For more than 20 years, problems related to erosive processes and landslides have been detected on Las Cabras hill in Duran, Ecuador. Las Cabras hill has a stability problem due to its sub-vertical slopes (north zone) due to rockfalls, slopes with a favourable slope to landslide (south zone) and two anthropic factors (houses in inappropriate places and a lack of sewer system). From previous studies, Las Cabras has been classified as high to very high susceptibility to landslide (soil) or detachment (rock). Therefore, there is a risk for families living in this area and its surroundings. This study aims to propose engineering solutions through the technical considerations of studies carried out to stabilise the Las Cabras hill and its surroundings. The methodology considers: i) analysis of the results of the engineering studies carried out on the hill, ii) design calculations according to the stability and safety analysis of the slopes employing Hoek and Bray method; and iii) proposal of stabilising solutions in the most susceptible areas of the hill. The solutions have to do with controlling erosive processes and rock masses that can slide or detach. Injected anchors (using gunite and Ø25mm rods) and mechanical drains are proposed to reduce pore pressure in that area. Also, it can be applied in combination with surface channels in the form of a ladder to evacuate rainwater. Ultimately, it is possible to rethink the territorial ordering on Las Cabras hill with these considerations. [ABSTRACT FROM AUTHOR] |
