Problems solved by technology
The above-mentioned indoor slope model displacement test technology has the following deficiencies: 1. The number of strain gauges that can be arranged for displacement monitoring is limited, and for indoor slope model tests, the operation process when arranging strain gauges is too cumbersome; The displacement change of the slope is limited, and often can only represent the local displacement, and cannot clearly reflect the overall displacement and deformation of the slope; 3. Since the strain gauge needs to be used in conjunction with the sensor, this greatly increases the preparatory test. 4. For indoor slope model tests, the arrangement of strain gauges will also affect the overall stability of the model, which is prone to certain experimental errors

The invention discloses a non-contact indoor slope model displacement monitoring method. The non-contact indoor slope model displacement monitoring method comprises the steps of firstly, casting a slope model in a layered way in an indoor slope model test system; secondly, arranging a black point with a diameter about 2 millimeters on an observation surface of a to-be-loaded indoor slope model, and taking the black point as a displacement monitoring point; thirdly, recording a test process by shooting of a high-speed camera; fourthly, performing binarization processing on pictures shot by thehigh-speed camera; and fifthly, capturing each displacement monitoring point according to information of a pixel grey value, and acquiring displacement change condition of each displacement monitoringpoint to form a displacement vector graph. An existing contact-type displacement monitoring technical method and test means is substituted, the integral displacement and change condition of the indoor slope model is clearly and completely acquired under a non-contact condition, and the non-contact indoor slope model displacement monitoring method has the advantages of high accuracy and the like and is simple and easy to operate.
Description
technical field [0001] The invention belongs to the technical field of geological disaster prevention and control, and relates to an indoor slope model monitoring method, in particular to a non-contact indoor slope model displacement monitoring method. Background technique [0002] my country is a country with frequent mountain hazards, especially slope hazards, so the research on slope hazards has become a widely concerned issue. At present, the existing indoor slope displacement monitoring technology is to arrange strain gauges inside the slope, and at the same time, it needs to be used together with sensors to monitor the displacement and deformation of the slope. The above-mentioned indoor slope model displacement test technology has the following deficiencies: 1. The number of strain gauges that can be arranged for displacement monitoring is limited, and for indoor slope model tests, the operation process when arranging strain gauges is too cumbersome; The displacement...
