摘要：
A method for producing cylindrical hollow bodies bearing on the ground along one generatrice, of large cross sectional area, by assembling on site previously prepared longitudinal components.The method consists in determining by calculation the optimum cross-sectional profile of said hollow body as a function of known parameters concerning the site, conditions of use of said hollow body and its inherent characteristics; divising said optimum cross-sectional profile into adjacent sections each corresponding to a longitudinal component of the hollow body and together providing a substantially continuous interior surface; and giving the transverse wall section of at least some of said components a variable thickness for adapting the latter component to the stresses to be exerted thereon.
