Geotechnical Zoning for the Construction of an Irrigation District in the Department of Atlántico - Colombia

Abstract

For the construction of an irrigation district, the geotechnical conditions of the existing soils in the municipality of Ponedera (Atlántico, Colombia) were analyzed, by means of manual sampling and standard permeability test (SPT). This information was processed in a database for analysis. The soil types were obtained, most of which were classified as inorganic clays and silts (CL and ML), to a lesser extent, silty and clayey sands (SM and SC), and maps of soil types zoning and allowable capacity were drawn in GIS. No water table was found in the investigated soil area. Following the guidelines of the Colombian Earthquake Resistant Regulation (NSR-10) and the RAS, the usefulness for future studies has been concluded. Finally, the soil explored can support load capacities at a depth of 3.0 m of 31.8 ton/m2.
