The invention discloses a high slope monitoring method. The method comprises the steps: establishing monitoring points in a project construction area range; arranging more than three level datum points at different heights in a project construction area range to form a vertical displacement monitoring network, and arranging more than three plane datum points in the project construction area rangeby taking the construction plane coordinate system as a reference to form a plane displacement monitoring network; adopting a precise total station with nominal precision, performing observation according to precise triangulation height measurement, and obtaining the settlement change of each deformation observation point through periodic observation of each point; adopting a precise total stationwith nominal precision, observing a horizontal displacement mark buried in a side slope according to a free observation station method or a polar coordinate method, and obtaining the horizontal displacement change of each deformation observation point through periodic observation of each point. According to the vertical and horizontal change data, the overall change trend of the slope is visualized and quantified in combination with a three-dimensional model; the settlement change and the horizontal displacement change of each base point of the side slope can be measured, so the characteristics of the side slope are comprehensively understood, and an instructive effect is achieved for formulating a reasonable and effective scheme for side slope construction.
Description
technical field [0001] The invention relates to the field of slope construction, in particular to a method for monitoring high slopes and slopes. Background technique [0002] The side slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. In road construction, in order to ensure the construction progress, it is necessary to monitor the slope, so as to facilitate the understanding of the geological characteristics of the slope, and the corresponding construction can be carried out according to the geological characteristics to ensure the construction efficiency and construction quality, but the current slope monitoring method cannot Comprehensive detection and understanding of slopes, especially for monitoring high slopes, which can easily affect slope construction. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a high side slope mon...
