This article contains the research results in the evaluation of a mathematical model for the determination of the compressibility coefficient of the soils of the lacustrine deposit of the city of Tunja, Colombia, through the execution of one-dimensional consolidation tests, complementary with soil classification tests characterizing its index properties, stories as a ratio of voids, porosity, specific gravity and consistency limits, where a selection of different sites located covering the general area of the lake deposit is made, taking soil samples unaltered at different depths, where processed these soil samples for later geotechnical evaluation. A series of mathematical expressions were generated to determine the approximate shape of the compression coefficient, depending on the index properties, discretizing according to the type of soil, where for this case clays of low and high plasticity were found as silt of high plasticity. These models will serve as a tool to determine the approximate and preliminary form of the magnitude of the main compressibility coefficients.
