摘要： PROBLEM TO BE SOLVED: To provide a stress transfer device capable of preventing the transfer of bending moment between a pile head and an upper structure without accompanying the rise of a cost and favorably coping with shear force acting between the pile head and the upper structure at that time and a structure making use of the stress transfer device. SOLUTION: A pile head member 5 set on the pile head 2a of a footing pile 2 and a structure supporting member 6 fixed to the upper structure 3 are vertically brought into contact with each other through a contact surface 8 as a part of a virtual spherical surface Sv. At that time, the contact surface 8 is formed in a circular shape with a vertical shaft Va passing through the center of radius of curvature of the virtual spherical surface Sv as the center shaft.

摘要： PROBLEM TO BE SOLVED: To prevent a large bending moment from occurring on a foundation pile by overlapping an upper structure side spherical member having a spherical face along the spherical face of a spherical face member on a foundation side spherical face part provided on the head part of the foundation pile, and having a proper friction resistance between the spherical faces. SOLUTION: The foundation side spherical face member 2 having a projection spherical face 2a is attached to the pile head 1a of the foundation pile 1 embedded in ground 5. The upper part structure side spherical face member 4 having the recess spherical face 4a of curvature along the projection spherical face 2a is arranged on the foundation side spherical face member 2. The proper friction resistance is carried by the contact interface of the projection spherical face 2a and the recess spherical face 4a. Thereby it is rigid connection structure in an intermediate and small-scaled earthquake, and during a large-scaled earthquake, it is the structure having a rotating function while a large bending moment is transmitted. In addition, the safety of the pile head 1a can be secured, the cross sectional force of the foundation pile 1 can be lessened, the foundation pile 1 can have the necessary minimum performance, and construction work is simplified.

摘要： PROBLEM TO BE SOLVED: To keep the function by constructing an underground wall in the bulkhead side ground of a structure situated near a bulkhead, and constructing an underground wall of a form gradually extended toward the structure side on the upstream side in the direction where the lateral flow of ground to the structure is estimated. SOLUTION: An underground wall 5 is constructed in the ground G on a bulkhead 1 side of a structure 2 situated near the bulkhead 1. On the upstream side of the estimated moving direction of the ground, an underground wall 7 is constructed. The underground wall 7 is formed so as to have a substantially V-shaped plane cross section in which it is curved from a top end part 7a to both side end parts 7b of the structure 2. It is gradually minimized from the upper part toward the lower part to approach the top end part 7a to the structure 2 side. According to such a structure, even when a ground G' is liquefied according to the movement of the bulkhead 1 by earthquake, or the ground G on the opposite side is liquefied, its effect can be prevented from being extended to a foundation 3. Further, the liquefied ground G can be smoothly guided to both the sides. Thus, the term of works and the construction cost can be suppressed to a minimum.
