The invention proposes a method for measuring the stability of armor blocks based on acceleration sensors, which belongs to the field of physical model tests of breakwaters. The measurement facilities and instruments include water tanks, breakwater model sections, armor block models, acceleration sensors and power supply equipment. Its characteristics Yes: When there is no model in the tank, continuously adjust the wave elements until a wave file containing the required wave elements is obtained. After obtaining all the required wave-making files, install the breakwater section model in the tank, and then place the armor block model. The armor block model includes a model with a built-in acceleration sensor and a model without an acceleration sensor. The effect is that the wave acts on the armor block The body causes small vibration or large movement of the block, and the sensor generates induction to make the data fluctuate, so as to judge the movement of the block.
Description
technical field [0001] The invention relates to the technical field of wave physical model tests, in particular to a method for measuring the stability of a face armor block based on an acceleration sensor. Background technique [0002] Physical model test is an important means to explore the stability of armor blocks. Except for projects with small wave heights and small engineering quantities or when there are test data under similar conditions, the research on block stability generally requires block stability tests. At present, the amount of vibration of the block in the test cannot be judged manually, the artificial measurement of the amount of motion of the block is time-consuming and laborious, and the judgment of the stability of the block has a large human error. Although there is a method of laser or infrared scanning to compare the planar imaging of block stones, it is relatively general and the equipment is expensive. Contents of the invention [0003] The te...
