| Popis: | Flexible systems anchored to the ground are low visual impact alternatives to be used in slope protection. With the aim of reducing their installation time and costs the mechanical union between layers of membranes is proposed to be done in warehouses instead of independent installations on site. The most appropriate component selection and linking method is selected using multi-criteria decision analysis, specifically using AHP, WASPAS and TOPSIS techniques. The criteria considered in order to take the decision are cost of materials, ease of sewing, transport and installation of the system, biodegradability of the secondary mat and its hydroseeding retention capacity that stimulates the revegetation. Due to the uncertainty on the data of biodegradability, four scenarios were analysed. The results indicate that the most suitable secondary membrane in all cases is the coconut fibre mesh and should be connected to the main membrane using a cable tie machine. |
