Problems solved by technology

The static leveling system can directly obtain the differential settlement of each monitoring point. If it is necessary to obtain the absolute settlement of each measuring point, it is necessary to establish a stable working base point. Large-area filling sites, large-scale landslides, underground mined-out areas, etc., it is difficult to build the working base point in

Abstract

The invention discloses a satellite positioning and static leveling-based layered settlement monitoring system and method. The system comprises a base station, a monitoring station which is arranged in a settlement monitoring area and a monitoring center which communicates with the monitoring station, wherein the base station communicates with the monitoring station; the monitoring station comprises an observation pillar, a second Beidou satellite signal receiver mounted on the observation pillar, a data transmission unit, a plurality of layered settlement marks and a static level system; the static level system comprises a plurality of static level gauges; each layered settlement mark is provided with one static level gauge; one of the static level gauges is arranged on the observation pillar. The method comprises the following steps: I, setting of the monitoring system; II, data acquisition and transmission; III, data processing and analysis. According to the satellite positioning and static leveling-based layered settlement monitoring system and method, the calibration and correction problems of the instable working base points during the static leveling can be effectively solved, and the long-term, remote and real-time monitoring for the layered settlement deformation of the geologic bodies can be realized.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering monitoring, and in particular relates to a layered settlement monitoring system and method based on satellite positioning and static leveling. Background technique [0002] In highways, railways, airports, docks, dams and other projects, in order to grasp the effective compression layer thickness of the foundation soil and the deformation characteristics of each layer of soil within the compression layer range, study the development law and stability of foundation deformation, and carry out engineering safety warnings, etc. , it is often necessary to monitor the layered settlement of the soil. [0003] At present, there are mainly two monitoring methods commonly used in engineering for soil layer settlement: First, the electromagnetic settlement method: the casing is buried vertically at the monitoring position in the stratum of the monitoring site, and the outer wall of the casin...
