METHOD FOR EXECUTION AND LOADING TEST IN MODEL SAND GROUND, DEVICE THEREFOR, AND GROUND CREATING METHOD

摘要

PROBLEM TO BE SOLVED: To reproduce the actual state of execution of a rotary press-in construction method as much as possible, control overburden load acting on the pile head of a model pile at execution, execute loading tests to the model pile in an executed state, and create uniform ground with few artificial variations in a short time.;SOLUTION: The execution and loading tests are performed in the previously created model sand ground 3 by a gravitational force field through the use of the model pile 14. This device for the execution and loading tests in the model sand ground 3 is provided with a means for providing the model pile 14 with a turning force and rotating, pressing in, and passing in the model pile 14 to a predetermined location in the model sand ground 3 only by a thrust generated in the model pile 14 by the turning force, a means for measuring torque and axial forces generated in each of parts A-E of the model pile 14 when the model pile 14 is rotated and pressed in the model sand ground 3, a means for loading a vertical load to the model pile 14 by adding forces to the model pile 14 rotated and pressed in the model sand ground 3, and a means for measuring the resistance characteristics of the model pile 14 generated by the loading of the vertical load when the model pile 14 is pushed in and pulled out of the model sand ground 3.;COPYRIGHT: (C)2002,JPO
