Numerical analysis examination about pile group efficiency of steel pipe pillar foundation that supports steel pipe collection bridge pier
Satoru Ohtuka
The steel pipe collection bridge pier is a structure made one pillar by the shearing panel that has the history type damper function to assume four steel pipes to be a basic unit. Moreover, it proposes the steel pipe pillar foundation as a rational structure of the basic part of the steel pipe collection bridge pier structure. It is thought the steel pipe pillar foundation is a structure here that integrates an upper worker, a lower worker, and the basic part, and it is effective to making to compact and the rationalization of the base part. In addition, it is necessary to take the influence of the pile group efficiency into consideration on the structure of the stake foundation, and a relation with a stake interval is verified by numerical analysis.
Based on the above, steel pipe pillar foundation form is set as the basic of a steel pipe collection bridge pier, the grasp of the transformation characteristic and the evaluation of the pile group efficiency are verified, and this research examines the structure that is more rational and safety is higher.
