Effect of Different Soil Saturation Conditions on The Ultimate Uplift Resistance of Helical Pile Model

Helical piles have many properties over the other types of piles systems include high tensile capabilities, the possibility of fast installation, applying load immediately after installation, and suitability for most soil's condition. In addition to that, helical piles have relatively less nois...
