Title:
LOAD TEST METHOD AND ANALYSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/210804
Kind Code:
A1
Abstract:
The present invention minimizes the labor and cost required for a load test. A load test method for a steel pipe pile (12), which was installed while removing crushed rock by using a vibrator (13) to cause the steel pipe pile (12) to vibrate in the vertical direction, thereby crushing a bedrock (11), and supplying a jet of water through a hollow section of the steel pipe pile (12) to a tip end section of the steel pipe pile (12), wherein after a support layer is reached, the supply of the jet of water is stopped, and an accelerometer (19) is used to measure the acceleration of the steel pipe pile (12) when the vibrator (13) has been used as a pressurizing device to apply vibrations to the steel pipe pile (12). The measured acceleration is inputted into an analysis system (20). The analysis system (20) calculates the ground resistance of the bedrock (11) according to an unloading point method in which said acceleration is used.
