Setsunan University}, month = {Feb}, note = {There are two problems, construction problems and planning problems when performing the additional pile system, but in order to solve the construction problems first, we focused on the joining conditions of the old and new foundations, and did not lift the main muscles of the footing so that construction could be easy. We aim to develop a rational construction method that only requires surrounding the existing footing. Furthermore, by elucidating the load-sharing mechanism of the new foundation using the existing pile and the pile, we will establish a design method for the increased pile construction method. In addition, by covering the footing of the existing foundation with a steel outer shell, it is possible to reduce the occupied area at the time of construction, We will also examine the usefulness of a structural format that integrates the footings without joining each other by increasing the number of steel frame construction guides and embedding them in the footing. In this research, we conducted a 50 G field static horizontal loading experiment that makes it possible to reproduce the same self-weight stress state as the real thing. In combination with the knowledge obtained from the previous centrifugal loading model test, we aim to elucidate the influence of the joining conditions of the existing piers and the upper surface of the steel outer shell of the proposed new pile construction method on the load-sharing mechanism of the existing pile and the additional pile.}, pages = {44--61}, title = {新たな増し杭工法による補強効果に関する遠心模型実験}, volume = {8}, year = {2023}, yomi = {タナカ, マサヒロ and テラモト, シュンタロウ} }
