Block Resonance Test on Geosynthetic Reinforced Foundation Beds
The present study investigates the efficacy of geosynthetics in improving the performance of machine foundation. A series of block resonance tests were conducted over the soil beds reinforced with the different type of geosynthetics. Three different cases, namely, unreinforced, geogrid reinforced, and geocell reinforced cases were considered. The experimental results have shown that the performance of geocell is more effective than geogrid and unreinforced conditions. In the presence of geocell, the displacement amplitude and peak particle velocity were reduced by 53% and 46% respectively, as compared to the unreinforced condition. Similarly, the maximum improvement in resonant frequency of the unreinforced soil bed was observed in the presence of geocell reinforcement. Further, the resonant frequency obtained from the field study was compared with the analytical solution derived from mass spring dashpot model. The resonant frequency obtained from the analytical solution has shown good agreement with the frequency obtained from the experimental study.
