RESUMEN: El módulo de corte máximo (Go) es un parámetro dinámico de los suelos importante en diseños geotécnicos que se puede calcular a partir de la medida de la velocidad de la onda de corte (Vs). Los ensayos cross-hole y down-hole pueden ser utilizados para medir Vs. De acuerdo con la literatura, los ensayos de piezocone sísmico se han mostrado un método rápido, económico y confiable para determinar Go y se puede asumir que los ensayos down-hole y cross-hole conducen a resultados similares. En este artículo se describe brevemente un sistema desarrollado para realizar ensayos down-hole luego después de la realización de un ensayo CPTU, utilizándose la misma perforación. A pesar de todos los beneficios de lo ensayo down-hole, el registro y la interpretación de dados sísmicos no son tan sencillos. En este trabajo, se presenta el procedimiento del ensayo y su interpretación para el sistema desarrollado para garantizar la calidad de los valores de Vs medidos, destacándose los aspectos más preocupantes del ensayo.
