Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of soil moisture content monitoring, especially relates to a self-advancing soil moisture content monitoring device. BACKGROUND

[0002] In the practice of slope stability monitoring and early warning, accurately determining soil moisture content is crucial. Soil moisture content directly affects the mechanical properties of soil. High moisture content increases the bulk density of the soil while reducing its strength, which in turn affects the stability of the slope and increases the risk of slope instability.

[0003] Currently, the main methods for monitoring soil moisture content for slope early warning are resistivity method, frequency domain reflectance (FDR) method, time domain reflectance (TDR) method, and optical method. In recent years, the frequency domain reflectance (FDR) method has made rapid progress. FDR sensors are based on dielectric theory and use the propagation characteristics of electromagnetic waves at different frequencies in soil to measure. When the soil moisture content changes, its dielectric constant will change, affecting the propagation speed and reflection of electromagnetic waves. By measuring these changes, the volumetric water content of the soil can be calculated.
