Experimental and Numerical Results

This chapter presents the results of the uplift responses based on experimental test series and numerical analysis, as discussed in the previous chapters. The numerical analyses were performed using PLAXIS as a finite element program. The research involved the numerical and experimental aspects of the uplift capacity of symmetrical anchor plates during uplift tests and their displacement on non-reinforced, reinforced, and grid fixed reinforcement (GFR) reinforced soil. Each aspect of the research is divided into the test series to enable a more systematic approach towards the analysis. Sand was used as an embedment medium in this research. In order to obtain a criterion for density, loosely and densely packed sand were used. Loose packing was achieved by sand raining methods, while dense packing was achieved through hand compaction via electrical vibrator. Results obtained from tests conducted using numerical and experimental results will be discussed in this chapter. The effect of embedment ratio, sand density, shape factor, breakout factor, and failure mechanism patterns of models are detailed in non-reinforced, reinforced, and GFR-reinforced soil in numerical and experimental tests. The failure mechanism patterns of models in loose sand and dense sand observed based on experimental and numerical analysis are presented in this chapter.
