Abstract

Due to rebound from the wall when shooting, the quality of shotcrete varies between before and after shooting. So accurate quantitative evaluation method of quality evaluation is strongly needed above all for the more demand of high quality shotcrete in the near future. From the past many experimental researches or constructional showings on shotcreting, it is empirically said that rebound is caused by various material and constructional factors, but little is clarified about its mechanism as things are. In this paper, the first theoretical approach is attempted; namely, 2-Dimensional Distinct Element Method (2D-DEM) is applied to estimate the amount of rebound. Some parametric studies are employed and the relationship between every parameters and rebound ratio is considered. As a result, application of this new method is verified against the result of our past experiment or general mentions about shotcrete rebound.
