We have carried out design of rigid conduit by various analytical methods which are composed of applied earth pressure estimation and structural stability calculation for it. Among them, however, the method which can simulate behavior of a rigid conduit in va- site conditions is not yet found. In this paper, a new formula of applied earth pressure and a new method of structural stability calculation are proposed. Bearing capacity and behavior of a rigid conduit with concrete cradle under buried
