CALCULO DE VOLUMENES
PRACTICA N° 14
Introducción: En la mayoría de los proyectos de ingeniería es necesario hacer algún tipo de excavación o de relleno para preparar el terreno para la construcción de una carretera, edificio, canal, instalación de equipos, maquinaria etc.
Sin embargo a partir de las curvas de nivel, se puede calcular el volumen de una colina, cerro o sistema de montañas, que es el propósito de esta practica, además, tiene aplicabilidad a partir de curvas del subsuelo para el estimativo de recursos mineros o petroleros.
OBJETIVOS:
Conocer y aprender un método para el calculo de volúmenes.
Establecer la aplicación de estos cálculos de manera practica.
Determinar su aplicación en actividades o proyectos petroleros.
PROCEDIMIENTO.
Para calcular el volumen entre curvas de nivel o cualquier otras curvas, cuyas alturas entre si son conocidas, se procede de la siguiente forma:
A450
A500
A600
A650
V = h / 3 ( A 1 + A 2 + A 1 A 2 )
Donde: h= diferencia de altura entre dos curvas (m)
A1 = área curva inferior (m2)
A2 = área curva superior (m2)
Para lo indicado en la gráfica:
V1 = 50/30m (A450 + A500 + A450 . A500 )
V2 = 50/30m (A500 + A550 + A500 . A550 )
V3 = 50/30m (A550 + A600 + A550 . A600 )
Vt = V 1 + V 2 + V 3
