摘要： PROBLEM TO BE SOLVED: To reduce the number and specifications of foundation piles so as to obtain economical effect by providing a pile reaction device between an upper end part of the piercing foundation pile and a hole provided in a foundation bottom slab of a structure, and maintaining ground reaction and pile reaction always to specified allocation. SOLUTION: A pile reaction adjusting device 6 is provided between a head part of a foundation pile 4 and an inner peripheral wall upper part of a hole part 5 piercing a foundation bottom slab 2. In the pile reaction adjusting device 6, a plurality of metallic deformable members 7 of approximately J-shape cross section disposed along the circumferential direction of the foundation pile 4 are respectively fixed through anchor bolts 8 and bolts 9. When the ground 3 goes down due to ground subsidence so as to lower ground reaction acting upon the lower face of the foundation bottom slab 2 and to increase pile reaction of the foundation pile by that portion, the deformable members 7 are deformed against load of the specified value or more, and the foundation bottom slab 2 subsides following ground subsidence. The ground reaction of the foundation bottom slab 2 can therefore be set back to the original value so as to be able to realize foundation pile design based on resultant force of ground reaction and pile reaction.

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.
