Title:
DEVICE FOR TESTING TANGENTIAL AND NORMAL RESISTANCE OF ANCHOR CHAIN TO SOIL UNDER EQUIVALENT ELASTIC BOUNDARY
Document Type and Number:
WIPO Patent Application WO/2020/057396
Kind Code:
A1
Abstract:
A device and method for testing the tangential and normal resistance of an anchor chain to soil under an equivalent elastic boundary. The device comprises a support frame, a transmission device (4), a pneumatic loading system, a test box (5), a vertical displacement applying portion (6), a tangential anchor chain unit (7), a normal anchor chain unit (8) and the like. By means of using springs (20) of equal stiffness to simulate an elastic boundary, the size of the test box (5) may be greatly reduced under the effect of overcoming boundary conditions, which may effectively save materials and reduce the difficulty of experimental operations. At the same time, the present invention integrates normal and tangential resistance tests into one body, and may simultaneously measure the tangential and normal interactions between the anchor chain and the soil. Important design parameters may be provided for the calculation of a soil section of an engineering anchor chain, which has important referential significance for the design of an anchoring system in which an anchor point is below a seabed mud surface.
