杭体補強を有するソイルセメント複合杭の引抜き抵抗に関する研究

抄録

In recent years, works to improve existing structures and strengthen their seismic resistance have increased. Pile construction in narrow spaces is constrained by the site and the construction process. Therefore, a construction method of soil-cement composite pile using a mechanical agitator was developed. The purpose of this study is to clarify the tensile resistance of the soil-cement composite pile with a reinforcing pile body. This paper briefly summarizes the construction method, then discusses the results of static load tests, and finally summarize the results of simulation by beam-soil spring model. The paper suggests the evaluation method of tensile resistance for the soil-cement composite pile.
