The invention belongs to the technical field of slope engineering monitoring, and discloses a system and a method for monitoring anchoring force of a plant root system to slope rock soil. A distributed optical fiber sensing module acquires strain information of the slope rock soil of a layer where the plant root system is located; a distribution demodulator is used for calculating the wavelength of the sensing optical fiber according to the strain information of the slope rock soil of the layer where the plant root system is located to obtain wavelength change information; a data processor obtains stress-strain data of slope rock soil of the layer where the plant root system is located and anchoring force data of the plant root system to the slope rock soil according to the wavelength change information; and a computer management system forms a slope plant type selection database according to the stress-strain data of the slope rock soil of the layer where the plant root system is located, the anchoring force data of the plant root system to the slope rock soil, the slope parameter information and the climate parameter information. According to the method, the reinforcing effect ofthe plants on the slope rock soil can be visually evaluated, and a scientific and reasonable basis can be provided for model selection of the slope plants.
Description
technical field [0001] The invention relates to the technical field of slope engineering monitoring, in particular to a system and method for monitoring the anchoring force of plant roots to rock and soil on slopes. Background technique [0002] Vegetation slope protection technology is a slope protection technology that uses the basic knowledge of engineering mechanics, soil science, ecology and botany to support the slope to form a comprehensive slope protection system composed of plants or engineering and plants. Plants are a technology for improving slope water and soil loss, slope instability and other problems. Plant slope protection can purify the air, beautify the environment, and have low follow-up support costs, which are not available in traditional slope support technologies such as shotcrete and bolt support. In slope engineering, because there are many types of plants suitable for ecological slope protection, there are differences in the root system characteri...
