Modelling of the pore pressure response in sediments due to the movements generated by seismic waves, by means of the spectral element method

"Earth's materials such as rocks and soil are not a completely homogeneous medium, they have discontinuities inside their inner structure known as pores or voids, which typically are filled with a fluid. The pressure exerted by the trapped fluid inside the voids its known as pore pressure....

description "Earth's materials such as rocks and soil are not a completely homogeneous medium, they have discontinuities inside their inner structure known as pores or voids, which typically are filled with a fluid. The pressure exerted by the trapped fluid inside the voids its known as pore pressure. This groundwater pressure within a soil or rock responds to the medium's stress field, following a coupled diffusion-deformation pehomena between the solid part of the system and the fluid one. A well known and effective mechanism that can generate variations on the stress setting along sediments is the cyclical action of earthquakes generated by telluric movements. Usually, soils fail under stress conditions that surpass their bearing capacity, but it is not the only way the sediments can reach failure. When the pore pressure varies at a critical rate or reaches a certain critical value, failure can occur in terms of fracture or soil liquefaction. The last one corresponds to a very hazardous mass movement where the saturated sediments act as a pseudo-liquid material. Therefore, the study of pore pressure variations in saturated soil turns into a relevant topic when treating sediment failure or studying the mechanical response of the porous media. This work describes the process developed to model the pore pressure response in sediments due to the action of seismic waves, by means of the finite element method (FEM). The goal of the project is to analyze the pore pressure diffusion in sediments and how it influences the first stages of soil liquefaction as well as compare the pore pressure response between different sediment models and predict their sensibility to pressure variations and soil failure."--Tomado del Formato de Documento de Grado.

La presion que ejercen dichos fluidos atrapados, contra las preded de la matriz porosa se conoce como presion de poro. La presion de poro responde al estado de esfueros del medio poroso, siguiendo un pareja de fenomenos acoplados de difusión-deformación entre las partes solidas y fluidas del sistema. Un mecanismo bien conocido y efectivo que puede generar variaciones en el estado de esfuerzos a lo largo de estructuras de sedimentos es la accion ciclica de los sismos, generados por movimientos telúricos. Usualmente los suelos alcanzan su criterio de falla cuando las condiciones de esfuerzo a las cuales se ven sujetas, superan la capacidad portante del mismo. Cuando la presion de poro varia a tasas muy altas o alcanza valores criticos el suelo puede fallar, ya sea en terminos de fractura o de licuefaccion. Este ultimo corresponde a un fenomeno en el cual el suelo se comporta como un pseudo liquido, generado movimientos en masa de alto riesgo. Por este motivo el estudio de la variacion en la presion de poro en suelos saturados se convierte en un tema de alta relevacion, cuando se trata de escenarios de falla o en el caso del estudio de la respuesta mecanica del medio poroso. El trabajo en cuestion, describe el proceso desarrolado para modelar la respuesta de la presion de poro en sedimentos, debido a la accion de las ondas sismicas por medio del metodo de elementos finitos. El objetivo del proyecto es analizar la difusion de presion de poro en suelos y ver como afecta los escenarios iniciales de licuefaccion, asi como predecir la sensibilidad de los diferentes modelos de suelo ante las variaciones de presion y su influencia en la falla del sistema."--Tomado del Formato de Documento de Grado.GeocientíficoIngeniero CivilPregrado42 hojasapplication/pdfengUniversidad de los AndesGeocienciasIngeniería CivilFacultad de CienciasFacultad de IngenieríaDepartamento de GeocienciasDepartamento de Ingeniería Civil y Ambientalinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaModelling of the pore pressure response in sediments due to the movements generated by seismic waves, by means of the spectral element methodTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPLicuefacción de suelosMecánica de suelosMateriales granuladoMétodo de elementos finitosTectónica de placasGeocienciasPublicationhttps://scholar.google.es/citations?user=3QCeJHwAAAAJvirtual::17594-1https://scholar.google.es/citations?user=9Mm7xv4AAAAJvirtual::17595-10000-0002-1600-6445virtual::17594-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000054450virtual::17594-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000246379virtual::17595-14dafb0f7-569a-4cb5-bd0a-3a5494a93309virtual::17594-176fcc284-15ff-46ea-8bd7-c7f7cf3cb821virtual::17595-14dafb0f7-569a-4cb5-bd0a-3a5494a93309virtual::17594-176fcc284-15ff-46ea-8bd7-c7f7cf3cb821virtual::17595-1THUMBNAILu826995.pdf.jpgu826995.pdf.jpgIM Thumbnailimage/jpeg11084https://repositorio.uniandes.edu.co/bitstreams/3c833e60-61a0-4797-a584-56043b81c2e7/download3b42678e0e97ee4663b9a6222d660618MD55ORIGINALu826995.pdfapplication/pdf2610395https://repositorio.uniandes.edu.co/bitstreams/0e235974-40c2-452f-8a34-5ee4b90d88c0/download2a69dfb04835f0f0097cdbd5c5be90daMD51TEXTu826995.pdf.txtu826995.pdf.txtExtracted texttext/plain66560https://repositorio.uniandes.edu.co/bitstreams/d429d12b-b7c3-4852-8bcd-cce3905fa880/download30c748db59de4f28736e4e09ab57a2baMD541992/45819oai:repositorio.uniandes.edu.co:1992/458192024-03-13 16:03:53.184http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co
