The system comprises a satellite positioning assembly, a monitoring assembly and measuring assemblies; the satellite positioning assembly is arranged on a standard reference point; the monitoring assembly is arranged on a measurement reference point; the measuring assemblies are respectively arranged on multiple observation points; the satellite positioning assembly is used for receiving a satellite signal, and obtaining a first elevation value of the measurement reference point relative to the standard reference point based on the satellite signal; the monitoring assembly comprises a first metering device used for obtaining a first elevation difference value;the measurement assembly comprises a second metering device used for obtaining a second elevation difference value; and the system further comprises control equipment used for obtaining the first elevation value, the first elevation difference value and the second elevation difference value, and determining the deformation degree of a soil layer area corresponding to the observation point based onthe first elevation value, the first elevation difference value and the second elevation difference value.

Description

technical field [0001] The present application relates to the technical field of geotechnical engineering detection, in particular to a monitoring system, method and storage medium for deformation monitoring of bridge pier abutments. Background technique [0002] The traditional monitoring of bridge pier settlement and inclination angle is through the manual use of optical instruments, including the use of levels, theodolites and total stations, etc., and referring to the reference point near the bridge (generally only about 200m away from the bridge), to measure the deformation relative to the reference point. Then calculate and measure the settlement and inclination angle of the pier and abutment. [0003] This method is relatively primitive. In areas with deep soil layers, the reference point is often affected by various artificial activities such as pumping and excavation of foundation pits due to the limited burial depth (traditional instruments generally cannot penetra...

Problems solved by technology

[0003] This method is relatively primitive. In areas with deep soil layers, the reference point is often affected by various artificial activities such as pumping and excavation of foundation pits due to the limited burial depth (traditional instruments generally cannot penetrate compressed soil layers more than 100 meters thick). In long-term monitoring, the soil layer where the reference point is located (that is, the loose compressed layer) will still produce slight settlement, which cannot guarantee the absolute stability of the reference point, resulting in overall measurement errors, making it difficult to guarantee the measurement accuracy, and cannot meet the high-standard millimeter-level accuracy Requirements, and manual observation has the problems of operational error, high labor intensity and low efficiency
