Testing the Performance of a Proposed Geotechnical Based Method in Detection of Liquefiable Soil Layers Subjected to Earthquake Excitations - a Case Study

Abstract:

This Study aims to develop an efficient computational method for evaluation and detection of liquefiable soil layers in a high seismic risk region by considering the importance infrastructures such as earth dams. Several earth dam were affected by happened earthquake in Iran and therefore better knowledge on liquefaction behavior of this type of structures because of providing emergency supplies and ensure structural safety in engineering terms are so important.

In this study on base of a developed C# graphical user interface, a geotechnical based procedure were proposed and applied to Nematabad embankment dam in the west of Iran and an estimation of the liquefaction behavior subjected to Avaj-Changureh earthquake (2002, Iran) vibrations has been carried out. To achieve the target, a careful assessment of the involved parameters in liquefaction analyses is considered and for validation of the applied procedure, a detailed comparison between the obtained results of this study and several known procedures were conducted. The obtained results in this study show good agreement and adaptability with other accepted procedures and also analyzed data indicate that the selected area in some depths is susceptible and prone for liquefaction.
