摘要

In this work, a numerical study using the finite element method has been performed to investigate the effect of two layers of fully wraparound encapsulated reinforcement on bearing capacity when a surface strip footing is placed on sand. A total of 52 numerical simulations with variation in reinforcement layout parameters have been performed to prepare design charts of bearing pressure-settlement ratio curves, and an equation for bearing capacity has been developed using regression analysis. The optimum layout configuration has been observed when reinforcement length-footing width ratio were 2 and 4 and encapsulated layer thickness-footing width ratio were 0.7 and 0.6 for the top and bottom reinforcement layer respectively. The effectiveness of the present double encapsulated reinforced soil system has been studied by comparing the bearing capacity results obtained from this system with the horizontal planar reinforcement system and the partial wraparound reinforcement system. Using the double encapsulated reinforced soil system provides greater bearing capacity and lesser land width, and can be regarded as an economical method where installation can be done easily without any specific machinery. This technique can be suitable for real-life projects to stabilise weak soil beneath structures like embankments, pavements and footings.
