Abstract

The invention provides a bottom friction coefficient calibration system for a gravity type structure stability test, and belongs to the field of friction coefficient tests. The system is implemented as follows: (1), carrying out pre-measurement preparation; (2), manufacturing a test gravity type structure; (3), grading and sorting rock blocks of a structural foundation cushion layer; (4), throwingand filling rock blocks in a foundation trench and carrying out leveling; (5), erecting and fixing a force measuring assembly; (6), calibrating and debugging a force measuring system; (7), arrangingthe structure on a rock block foundation; (8), connecting the structure and a force measuring system traction rope; (9), measuring tension and calculating a friction coefficient; and (10), comparing the friction coefficient with a standard value, and judging whether the product is qualified; if not, carrying out roughening measure treatment compensation on the bottom of the gravity type structure,repeating work from steps (8) to (10), ending the measuring under the condition of qualification and carrying out a stability test. The system is ingenious in conception and easy to operate, and makes up the influence of different model materials and prototypes caused by reduction of the test scale, so that the test precision is ensured and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of friction coefficient test, and relates to a gravity type structure, that is, a vertical caisson, a block and a retaining wall, and a breakwater or a wharf hydraulic structure of a slope type wave retaining wall. When a laboratory carries out a physical model test of structural stability, In order to ensure the accuracy of the test, the friction coefficient k of the bottom of the gravity structure made in the model test is not less than the static friction coefficient 0.6 required by the design standard, and a series of calibration and verification work of measurement, correction and adjustment measures is carried out, and finally the friction of the bottom of the structure required by the test is obtained. The invention relates to the test simulation technique of the coefficient k, in particular to a system for calibrating the coefficient of friction at the bottom of the gravity structure stability test.
