摘要： PROBLEM TO BE SOLVED: To provide a piled-raft foundation with superior earthquake resistance without improving a ground.
SOLUTION: In this piled-raft foundation 10, a structure 12 is constructed on a soft ground 16. The soft ground 16 is a soft viscous soil ground in a normal consolidation state or in a state near that state in which consolidation settlement is produced by the weight W of the structure. The soft ground 16 is not improved. The base of the structure 12 is a direct base 14, and first piles 22 are embedded just beneath the columns 28 of the structure 12. The first piles 22 are cast-in-place concrete piles, PHC piles, or steel tube piles, and have a length reaching a hard support ground 20, and the bottom ends of the piles are embedded into the support ground 20. Second piles 24 are embedded into the lower surfaces of the slabs and beams of the direct base 14. The second piles 24 are PHC piles or steel tube piles, and have a length reaching an excessively consolidated ground 18 with less consolidation settlement, and the bottom ends of the piles are embedded into the excessively consolidated ground 18. The length of the second piles 24 is shorter than that of the first piles 22.

摘要： PROBLEM TO BE SOLVED: To provide a method of setting a shared load shared by the piles of a piled raft foundation.
SOLUTION: The ratio of the center-to-center distance s to the diameter d of a frictional pile 20 (s/d) is obtained, and the shared rate α
p of the frictional pile 20 is obtained from the characteristics shown by the broken line A in Fig.2. Next, the shared load of the frictional piles 20 is calculated from the shared rate α
p of the frictional pile 20 and a known load on a structure 14. Next, using the calculated shared load, the diameter and length of the frictional pile are designed according to ground conditions using a method of designing normal frictional piles. Therefor, the piled raft foundation 10 using the frictional piles 20 can be designed. Next, the designed piled raft foundation 10 is evaluated. The evaluation is performed by estimating the sunk amount of the designed piled raft foundation 10 and determining whether the sunk amount meets the requirement or not. When the sunk amount meets the requirement, the detail design is performed. When the sunk amount does not meet the requirement, the diameter and length of the frictional pile are designed and evaluated again.

摘要： PROBLEM TO BE SOLVED: To construct a soil improved foundation which has high safety for the ground subsidence or an earthquake and is inexpensive in a short term of works by establishing the foundation with strength and scale for supporting the vertical load and horizontal force of a structure, and complementing a pile body in the range of a soil improved foundation to be used jointly. SOLUTION: The vertical sectional area and the lower end depth of a soil improved foundation 1 are set in consideration of the size of the plane area in such a manner that the allowable support force of a soft foundation 15 exceeds the load of a structure 2. The load of the structure 2 above the earth removable weight based on the penetration depth H of a floating foundation 2a is transmitted to the ground to reduce the shearing stress and tensile stress generated in the improved foundation 1. Accordingly, the occurrence of cracks, high bending and shearing rigidity of the foundation itself can be utilized as a part of the rigidity of the foundation slab 2b for a long period of time. Thus, the foundation is behaved as a high-rigidity raft foundation 1 taking the lower end of the integrated improved foundation 1 as the base so as to obtain the foundation with smaller differential settlement and high stability.

摘要： PURPOSE:To obtain an executing method for cast-in-place concrete pile applied to a bearing pile or the like for the foundation of a building. CONSTITUTION:A reinforcement cage is inserted into a pile hole excavated in the ground, and concrete is deposited there. The feeding of the concrete is once stopped at a stage where an unit quantity of the concrete 3 has been deposited through a concrete depositing tremie pipe 22, and compressive force is given to the top of the deposited concrete 3 by a pressurizing device 8 set at the tip of the tremie pipe 22 to pressedly tighten the concrete. After that, the feeding of the concrete is resumed to deposit the unit quantity of the concrete, and these processes are then alternately repeated to complete the construction of the pile body. Thus pressure tightening effect is sufficiently displayed at the every depositing of the unit quantity of the concrete to improve the quality of the pile body concrete 3 and to increase its strength. The concrete 3 is well spreaded into every corner even when an impermeable film having grown on the wall surface of the excavated hole exists. thus adhesion between the ground 1 and the concrete 3 can be improved, and frictional resistance on the periphery of the pile thereby grows stronger to wholly strengthen pile bearing force.

摘要： PURPOSE:To obtain an executing method for cast-in-place concrete pile applied to a bearing pile or the like for the foundation of a building. CONSTITUTION:In an executing method for cast-in-place concrete pile by which a pile hole 2 is excavated in the ground 1, and a reinforcement cage is inserted into the excavated pile hole 2 and set there, and concrete 3 is deposited to construct a pile body, compressive force is given to the top of the pile body concrete 3 to pressedly tighten it immediately after depositing it. Thus the quality of the pile body concrete 3 can be improved and its strength is increased, and moreover the concrete 3 is spreaded into every corner even when an impermeable film 21 having grown on the wall surface 20 of the excavated hole 2 exists. Adhesion between the ground 1 and the concrete 3 is therefore intensified, and the slackness of the ground is tightly fastened to increase frictional resistance on the periphery of the pile. Thus pile bearing force is wholly strengthened to contribute to the execution of a large scale construction, and the diameter and length of the pile can be relatively shortened for improvement in economic efficiency.

摘要： PURPOSE:To effectively transfer a load, by attaching a reinforcing plate to a steel member in parallel with the actuation direction of an axial force and by protruding a reinforcing material like a stud dowel at right angles to the actuation direction of the axial force. CONSTITUTION:A reinforcing plate 3 is attached to both sides of the middle of the web of a H-form steel 1 in parallel with the actuation direction of the axial force and stud bowels 4 are protruded within the anchorage length (m) at right angles to the actuation direction of the axial force. And a reinforcing member made of nonparallel steel rods symmetrical with respect to a vertical line are fitted on either one or both faces of the steel member 1 and the reinforcing plate 3. In this way, the transfer capacity of load and the economical efficiency can be increased.

摘要： PURPOSE:To facilitate design and execution by inserting H section piles among piles of pile rows, forming foot protections in the bearing subsoil, and providing bond force increasing ribs to the lower ends of the H section piles. CONSTITUTION:Soil cement piles 2 having such a depth as reaching the bearing subsoil 1 from the ground are partially overlapped to continue in the shape of a wall, and a plurality of soil cement piles are built. After that, H section piles 3 as heartwood are inserted among the pile 2, and foot protections 4 of the H section piles 3 are formed in parts of the bearing subsoil 1. Vertical force loaded to the H section piles 3 is positively transferred to the bearing subsoil 1 through the foot protections 4. In addition, frictional force increasing ribs 5 with the foot protections 4 are inclined to an angle to prevent bleeding in the event foot protection liquid is hardened and are provided to parts buried into the foot protections 4 of the lower ends of the H section piles 3. According to the constitution, the unification of the H section piles 3 and foot protections 4 can be promoted.
