Description

TECHNICAL FIELD

[0001] The utility model relates to landslide monitoring device technical field, concretely is a landslide monitoring device of internal stress and strain monitoring of side slope. BACKGROUND

[0002] Side slope refers to the slope surface with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. In side slope engineering, ensuring the stability of the side slope is the key to preventing geological disasters, protecting infrastructure and ensuring public safety. The stress and strain state inside the side slope directly reflects its stress condition and deformation trend, and is the core parameter for evaluating the stability of the side slope. The traditional side slope monitoring method mainly relies on surface observation and limited borehole testing, which is difficult to comprehensively and real-time capture the complex mechanical behavior and its changes inside the side slope. With the development of sensor technology and data processing capability, modern landslide monitoring devices can integrate multiple high-precision sensors to realize continuous and automatic monitoring of the stress and strain state inside the side slope. These devices not only improve the accuracy and timeliness of the monitoring data, but also provide a more reliable early warning mechanism by combining advanced data analysis algorithms, significantly enhancing the prediction ability and response speed of potential landslide risks.

[0003] In the prior art, the landslide monitoring device is mainly fixedly installed on the side of the highway by inserting the rod into the soil, which effectively monitors the landslide.

When part of the side slope slides, the inclinometer monitors the equipment tilt and shaking, and the alarm reminds the on-site personnel and vehicles to quickly move away, solving the background problem.
