Numerical Analysis and comparison of Micropile’s Pressure Bearing Capacity With the new Microbulb system on clay in Shiraz, Iran
Abstract: In recent decades, the implementation of micro piles have been increased extensively in large project constructions because of the unique advantages of this method compared to concrete piles.The results of centrifuge tests and numerical analysis show that efficiency and importance of micropiles can be considered as an effective functional solution. This research is designed to use a numerical modeling using finite elemet software Plaxis 3d Foundation v1.6 and also the FHWA code for a comparative study between micropiles and microbulbs . then the effective factors was analysed in order to choose the better method for between these two methods(micropile and microbulb). The results showed that the new microbulb system is an appropriate solution for improvement of mechanical properties of the soil ,increase of bearing capacity and settlement decrease.
