Problems solved by technology

In the existing method, the measurement data is used to fit the channel dredging base surface through the multi-level superposition method, which is complex, time-consuming and labor-intensive to operate, and directly and simply connected into continuous broken lines to form the channel dredging base surface, which affects the calculation accuracy and needs to be further optimized.
At the same time, there is no visual and intuitive means for the dredging volume and dredging effect to allow users to see the dredging construction effect

Embodiment Construction

[0013] The following combination figure 1 The technical solution of the claims of the present invention shall be explained.

[0014] S101, using Skyline software to visualize and store the three-dimensional data of river topography;

[0015] Store the XYZ and coordinate reference information in the digital elevation model data (DEM for short) of the existing river channel into the spatial database (PostgreSQL); at the same time, import the DEM directly into the Skyline desktop software as an elevation layer object, and the Skyline software can automatically import it It is resolved into X, Y, Z, and manifested as river topography undulations. With the satellite image of the river, the three-dimensional visualization of the river is realized. This step is the basis for the calculation of dredging engineering; this step obtains the initial terrain M2 visualization three-dimensional data (graphics) of the river;

[0016] S102, completing the calculation of the dredging engineeri...

Abstract

The invention discloses a method for calculating channel dredging engineering construction amount based on Skyline software. The method comprises the following steps: visualizing three-dimensional data of the river terrain by utilizing Skyline software; completing dredging engineering quantity calculation in the Skyline software; and generating a dredging slope model. Through three-dimensional geographic information system software, the dredging engineering mainly relates to three-dimensional visualization of objects. The original complex earth volume calculation of the dredging engineering isrefined and accurate.

Description

technical field [0001] The invention belongs to the engineering design technology, and in particular relates to a technology for determining the construction quantity of a waterway dredging project based on Skyline software. Background technique [0002] In the design of dredging engineering, in order to maintain the stability of both sides of the trench, it is necessary to determine a certain slope slope, that is, the slope of the trench, according to the soil mechanical properties and hydrodynamic conditions of the sediment. Determine the calculated overwidth and calculated overdepth according to the type of dredger. The excavation section is generally designed as an inverted trapezoid, the bottom of the inverted trapezoid is the design excavation width, and the difference between the existing water depth and the design water depth is the design excavation depth. In the previous dredging engineering design, the determination of the center line of the excavation, the size ...
