[0002] With the increasing number of water conservancy project construction projects, people are paying more and more attention to water conservancy project construction. As an indispensable building in water conservancy project construction, dam slope has received widespread attention. Usually, after the construction of dam slope project is completed, it is necessary to conduct steady-state detection. By analyzing its steady state, we can timely understand the existing defects, which can not only reduce the occurrence of safety problems, but also prevent potential problems and take measures in advance.

[0003] However, most of the current slope stability detection of dam projects focuses on the surface displacement and depth displacement of the slope. If the surface displacement and depth displacement are not obvious, it means that the slope stability is good and there is no safety hazard. However, it still has some shortcomings in actual use. The detection target is focused on the surface displacement and depth displacement of the slope. This detection method is relatively simple and cannot effectively detect the existing safety hazards. Summary of the invention

[0010] The construction stability coefficient, construction safety factor and slope deformation coefficient are weighted to obtain a comprehensive detection coefficient;

[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0018] In the existing technology, the detection targets are concentrated on the surface displacement and depth displacement of the slope, which is a relatively simple detection method. However, most areas of the dam slope need to be immersed in water for a long time, which will be affected by many factors such as water flow velocity, seepage, foundation bearing capacity, etc., resulting in not only the displacement of the slope, but also cracks in the slope. Therefore, multi-faceted detection of the dam slope can reflect its corresponding comprehensive detection results.

[0019] Please refer to Figure 1 , a dam engineering slope stability detection method, comprising:

In this embodiment, the images of each detection sub-area of ​​the dam slope are captured in real time through artificial intelligence machine vision technology, and the captured images are processed using image processing algorithms to accurately calculate the displacement status of each detection sub-area of ​​the target dam slope. For example, calibration markers are set in the dam slope area, and the motion trajectory of the corresponding markers is identified through image processing technology, thereby obtaining the motion trajectory of the landslide body.

The data is integrated and calculated by computer to quickly obtain the slope gradient, which is recorded as θ. Similarly, the width d and depth h of the slope crack can be obtained. By placing a flow meter in the monitoring sub-area, the water flow velocity in the monitoring sub-area per unit time can be obtained, which is recorded as V. i .

When the groundwater level rises, the shear strength of the slope decreases, which easily leads to slope instability. On the contrary, when the groundwater level drops, the shear strength of the slope increases, which is conducive to the stability of the slope. ζ represents the construction stability coefficient. The larger the soil foundation bearing index, the smaller the displacement change index, precipitation fluctuation index and groundwater level fluctuation index, the larger the construction stability coefficient, indicating that the dam slope stability is better.

The product of the slope width and the slope depth represents the area of ​​the slope crack. i The sum and average operation of represents the average water flow velocity of the dam slope in the target area; η represents the slope deformation coefficient. The larger the area of ​​the crack, the greater the average water flow velocity, and the larger the slope deformation index, indicating that the slope is more easily deformed.
