The inclinometer is an instrument used to measure the apex angle and azimuth of engineering structures such as boreholes, foundation pits, foundation foundations, walls and dam slopes.
An inclinometer is an in-situ monitoring instrument that measures the inclination and azimuth of a borehole. In foreign countries, in the 1950s, the inclinometer was used to monitor the geotechnical engineering of earth-rock dams, roadbeds, slopes and tunnels in situ. Since the 1980s, China has introduced the inclinometers produced in the United States, Japan, and the United Kingdom to conduct in-situ monitoring of some major geotechnical projects, and achieved good results. Some related research institutions subsequently developed intelligent inclinometers such as resistance strain gauges, accelerometers, and electronic gauges. So far, various inclinometers have been widely used in the fields of water conservancy and hydropower, mineral metallurgy, transportation and urban construction, and have played an important role in ensuring the design, construction and safety of geotechnical engineering.
