要旨 :
鋼管矢板ウエル工法は,現在までに当社水島製鉄所No.1,No.2,およびNo.3溶鉱炉基礎に採用されているが,ここではNo.2溶鉱炉の基礎の設計を中心に設計の考え方や実測による設計の妥当性を検討し,従来の重力式構造に対して有力な新工法であることを実証している。
Synopsis :
In both phases of designing and construction of a blast furnace foundation, one of the most important substructures in a steel plant, the engineers' greatest concern has rightly been how to support its top heavy gravity and how to increase its stability against earthquakes. The present authors were favored with the opportunities of both designing and executing the construction of the foundations of No.1, No.2 and No.3 blast furnaces of Mizushima Works by the "Walled Steel Pipe Pile Well Method." This unique method was developed for the first time in 1965 by the engineers of Kawasaki Steel Corporation, and has since been improved year after year to attain its present stage of near perfection. The present paper introduces the outline of the "Walled Steel Pipe Pile Well Method" with main reference to the design of No.2 blast furnace of Mizushima Works, including the design techniques according to the bearing capacity of the walled steel pipe pile well in gravels, the study of subsoils, and comparisons between the estimated figures and the measured figures, etc.
