Análisis de estabilización de movimiento de ladera aplicado en el sector La Urna del barrio Chontacruz - Loja

Abstract

Abstract:The research project is oriented to the analysis of slope movement stabilization applied in the La Urna sector of the Chontacruz - Loja neighborhood. Thus, it was determined that geologically the movement is located on the Quillollaco formation, which is made up of conglomerates and sandstones. On the other hand, in reference to the geotechnical part, it was considered that stratigraphically there are three types of materials and they are under a hydrology that is considered to be a problem of slope movement. Consequently, FS and SRF were calculated and varied according to various scenarios by Morgenstern and Price and Finite Element analysis. The results show that under current conditions the movement does not reflect a steady state. Therefore, the geometric modification of the slope movement was established by means of berms, development of a drainage system considering horizontal and longitudinal drains, and finally the implementation of S 460 NH type corrugated steel bolts. With these mitigation measures the slope reflects a safety factor of 1.58.
