The invention discloses a multifunctional displacement meter for a model test and a displacement measurement method, which belong to the technical field of displacement monitoring in civil engineering. The multifunctional displacement meter comprises a model box, a displacement measuring part and a displacement meter main part. Test time is set on a controller according to a test period, and the controller controls an electric telescopic rod to extend and retract and simultaneously controls a laser switch in the displacement meter main part, thereby realizing displacement measurement in an automatic grading loading process. A vernier caliper is fixed at the two ends of the top of the model box, and a loading device can freely slide on the vernier caliper, so that the displacement meter cancontinuously and horizontally move without disassembling and assembling a plurality of bolts. The device is ingenious in structural design, easy to operate and high in controllability, the whole testprocess can be clearly and accurately reflected, and the displacement measurement efficiency can be remarkably improved.
Description
technical field [0001] The invention belongs to the technical field of displacement monitoring in civil engineering, and relates to a multifunctional displacement meter used in model tests and a displacement measurement method. Background technique [0002] Slope landslides, weathering spalling, roadbed settlements caused by rainfall and earthquakes, and land subsidence caused by massive surcharges or over-exploitation of groundwater can all cause horizontal or vertical displacement of the soil. With the development of science and technology, the field of civil engineering has developed rapidly, especially in the field of geotechnical engineering. Important progress has also been made in slope protection, roadbed water damage prevention, and stratum subsidence, such as anchor support, reinforced retaining walls, The emergence and maturation of methods such as foundation and foundation reinforcement and protection provide powerful methods and theoretical support for slope sta...
