Title: Method for measuring stress of underground buried pipe
Inventor: OGAWA YASUO
IPC: F17D5/00
Filed: 1993-03-30
Abstract: PURPOSE:To accurately measure the bending stress generated at a buried pipe as in a buried land by considering not only the amount of settlement to be measured but also the amount of horizontal displacement. CONSTITUTION:When a drilling region 3 is drilled for building construction near a pipe 2 buried under a buried ground 1, an amount of horizontal displacement 5 is generated at a proximity part 4 of the buried pipe 2. Bending stress due to settlement in vertical direction is also generated at the buried pipe 2. The true amount of settlement operated on the proximity. part 4 is equal to the sum of an amount of horizontal displacement 5 and the amount of settlement in vertical direction. By measuring the magnetostriction at measurement points 11-15 along the buried pipe 2, the direction of bending at the measurement points 11-15 can be detected. The true amount of ground displacement operated in the bending direction can be obtained according to the location where the amount of settlement is actually measured and the bending direction. A position with the maximum bending stress can be detected by the stress analysis based on the amount of ground displacement.
