摘要： PROBLEM TO BE SOLVED: To provide a method for verifying the bearing capacity of an existing pile on which an extraction force is acting by a pile press-in machine.
SOLUTION: In the method for verifying the bering capacity of an existing pile P when an extraction force has acted on the existing pile P in a pile construction process using the pile press-in machine, a cycle of removing load removal is repeated after a press-in force is loaded and maintained for a prescribe period of time as measuring the amount of displacement of the pile head of the existing pile P on which the extraction force is acting. When the amount of displacement becomes 10 mm or less while the press-in force is loaded and maintained for the prescribe period of time, the press-in force is taken as the bearing capacity of the existing pile P.

摘要： PROBLEM TO BE SOLVED: To provide a method for laser beam butt welding of metallic sheets having different thicknesses, which method can eliminate recessed portions formed on the bottom surface of a welding bead, and does not cause the loss of welding energy even if some clearances exist in butted portions, and can weld tailored blank materials having excellent formability with small electric energy consumption and high productivity. SOLUTION: In the method for laser beam welding, two sheets having different thicknesses are butted in the state that one side surfaces of them are shifted from each other, and are welded by moving a laser beam relative to the sheet material while radiating the laser beam to the shifted surface side of the one side surfaces along the butted line. In the welding method, the whole of the laser beam are radiated on the thick sheet side, and the welding speed is varied during the welding operation. COPYRIGHT: (C)2006,JPO&NCIPI
