Criterios de diseno de pantallas continuas en la ampliacion del metro de Madrid

En la presente comunicacion se analizan los criterios basicos adoptados para el diseno de tuneles y estaciones construidas a cielo abierto en la Ampliacion del Metro de Madrid, con ayuda de pantallas continuas y discontinuas de hormigon armado (cut and cover method). Para ello se estudian las propiedades geotecnicas de los suelos de Madrid, a fin de establecer parametros geotecnicos unificados de proyecto, se muestran las hipotesis hechas para el analisis numerico de las pantallas "in situ" (modelo de calculo, presines del agua, etc.) y se expone la instrumentacion instalada y los resultados obtenidos. (A). Resumen en ingles: CAST IN SITU WALL DESIGN CRITERIA IN THE MADRID METRO EXTENSION. In this paper the basic criteria adopted for the design of tunnels and station built by the cut an cover method for the Underground Madrid Extension is analysed. To this purpose the geotechnical properties of the Madrid soil are studied, in order to stablish the unified design of continuous and discontinuous cast-in-situ walls. Also the hypothesis made for the numerical analysis of these "in sity" walls are shown, together with the installed instrumentation and the obtained results. (A).
