| Summary: | Rain events are the cause of many landslides that occur on slopes causing a loss of strength by decreasing the effective tension. In this article, it performs the geo-mechanical characterization of a soil slope located in Colombia which has been defined as a zone of instability, where there is instrumentation consisting of a volumetric soil moisture meter and a pluviometric station. With this information, we intend to determine the times of saturation and evacuation of rainwater in the mentioned soil considering too the frequency of events. In that sense, an experimental calibration of moisture meter installed on the site is done, and the Water Retention Characteristic Curve is constructed to determine the variation of the effective efforts as soil moisture and permeability of the material and the relationship is a determined index empty as soil structure to know its maximum saturation level. The main results showed an increase in the correlation of soil moisture as depth increases, on the other hand, the permeability coefficient obtained was low, which is typical of soils with low permeability, a situation that was also evidenced in the differences of the suction curves obtained; additionally it was found that at greater depths more accumulated precipitation is required to reach saturation moisture, which corresponds to the infiltration process in the soils, the void ratio found and the mentioned permeability coefficient. |
