This study used finite element analysis to investigate the influence of using two reinforcing systems, geogrid and grid anchor, on bearing capacity a circular footing resting sand. The parameters studied were effect number reinforcement layers (N), depth ratio topmost layer (u/d), vertical spacing between consecutive (h/d), length (L). results showed that layout had very significant behavior re...

The use of geosynthetic reinforcement to enhance the ultimate load-bearing capacity and reduce anticipated settlement shallow foundation has gained sufficient attention in geotechnical field. improved performance is achieved by providing one or more layers geosynthetics below foundation. full wraparound technique proved be efficient for confinement soil mass reduction however lacks literature a...

In order to obtain the optimal spacing of closely spaced footings under cyclic dynamic loading, model tests were carried out on unreinforced and reinforced sand foundations. The influence center point (S) bearing capacity foundation load is discussed. test results show following: (1) peak largest when S/B = 2.0 (B width footing), ultimate 20% higher than that foundation. (2) vertical soil press...

Various methods can be applied to improve soil behavior in order increase the bearing capacity or reduce settlement of footings. These categorized as stabilization improvement by use different geosynthetics; injection methods; grouting replacing weak with stronger materials. One most common and materials that used for improving soils, is placing a stone layer under footing. In this study, strip...

Two-dimensional model tests combined with PIV technology were conducted to study the failure behavior of strip footing on geosynthetic-reinforced granular soil foundations a mesoscale. The results showed that geosynthetic reinforcements improve bearing capacity foundations; however, effectiveness reinforcement was affected by position, length, and number geosynthetics. mesoscale factor affectin...
