Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deep foundation pit engineering construction, and in particular relates to a deep foundation pit excavation column pile heave monitoring method. BACKGROUND

[0002] At present, in the deep foundation pit engineering construction process, the control of column pile heave is a key link to ensure construction safety. For the monitoring of traditional structure column settlement, usually only two data of cumulative value and daily change are provided, and the data is presented in the form of static data report. However, this way cannot directly provide detailed differential settlement information, so that the data presentation method is not intuitive enough, and there is great limitation in timely finding, analyzing and judging potential safety hazards, which is embodied in the following points:

[0003] 1. Single data display form: The existing column pile monitoring data is usually presented in the form of static table, which lacks dynamic and intuitive display. This single data display form makes it difficult for management personnel to quickly and intuitively understand the spatial distribution and change of column piles in the foundation pit, affecting the decision-making efficiency and real-time monitoring.

[0004] 2. Lack of intuitive comparison ability: The position and deformation of column piles in the foundation pit have complex spatial laws, and the traditional table data cannot effectively show these laws. The lack of intuitive comparison ability makes it difficult for management personnel to accurately understand the state change of column piles in different time periods, thereby affecting the assessment of engineering safety and stability.

[0005] 3. Fixed monitoring point limitation: Column pile monitoring usually relies on a small number of fixed monitoring points, which cannot comprehensively cover the overall behavior of column piles in the foundation pit. The use of fixed monitoring points is prone to the emergence of monitoring blind spots, especially in the complex environment inside the foundation pit, which affects the comprehensiveness and accuracy of the monitoring data.

[0006] 4. Cannot realize the linkage monitoring of column piles and underground continuous walls: In the deep foundation pit excavation process, the deformation of column piles is often closely related to the surrounding supporting structures (such as continuous walls). The existing monitoring report form usually only focuses on the settlement and displacement of column piles itself, ignoring the linkage deformation problem with the surrounding structures such as continuous walls. Due to the lack of comprehensive monitoring of the interaction between column piles and continuous walls, it is difficult to effectively show the synchronous or differential deformation of the two in space.

[0007] In view of the deficiencies in the prior art that the monitoring results of column pile heave in deep foundation pit engineering are presented in the form of static data table, the technical personnel in the field have been seeking a solution. SUMMARY

[0075] Please refer to Figures 1 to 8 , the monitoring method of the deep foundation pit excavation column pile uplift includes the following steps:

[0076] First, please refer to Figures 1 to 7 , execute step S1, construct a three-dimensional display diagram of the column pile and the underground continuous wall top uplift in the foundation pit based on Matlab software.

[0077] Among them, step S1 includes the following sub-steps:

[0078] S11, please refer to Figure 1 , define the outer boundary of the foundation pit: according to the position and geometric shape of the underground continuous wall in the foundation pit, set the plane coordinates of each corner point, and the closed plane of the underground continuous wall composed of each corner point is defined as the outer boundary of the foundation pit; in S11, the closed plane of the underground continuous wall is represented by a set of continuous coordinate points as follows:

Specifically, the first point is connected with the last point to form a closed loop, so as to highlight the outline of the foundation pit in the three-dimensional display.

[0080] S12, define the column pile uplift measuring point and the underground continuous wall top uplift measuring point, and determine the real-time three-dimensional coordinates of each measuring point:

[0081] According to the engineering planning or monitoring requirements, set M column pile uplift measuring points and N underground continuous wall top uplift measuring points;

[0082] According to the position of each measuring point, determine the x-axis coordinate and y-axis coordinate of each measuring point;

[0083] According to the monitoring data of each measuring point provided by the monitoring unit every day, update the z-axis coordinate of each measuring point in real time.

[0084] The real-time three-dimensional coordinates of these measuring points serve as the basic data for subsequent interpolation and three-dimensional display, reflecting the uplift state of the column piles and underground continuous walls in the foundation pit.

[0085] S13、please refer to Figure 2 and Figure 3 Data visualization: the real-time three-dimensional coordinates of each measuring point are visualized; S13 includes the following sub-steps:

[0086] S131, three-dimensional scatter plot: based on the scatter3 function of MATLAB, the real-time three-dimensional coordinates of each measuring point are plotted, so that the real-time three-dimensional coordinates (x, y, z) of each measuring point are displayed in three-dimensional space;

[0087] S132、please refer to Figure 2 and Figure 3 Color differentiation: different colors are assigned to column pile uplift measuring points and underground continuous wall top uplift measuring points, respectively, to identify the positions of different measuring points in three-dimensional space and the corresponding uplift values (i.e., corresponding z-axis coordinate values) through color recognition.

[0088] In order to distinguish between different types of measuring points (i.e., whether they belong to column pile uplift measuring points or underground continuous wall top uplift measuring points), different colors are used for identification; in this embodiment, the measuring points of column pile uplift are represented by red color, and the measuring points of underground continuous wall uplift are represented by yellow color. Through color differentiation, the positions of different measuring points and the corresponding uplift values are intuitively displayed.

[0089] S14, foundation pit grid division: based on the outer boundary of the foundation pit (i.e., the outer contour of the foundation pit) determined in S11, the grid range is determined and the grid is divided; S14 includes the following sub-steps:

[0090] S141, determine the grid range of the foundation pit area: determine the boundary of the grid based on the minimum x-axis coordinate, maximum x-axis coordinate, minimum y-axis coordinate and maximum y-axis coordinate of the outer boundary of the foundation pit; in S141, the boundary of the grid of the foundation pit area is determined using the formula as follows:

[0091] min_x = min(plane_points(:,1));

[0092] max_x = max(plane_points(:,1));

[0093] min_y = min(plane_points(:,2));

[0094] max_y = max(plane_points(:,2)).

[0095] These minimum and maximum values determine the grid range, and the grid will be divided within this range.

[0096] S142, divide the grid according to the set resolution. Specifically, dividing the grid according to the set resolution includes the following steps:

[0097] The division range of the grid is set as:

[0098] x = linspace(min_x, max_x, grid_size);

[0099] y = linspace(min_y, max_y, grid_size);

[0100] where grid_size represents the size of the generated grid, i.e. the number of grids;

[0101] Based on the meshgrid function, a two-dimensional grid coordinate system is generated:

[0102] [X, Y] = meshgrid(x, y);

[0103] where [X, Y] contains the x-axis and y-axis coordinates of each grid point in the entire foundation pit area.

[0104] Specifically, in a two-dimensional plane, a regular grid is divided by uniform spacing. The meshgrid function is used to generate a regular grid, and the spacing of the grid points determines the resolution of the fitted surface. Generally, smaller spacing can provide more detailed results, but it will also increase the amount of calculation.

[0105] S15, please refer to Figure 4 Surface fitting: using interpolation technology to fit the real-time three-dimensional coordinates of each measurement point determined in S12.

[0106] In order to generate a smooth three-dimensional surface from discrete measurement points, interpolation technology is used for surface fitting. Specifically, through the existing measurement point data (i.e. the real-time three-dimensional coordinates obtained in S12), a high-order polynomial is constructed to accurately fit the data points and ensure smooth transition between interpolation points. Through this method, a smooth and continuous distribution surface is generated to describe the distribution of the uplift of the column pile and the underground continuous wall in the plane.

[0107] S15 includes the following sub-steps:

[0108] Surface fitting is performed based on the following formula: where λ i (x, y) is the interpolation function, z i is the uplift value of the known measurement point;

[0109] Based on the griddata function, interpolation is performed according to the existing measured point data, and is expressed by the following formula: Z = griddata(xdata, ydata, zdata, X, Y, 'cubic').

[0110] Preferably, refer to Figure 5 S15 further comprises the following steps:

[0111] In MATLAB, based on the contour function, the contour lines are superimposed on the three-dimensional surface after surface fitting to show different height levels of the upheaval; wherein the contour lines are expressed by the following formula: f(x, y) = z0; wherein z0 is a certain height, and the function value is the contour line corresponding to the height.

[0112] S16, refer to Figure 6 Result display: the results of surface fitting are displayed. Specifically, the text function is used to mark the data of each measured point in the surface fitting results.

[0113] In order to improve the readability of the graph, especially for some key data points, the application provides a data labeling function. Specifically, by using the text function in MATLAB, a text label is added to the position of each measurement point to mark its corresponding height value (i.e. z-axis coordinate).

[0114] Then, step S2 is performed to monitor the upheaval of the column pile and the underground continuous wall based on the constructed three-dimensional display graph.

[0115] Based on the constructed three-dimensional display graph, the upheaval distribution of the column pile and the underground continuous wall can be intuitively displayed. This method not only effectively reflects the position and quantity of the upheaval, but also helps project managers quickly identify areas with large and small upheaval amounts, providing important guidance and decision support for safe construction.

[0116] It should be noted that, for the foregoing method embodiments, in order to simply describe, they are all expressed as a series of action combinations, but those skilled in the art should know that the application is not limited by the described action sequence, because according to the application, certain steps can be performed in other order or simultaneously. Secondly, those skilled in the art should know that the embodiments described in the specification all belong to preferred embodiments, and the actions and modules involved are not necessarily required by the application.

[0117] In the above embodiments, the description of each embodiment has its own focus, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0118] The application has the following advantages:

[0119] 1) Comprehensive information integration display: The monitoring method of the present application introduces a three-dimensional display method, which can more comprehensively and intuitively display the heave of column piles and underground continuous walls, making the monitoring more efficient and accurate.

[0120] 2) Quickly identify problem areas: The three-dimensional display graph can help project managers quickly identify areas with large or abnormal column pile heave, which may have safety hazards or require special attention. By discovering problems in a timely manner and taking appropriate measures, engineering risks can be effectively reduced.

[0121] 3) Make up for the lack of fixed monitoring points: Through surface fitting method, the spatial distribution of column pile heave and underground continuous wall heave in the foundation pit is comprehensively displayed, overcoming the problem of incomplete data or blind spots caused by fixed monitoring points in traditional monitoring methods, improving the comprehensiveness and accuracy of monitoring.

[0122] 4) Column pile and underground continuous wall linkage analysis: The three-dimensional display graph simultaneously displays the heave of column piles and underground continuous wall in the foundation pit, realizing the linkage monitoring and analysis between column piles and underground continuous walls, helping project managers better understand the mutual influence between the two, providing more accurate decision-making basis to ensure the overall safety and stability of the foundation pit.
