Effect of load transferring platform on micropile

Effect of load transferring platform on micropile Due to the incapability nature of sustaining high loads in soft soil, micropiles are seeking the attention of various researchers, geotechnical engineers, practitioners, and builders. It is well-established that a group of micropiles increases the bearing capacity of soft soil, but the amount of increment is less than that of the pile does. That means micropiles can’t replace the piles exactly. Therefore, in the present study, one load transferring platform (LTP) was placed over the group of micropiles, which distributed the load uniformly on micropiles to increase the bearing capacity of micropiles. The load transferring platform was prepared by using locally available loamy soil and Ordinary Portland Cement. In this context, a set of experimental studies was conducted to obtain the optimum amount of cement mixed with soil and water. Laboratory experiments were also conducted to obtain the mechanical behavior of the cement-treated loamy soil, soft clayey soil, and soil–cement mixture. Then, by using these experimental results, the numerical investigation was performed by using the software PLAXIS-2D to observe the load transferring mechanism over the micropile. The resulting trend showed a significant improvement in bearing capacity of soft soil after placing the soil cement bed over the micropiles. The resulting outcomes found to have similar trends as reported in existing studies with respect to micropile. The parametric studies were also conducted with the numerical results to obtain the effects of micropile spacing (s), thickness of SCB (t), length of micropile (l). The resulting parametric studies showed encouraging outcomes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Building Pathology and Rehabilitation Springer Journals

Abstract

Due to the incapability nature of sustaining high loads in soft soil, micropiles are seeking the attention of various researchers, geotechnical engineers, practitioners, and builders. It is well-established that a group of micropiles increases the bearing capacity of soft soil, but the amount of increment is less than that of the pile does. That means micropiles can’t replace the piles exactly. Therefore, in the present study, one load transferring platform (LTP) was placed over the group of micropiles, which distributed the load uniformly on micropiles to increase the bearing capacity of micropiles. The load transferring platform was prepared by using locally available loamy soil and Ordinary Portland Cement. In this context, a set of experimental studies was conducted to obtain the optimum amount of cement mixed with soil and water. Laboratory experiments were also conducted to obtain the mechanical behavior of the cement-treated loamy soil, soft clayey soil, and soil–cement mixture. Then, by using these experimental results, the numerical investigation was performed by using the software PLAXIS-2D to observe the load transferring mechanism over the micropile. The resulting trend showed a significant improvement in bearing capacity of soft soil after placing the soil cement bed over the micropiles. The resulting outcomes found to have similar trends as reported in existing studies with respect to micropile. The parametric studies were also conducted with the numerical results to obtain the effects of micropile spacing (s), thickness of SCB (t), length of micropile (l). The resulting parametric studies showed encouraging outcomes.
