Validación de programas 1D (Deepsoil, Cyclic 1D y Midas GTS-NX), que realizan estudios de propagación de ondas con el uso de la base de datos sismológica de Japón (NIED), en “columnas de suelos” instrumentadas en el tope y la base del depósito

Abstract

This research work is based on the study of wave propagation using the 1D Deepsoil, Cyclic, and Midas GTS NX programs in Japanese stations instrumented at the top and base of the profile, in order to select the program that best suits the spectral responses measured at the surface. For this purpose, the lithological profile has been characterized according to the bibliographic information consulted. A classification of the lithological columns of the seismological network in NIED-JAPAN (National Research Institute for Earth Science and Disaster Resilience) is made. Of the stations for which geotechnical information and seismological records were available, 21 stations were selected: 5 shallow, 7 intermediate and 9 deep, with instrumental accelerations between 0.1 to 0.2 g, 0.2 to 0.3 g, 0.3 to 0.4 g, 0.4 to 0.5 g and 0.5 to 0.7 g, with epicentral distances of less than 10 km, intermediate distances, of 40 to 60 km and distant distances, greater than or equal to 100 km. For the verification of the programs, we used the comparison of the modeling of response spectra obtained at surface with the real instrumental records that occurred at the top of the deposit. The purpose of this study is to present a site response analysis and to find the best 1D program (Deepsoil, Cyclic and Midas GTS-NX) for wave simulation that is easy to use and access in its data, which will help for the design of future structures and recommendations in its planning and projection.
