Abstract

LA SOLUCION PRINCIPAL QUE SE PRESENTA A PROTECCION, A GRANDES RASGOS CONSIDERA UN DURMIENTE UNICO OPAVIMENTO CONTINUO (1), EN HORMIGON ARMADO, SOBRE EMPLANTILLADO CONTINUO (4) EN HORMIGON, DOBRE SUBRASANTE (5) DE SUELO DE ROCA, E INCLUYENDO DICHO PAVIMENTO UNAS BARRAS (2) DE ACERO DE REFUERZO LONGITUDINAL Y TRANSVERSAL, SUPERIOR E INFERIOR, Y BARRAS (3) DE ACERO DE REFUERZO EN BORDE; CON CAPACIDAD ESTRUCTURAL PARA RESISTIR LAS CARGAS DE UN TREN A ALTA VELOCIDAD, Y EFECTOS AMBIENTALES COMO RETRACCION-FLUENCIA, CONTRACCION POR CAMBIOS DE TEMPERATURA Y HUMEDAD, EVENTOS SISMICOS, Y SALINIDAD; ESTANDO ADEMAS DICHO DURMIENTE UNICO O PAVIMENTO CONTINUO (1) CARACTERIZADO PORQUE COMPRENDE: I. UN HORMIGON PREMEZCLADO Y AUTOCOMPACTANTE ENTRE LOS GRADOS H25 Y H50, CON ANCHO 2,5 M ( 1 VIA) Y 7,5 M (2 VIAS) Y CON ESPESOR ENTRE 20 CM Y 40 CM; Y II. UNAS BARRAS (2) DE REFUERZO LONGITUDINAL Y TRANSVERSAL, SUPERIOR E INFERIOR, Y UNAS BARRAS (3) DE REFUERZO EN BORDE, DE ACERO GRADO AT56 O ENTRE GRADOS A63 Y A120, CON CUANTIA LONGITUDINAL O TRANVERSAL ENTRE 0,006 Y 0,012, CON DISTANCIA ENTRE SI DE 10 CM APROX. Y CON DIAMETRO ENTRE 8MM Y 18 MM; Y III. UN EMPLANTILLADO CONTINUO (4) EN HORMIGON PREMEZCLADO Y AUTOCOMPACTANTE ENTRE GRADOS H5 Y H10, CON ESPESOR MINIMO DE 5 CM Y MAXIMO SEGÚN LA RASANTE DE LA VIA, CON TALUDES ENTRE 45° Y 60° CON RESPECTO A LA HORIZONTAL Y CON ANCHO SUPERIOR DE 3M (1 VIA) Y 8 M (2 VIAS) RESPECTIVAMENTE. THE MAIN SOLUTION THAT IS PRESENTED FOR PROTECTION, A GREAT RISK, CONSIDERS A SLEEPING SINGLE CONTINUOUS OPAVEMENT (1), IN CONCRETE CONCRETE, ON CONTINUOUS PLUG (4) IN CONCRETE, OVERLOADING FLOOR (5) OF ROCK FLOOR, INCLUDING BARS (2) OF LONGITUDINAL AND TRANSVERSAL, SUPERIOR AND LOWER REINFORCEMENT STEEL, AND BARS (3) OF EDGE REINFORCEMENT STEEL; WITH STRUCTURAL CAPACITY TO RESIST THE LOADS OF A HIGH-SPEED TRAIN, AND ENVIRONMENTAL EFFECTS AS RETRACTION-FLUENCE, CONTRACTION FOR CHANGES OF TEMPERATURE AND HUMIDITY, SEISMIC EVENTS, AND SALINITY; BEING ALSO SUCH SINGLE SINGLE OR CONTINUOUS PAVEMENT (1) CHARACTERIZED BECAUSE IT UNDERSTANDS: I. A PRE-MIXED AND SELF-COMPACTING CONCRETE BETWEEN GRADES H25 AND H50, WITH WIDTH 2.5 M (1 VIA) AND 7.5 M (2 VIAS) AND WITH THICKNESS BETWEEN 20 CM AND 40 CM; AND II. SOME BARS (2) OF LONGITUDINAL AND TRANSVERSAL, SUPERIOR AND LOWER REINFORCEMENT, AND SOME BARS (3) OF EDGE REINFORCEMENT, OF GRADE STEEL AT56 OR BETWEEN GRADES A63 AND A120, WITH LENGTH OR TRANVERSAL QUANTITY BETWEEN 0.006 AND 0.012, WITH DISTANCE IF OF 10 CM APPROX. AND WITH DIAMETER BETWEEN 8MM AND 18 MM; AND III. A CONTINUOUS EMPLANTILLING (4) IN PRE-MIXED AND SELF-COMPACTING CONCRETE BETWEEN GRADES H5 AND H10, WITH A MINIMUM THICKNESS OF 5 CM AND MAXIMUM ACCORDING TO THE RASANTE OF THE ROAD, WITH TALUDES BETWEEN 45 ° AND 60 ° WITH REGARD TO THE HORIZONTAL AND SUPERCHOUND WIDTH 3M (1 VIA) AND 8 M (2 VIAS) RESPECTIVELY.
