The slope displacement and inclination angle monitoring device includes hydraulic type sedimentation detection and inclination angle detection integrated monitoring instruments, benchmark liquid level tanks, a data sampler, a laser rangefinder and a data acquisition controller. The invention also discloses a slope displacement and inclination angle monitoring method. According to the method, a plurality of contour lines are selected on a measured slope, and a plurality of hydraulic type sedimentation detection and inclination angle detection integrated monitoring instruments are distributed on the contour lines; the laser rangefinder is installed on the opposite side of the measured slope; the hydraulic type sedimentation detection and inclination angle detection integrated monitoring instruments are adopted to monitor the vertical displacement amount and inclination angle change amount of the measured slope; the laser rangefinder is adopted to measure the horizontal displacement amount of the measured slope; the overall displacement and inclination angle data of the measured slope are obtained; and various kinds of slope analysis models are used auxiliarily, and therefore, an effective means can be provided for landslide disaster prevention.

Description

technical field [0001] The invention relates to an instrument and a monitoring method for slope monitoring. Background technique [0002] In the field of slope monitoring, manual monitoring is common, that is, monitoring personnel look for cracks on the measured slope and measure their changes, which is a huge workload and unsafe. When encountering bad weather conditions, it is even impossible to work. [0003] There is also a method of using a pull-type displacement sensor to monitor the displacement between cracks or adjacent fixed piles, or using an inclinometer to monitor the slope change of the slope; there is also a method of using a laser rangefinder to measure the fixed single-point displacement of the measured slope Methods. [0004] However, monitoring cracks or the displacement between adjacent fixed piles, as well as the displacement of a fixed single point cannot accurately reflect the overall horizontal and vertical changes of the measured slope, as well as t...

Problems solved by technology

[0004] However, monitoring cracks or the displacement between adjacent fixed piles, as well as the displacement of a fixed single point cannot accurately reflect the overall horizontal and vertical changes of the measured slope, as well as the change of inclination angle, so it cannot be used for various types of slopes. Predictive mathematical models provide accurate underlying data
