Abstract
Soil liquefaction is a phenomenon in which saturated soil completely loses its strength and hardness due to the intense stress applied to it and behaves like a liquid. The results show that for each type of liquefaction, depending on the geology of the soil, the appropriate method should be used to deal with liquefaction. If it is necessary to construct a structure on a soil prone to liquefaction, the structure must have high ductility so that it can adapt to the settlements caused by liquefaction. It is necessary to devise measures for the foundation of the structure to prevent differential settlements. It is necessary for all elements and components of the surface foundations to be well connected to each other so that they behave as a single unit during displacement and settlement. If possible, it is better not to construct a project on a soil that is prone to liquefaction according to existing regulations; Otherwise, all necessary measures, depending on the conditions, must be carefully designed and implemented to prevent consequences such as settlement and instability of the structure during an earthquake and to ensure that the structure maintains its stability during an earthquake. All of the above-mentioned issues are discussed in detail in this study.
