Determinación de parámetros dinámicos y capacidad portante de los suelos usando técnicas de exploración sísmica caso de estudio: Urbanización Valle del Espíritu Santo, Pamplona, Colombia.

Abstract

This research presents the classification of soils using the parameter Vs30m, based on the "title A" of the NSR-10 standard (Ministerio de Ambiente, REGLAMENTO COLOMBIANO DE CONSTRUCCIÓN SISMO RESISTENTE NSR-10 , 2010) and the determination of other parameters such as : Poisson's ratio, Young's modulus, Rigidity modulus and bearing capacity of soils; Starting from the P and S type seismic velocities obtained from the processing, using the techniques of Seismic Refraction Tomography (TRS) and the Multichannel Analysis of Surface Waves (MASW), of the geophysical data previously collected in the Valle del Espíritu Santo urbanization , Municipality of Pamplona, Colombia. The work methodology is developed in four (4) phases: collection of seismic data and specifications of the study area; data reprocessing to obtain P and S type seismic velocities by means of TRS and MASW techniques; analysis and integration of information to determine the dynamic parameters of the soil; obtaining and correlation of geotechnical parameters for soil characterization. For data processing, the SeisImager software was used: "Pickwin" and "Plotrefa" for seismic refraction tomography (TRS) and "Surface Wave Analysis Wizard" and "WaveEq" were used for Multichannel Surface Wave Analysis (MASW).
