Description

Technical Field

[0001] The invention relates to the technical field of rock slope disaster early warning, and in particular to a micro-core pile inclination angle early warning method. Background Art

[0002] With the continuous development of underground space, the original stable soil and rock formation environment has gradually changed, resulting in the gradual generation of loose, hollow and other unfavorable geological bodies in the underground soil layer. Due to long-term interference from external factors, these underground hidden patients continue to develop upward and eventually develop to the ground, and then form ground collapse. Sudden surface collapse poses a huge threat to people’s life and property safety and production and life, and also causes great damage to engineering structures and the natural environment;

[0003] The traditional "early warning mechanism" is: when the inclination value of the micro-core pile exceeds the threshold, an early warning message is generated. However, this early warning mechanism has the following problems:

[0004] First, after the warning, the subsequent changes in the inclination of the micro-core pile cannot automatically continue to warn, and manual intervention is required to reset the inclination value to zero before continuing the warning. For example, when the inclination is 2°, a warning message is generated. After the warning, the inclination continues to increase to 4°, and no new warning is generated. At this time, the inclination of 2° needs to be manually reset to zero. When the inclination continues to change by 2°, a warning message is generated.

[0005] Second, in the actual process, the inclination angle has a direction, and the traditional "early warning mechanism" does not consider the direction, resulting in early warning errors. For example, the inclination angle in the first state is 1.5°, and the direction is due north; the inclination angle in the first state is 1.5°, and the direction is due south. From the first state to the second state, although the inclination angle value has not changed, the direction has changed, so the inclination angle has actually changed by 3°. At this time, it is necessary to generate early warning information, but the traditional "early warning mechanism" does not generate early warning information. Summary of the invention

[0006] In view of this, the problem to be solved by the present invention is to provide a micro-core pile inclination angle early warning method.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A micro-core pile inclination angle early warning method, comprising:

[0009] S1, fixing a micro-core pile on the landslide body, measuring the tilt state parameters in the initial state by the micro-core pile, and determining the initial state vector A;

[0010] S2, measuring the tilt state parameters in the current state and determining the current state vector B;

[0011] S3, determining a vector change value Δ according to the initial state vector A and the current state vector B;

[0012] S4, calculating the modulus length |Δ| of the vector change value Δ;

[0013] S5, determine whether the modulus length |Δ| of the vector change value Δ is greater than a threshold; if so, execute step S6; if not, execute step S7;

[0014] S6, issue a warning message, reset the current state vector B to the basic state vector C, and execute step S2;

[0015] S7. No warning information is issued.

[0016] In the present invention, the tilt state parameters in the initial state include the tilt angle θ1 and the inclination σ1;

[0017] The inclination angle θ1 represents the inclination angle of the landslide body in the initial state;

[0018] The inclination σ1 represents the direction of the inclination angle of the landslide body in the initial state;

[0019] The tilt state parameters in the current state include the tilt angle θ2 and the inclination σ2;

[0020] The inclination angle θ2 represents the inclination angle of the landslide body in the current state;

[0021] The inclination σ2 represents the direction of the inclination angle of the landslide body in the current state.

[0022] In the present invention, step S1 specifically includes:

[0023] According to the formula A=(θ1cosσ1,θ1sinσ1), the initial state vector A is determined and the initial state vector A is expressed in coordinate form.

[0024] In the present invention, step S2 specifically includes:

[0025] According to the formula B = (θ2cosσ2, θ2sinσ2), the initial state vector B is determined and expressed in coordinate form.

[0026] In the present invention, step S3 specifically includes:

[0027] According to the formula Δ=BA=(θ2cosσ2-θ1cosσ1,θ2sinσ2-θ1sinσ1), the vector change value Δ is determined.

[0028] In the present invention, step S4 specifically includes:

[0029] According to the formula Determine the modulus length |Δ|.

[0030] The advantages and positive effects of the present invention are:

[0031] In the present invention, the micro-core pile can determine the inclination degree of the landslide body by monitoring the inclination angle and tendency of the landslide body, analyze the stability change trend of the landslide body through the inclination change of the landslide body, and then give an early warning of the safety status of the landslide body;

[0032] Furthermore, when determining the inclination of the landslide body, the inclination change and the inclination change of the landslide body are comprehensively considered. That is to say, on the basis of the prior art, the inclination factor is additionally considered. Therefore, the problem that the inclination factor is not considered in the prior art and the warning information is not generated even if the inclination angle changes is avoided, the present invention has the characteristics of comprehensive consideration of factors and being more in line with the actual situation.

[0033] In addition, the present invention also has a continuous early warning function, which avoids the problem in the prior art that manual intervention is required to reset the inclination angle of the micro-core pile to zero before continuing to warn, improves the flexibility of the design, and has strong practicality.

[0042] The inclination angle θ1 represents the inclination angle of the landslide body in the initial state;

[0043] The inclination σ1 represents the direction of the inclination angle of the landslide body in the initial state.

[0044] Specifically, according to the formula A=(θ1cosσ1,θ1sinσ1), the initial state vector A is determined, and the initial state vector A is expressed in coordinate form.
