COMPLEX ANALYSIS IN THE RIVER BASIN OF TOPLI A AND TECHNOLOGICAL SOLUTIONS FOR SLOPES STABILIZATION

Landslides distribution is differentiated function of various causal factors or conditions (litology, declivity, land use,precipitations). For each factor, it can be depicted some homogeneous areas, with numerical coefficients, in a incresingsuccession (1 – very high; … 5 – very low), using the GIS. The complex arrangement involves the analysis and diagnosisof watershed planning, establishing its vulnerability to the action of natural and anthropogenic factors. New technologiesfor earth reinforcement with other engineering works to stabilize the slopes, are durable works because the chemicalproperties of high density polyethylene, which does not react with any other environmental component (ex. earth geogridreinforcement). New technologies for earth reinforcement executed in complex with other engineering works to stabilizethe slopes, are durable works because the chemical properties of high density polyethylene, which does not react withany other environmental component. Using special technology to stabilize determined substantial time and cost savingscompared to traditional solutions. The landscape of slopes reinforced with geogrids, due to external quality topsoil isclearly superior to the classical solutions of stabilization.
