Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0035] Such as figure 1 Shown: the present embodiment discloses a kind of method based on cubic interpolation drawing dam contour:

[0036] The geometric model of the typical section of the dam is established through CAD software. The typical section includes the selected representative monitoring sections of the dam along the river and across the river. Import it into Hypermesh to establish a finite element model of a large typical section and perform grid division. Export the grid node numbers and corresponding coordinate information of typical sections;

[0037] Preferably, the grid node number and corresponding coordinate information of the typical section are exported and saved as .cor an...

Abstract

The invention discloses a method for drawing a dam contour line based on a cubic interpolation method, which comprises the following steps of: selecting sections of a dam along a river direction and atransverse river direction as typical sections for measuring point prediction, establishing a finite element model of the dam in Hypermesh, performing grid division, and exporting grid node numbers and corresponding coordinate information of the typical sections; reading known measuring point coordinate information and measuring point measuring values of corresponding coordinates in a dam monitoring cloud platform database; based on a support vector machine algorithm, with the known measuring point coordinate information read from the dam monitoring cloud platform database as an independent variable and the measuring point measured value of the corresponding coordinate read from the dam monitoring cloud platform database as a target variable, performing nonlinear training; importing the parameters into the trained model, and solving predicted values of the corresponding nodes; drawing a monitoring point measured value contour line; and visualizing the drawn contour map.

Description

technical field [0001] The invention relates to the field of development and research of a dam monitoring cloud platform, in particular to a method for drawing dam contours based on a cubic interpolation method. Background technique [0002] As an important part of a water conservancy project, a dam plays a huge engineering role in regulating the temporal and spatial distribution of water resources, and plays a very important role in national economic and social development. As a hydraulic structure, the dam not only bears the long-term effects of external loads but also is affected by the surrounding geological structures during long-term operation. There are certain risks in its operation. Dam safety monitoring is an effective means for people to understand the operation behavior and safety status of the dam, and it is also an important non-engineering measure to ensure the safe operation of the dam. In order to grasp the operation status of the dam in time and understand...
