Studies of the effect of ground settlement on the buried pipe including a part passing through the building wall

摘要

Wide or local deformation of the buried pipe line occurs by the change in ground condition caused by various reasons. For example, at the time of earthquakes, lateral spreading and also subsidence of the ground are produced by liquefactions caused by strong ground motion. A buried pipe line in which large strain and large stress are produced by the subsidence of the ground is the pipe line including a piping through the penetration part of a wall hole in buildings or abutments. In this study, in order to discuss the most suitable buried pipe line configuration including the building penetration piping, numerical case studies are performed for various types of buried pipe lines including the building penetration piping. And then, by discussing the results of numerical case studies, the tendency of whole pipe line system, appropriate allocation of bend and length of straight pipe are discussed from the standpoint for safety.
