ABSTRACT: From several years ago, the method proposed by Prater (1977) to calculate the lateral pressures acting over shaft linings has been in use. Unfortunately, some algebraic errors have been found in his analytical development. Every step of that development was checked and corrected if errors were found, to find the equations that describe the pressure distribution in accordance to the suppositions made by Prater in his model. The procedure was combined with an analytical method proposed to study the soil-tunnel interaction problem (Romo, 1984). This method includes the phenomenon of interaction lining-soil. The combination of the two methods is made under the hypothesis that the mechanical elements of the shaft lining can be calculated with the analytical solution of the problem of interaction soil-

RESUMEN: Desde hace varios años se ha utilizado el método propuesto por Prater (1977) para el cálculo de las presiones laterales sobre la superficie de lumbreras. Sin embargo, se han encontrado algunos errores algebraicos en su desarrollo analítico. Se procedió a revisar cada paso de dicho desarrollo y a corregir los errores encontrados, para así llegar a las ecuaciones que describen la distribución de presiones de las suposiciones hechas por Prater en su modelo. Se combinó el procedimiento con un método analítico que permite calcular los elementos mecánicos del recubrimiento de túneles (Romo, 1984). Este método incluye el fenómeno de interacción revestimiento-suelo. La combinación de los dos métodos se hace bajo la hipótesis de que los elementos mecánicos del revestimiento de la lumbrera se pueden calcular con la solución analítica del problema de interacción suelo-revestimiento del túnel, considerando las presiones calculadas con el modelo (modificado) de Prater.
