefabricated vertical drains (PVDs) for the Mahshahr oil storage tanks project as a case study. First, the ultimate settlement values were predicted using observational methods, then, to determine the modified preloading design param...
In his paper, back-analysis using results from instrumentation by finite element software for design of preloading method by embankment with prefabricated vertical drains (PVDs) was used, and the results were compared with each other. Hence, the basic geotechnical parameters obtained by laboratory and field experiments have been modified using this...
In order to improve subsurface soft saturated clayey layers under the oil storage tanks in Mahshahr project, the preloading method by embankment along with prefabricated vertical drains (PVD) with a triangular pattern has been used. To control performance of the embankments, some instruments such as Settlement Plates and Piezometers installed throu...

... Therefore, numerical simulation plays an essential role in estimating effective parameters in the preloading process, such as settlement rate, degree of consolidation, determination of the smear zone properties, and other important parameters. The numerical analysis also has fewer limitations than analytical methods, and it is affordable compared to the executive methods, and many researchers utilize it for practical designs [36][37][38][39][40]. ...

... The empirical correlation can be considered quite logical, since the liquid limit and the shrinkage limit are important parameters controlling the compressibility behaviour. The liquid limit is the extreme limiting water content, above which the forces of the interaction between the particles become sufficiently weak so as to allow the easy movement of the particles relative to each other [74]. The void ratio at the shrinkage limit can be taken as the limiting void ratio, below which the volume change would be insignificant. ...
