Site based soil amplification and liquefaction analysis: A case study on Uydukent settlement area Afyonkarahisar

One of the important factors causing damage in structures under dynamic loads is local soil properties. The main reason for ground problems such as loss of bearing power, liquefaction, sitting is the change of these properties during the earthquake. It is particularly affected by parameters such as soil amplification, bedrock depth, thickness and type of ground layers, dynamic properties of the ground, discontinuity of layers and topographic structure of the region. In order to prevent structural damages caused by soil augmentation or to reduce their negative effects, it is of great importance to investigate how soil will behave under these loads depending on local soil conditions, to make and evaluate soil augmentation analyzes in advance. This study aimed to investigate the effect of local soil conditions on the soil amplification, bedrock outcrops chosen as the place of action in accordance with Regulation 11 Turkey Earthquake Building a dynamic analysis using different dimensional seismic data was conducted. For this purpose, firstly 124 different drilling data made in the region were evaluated and local soil characteristics were determined. DEEPSOIL software was used to examine the effect of the determined local soil properties on dynamic behavior. One-dimensional Equivalent linear and nonlinear analyzes were performed and different amplification values were obtained for each drilling and the results of the analysis were compared. Magnification is applied with the empirical methods analyzed, the analysis and empirical results are compared. For the formation of pore water pressure obtained as a result of nonlinear ground dynamic analysis. It is mapped separately among Geographic Information Systems. Using nonlinear analysis method; It is thought that it will reduce the cost of designing building foundations under earthquake effect, defining local ground classes and determining the ground parameters to be used in the design of retaining structures and slopes. Within the scope of efforts to reduce earthquake damage, it is planned to determine safe settlements for Afyonkarahisar uydukent region, considering that urbanization and population are concentrated in the study area.
