Abstract

In this research we try to propose a new method for rock slopes stabilization and underground structures support of a real project that uses mesh reinforced shotcrete to improve value index of it. For this we applied value engineering technique on a real project of IRAN (EZGELEH dam) to help us use specific and accurate data. Also we used a laboratory research in same field to evaluate effect of project on quality and efficiency of final result. At the end we constructed a part of tunnel by suggested method of value engineering and similar part by old method to compare these methods together based on time, cost and quality. Final result of research has three major parts that has been reached by studying on major parameters of project (time, cost, quality). Final result has been presented by specific data and statistics. The results of our investigation show that using polypropylene fiber reinforced shotcrete instead of mesh reinforced shotcrete for rock slopes stabilization and underground structures support upgrade value index of this project significantly. Also it can be used in similar development projects.
