Description

Technical Field

[0002] In the field of foundation construction, when encountering soft foundation, in order to strengthen the foundation, vibratory pile composite foundation is generally used as the solution. The manufacturing process of vibratory pile is generally divided into a hole making process and a vibration compaction process. The hole making process generally uses a vibrator to vibrate downward to form a vibratory hole. The vibration compaction process generally introduces crushed stone in sections, and then vibrates it with a vibrator. The operation is repeated until all vibratory crushed stone piles are formed in the vibratory hole.

[0003] In the quality acceptance link, it is necessary to judge the parameters of the vibro-compacted stone piles and finally determine whether the project is qualified. Among them, the shape, radius, depth, etc. of the vibro-compacted stone piles are all important bases for judgment. In the existing technology, only discrete radius, depth, and gravel weight data are provided for acceptance, and no three-dimensional vibro-compacted stone pile model is provided. This is extremely unfriendly to quality acceptance. In order to provide auxiliary acceptance, a three-dimensional stone pile model is needed to intuitively display the stone pile.

[0048] Example 1

[0049] On the one hand, if Figure 3 As shown, the present invention provides a method for generating a three-dimensional gravel pile based on abnormal current calibration, comprising the following steps:

[0050] S1.

[0051] S2. Obtain the compaction depth-time curve and the crushed stone weight history record of the hole-making section, such as Figure 2 As shown, the X-axis of the compaction depth time curve is time Tm, and the Y-axis is the compaction depth Lm; the depth of each completed vibration compaction is calibrated from the compaction depth time curve to form a vibration compaction depth sampling set SLmt=(Lmt1, Lmt2); the gravel weight corresponding to the depth of each completed vibration compaction is calibrated according to the vibration compaction depth sampling set SLmt=(Lmt1, Lmt2…) and the gravel weight historical record to form a gravel weight sampling set SG(G1, G2,…);

[0052] S3, the crushed stone weight corresponding to the depth of the completed vibration density falling within the range of Lkq-Lkw is grouped into a crushed stone weight set SG for the same stratum group 分 (G 分 1, G 分 2, ...), calculate the gravel weight set SG for each stratum group 分 Total crushed stone weight G;

[0053] S4, obtaining the thickness H of each stratum group by subtracting Lkw and Lkq of the same stratum depth segment, and calculating the radius r of the gravel pile of each stratum group according to the thickness H of each stratum group and the corresponding total gravel weight G;

[0054] S5. Using Lkw and Lkq of each stratigraphic group as Y values ​​and the radius r of the gravel pile of each stratigraphic group as X value, construct two coordinate points on the contour line of each stratigraphic group;

[0055] S6, such as Figure 5 As shown, the contour curve of the gravel pile in the hole-making section is obtained by smooth linear fitting based on the coordinate points of all stratigraphic groups;

[0056] S7. Obtain a three-dimensional model of the gravel pile entity based on the contour curve of the gravel pile in the hole-making section.

[0057] Further, such as Figure 1 , Figure 3 , Figure 4 As shown, according to the pore-forming current time curve and the pore-forming depth time curve, multiple current segments are calibrated based on the current anomaly segmentation and the corresponding formation depth segments are calibrated, which specifically includes the following steps:

[0058] S11, taking the starting point of the pore depth as the reference point, 7 meters as the reference point, taking the end point of the pore depth as the end point, 19.8 meters as the end point, obtaining the pore depth at each interval of a particle scale (0.3 meters), forming a pore depth sampling set SLk=(Lk1, LK2...), which has 44 pore depth elements, obtaining the time corresponding to each pore depth based on the pore depth time curve, that is, finding 44 time from the pore depth time curve according to these pore depths, forming a time sampling set STk(TK1, TK2...), which has 44 time elements, and then obtaining the pore current corresponding to each pore depth based on the corresponding time and the pore current time curve, forming a pore current sampling set SIk=(Ik1, IK2...), which has 44 pore current elements;

[0059] S12, calculate the average value of the pore-forming current according to the pore-forming current sampling set SIk= (Ik1, IK2…), recorded as IK 平 ;

[0060] S13, traverse the corresponding pore-forming current in order from small to large pore-forming depth, and continuously exceed the average pore-forming current IK 平 Divided into independent formation groups, forming the formation group set SIk for pore current sampling 分 =(Ik 分 1.Ik 分 2…), continuously less than or equal to the average pore current IK 平 Divided into independent formation groups, forming the formation group set SIk for pore current sampling 分 =(Ik 分 1.Ik 分 2…), among which there are 3 formation groups with currents greater than the average value of the pore-forming current and 2 formation groups with currents less than or equal to the average value of the pore-forming current. Taking continuity as one of the criteria for determination can better group the same current characteristics into one group. When it is definitely discontinuous, it means that stratification occurs. When segmenting, different formation groups can also be labeled, such as hard formation groups and soft formation groups, so that different stratum colors corresponding to the labels can be configured in subsequent modeling.

[0061] S14, extract each pore current sampling formation group set SIk 分 =(Ik 分 1.Ik 分 2…), combined with the corresponding pore-making depth, the pore-making depths corresponding to the starting current and the end current of each formation group are calibrated as the starting pore-making depth and the end pore-making depth, forming five formation depth segments, recorded as segments: Lkq~Lkw, Lkq is the starting pore-making depth, and Lkw is the end pore-making depth.

[0062] Furthermore, according to the pore-forming current time curve and the pore-forming depth time curve, multiple current segments are calibrated based on the current anomaly segmentation and the corresponding formation depth segments are calibrated, which specifically includes the following steps:

[0063] S11, taking the pore-forming depth starting point as the reference point, obtaining the pore-forming depth at each interval of a particle scale, forming a pore-forming depth sampling set SLk=(Lk1, LK2...), obtaining the time corresponding to each pore-forming depth based on the pore-forming depth time curve, forming a time sampling set STk(TK1, TK2...), and then obtaining the pore-forming current corresponding to each pore-forming depth based on the corresponding time and the pore-forming current time curve, forming a pore-forming current sampling set SIk=(Ik1, IK2...);

[0064] S12, import the geological survey anomaly value IK of the borehole current 异 ;

[0065] S13, traverse the corresponding pore-forming current in order from small to large pore-forming depth, and continuously exceed the pore-forming current geological survey abnormal value IK 异 Divided into independent formation groups, forming the formation group set SIk for pore current sampling 分 =(Ik 分 1.Ik 分 2…), continuously less than or equal to the geological anomaly value IK of the borehole current 异 Divided into independent formation groups, forming the formation group set SIk for pore current sampling 分 =(Ik 分 1.Ik 分 2…);

[0066] S14, extract each pore current sampling formation group set SIk 分 =(Ik 分 1.Ik 分 2…), combined with the corresponding pore-making depth, the pore-making depth corresponding to the starting current and the end current of each formation group is calibrated as the starting pore-making depth and the end pore-making depth, forming a formation depth segment, recorded as segment: Lkq~Lkw, Lkq is the starting pore-making depth, and Lkw is the end pore-making depth.

[0067] Furthermore, the particle size is less than or equal to the average value of the difference between the depth at the start of the vibration compaction and the depth at the end of the vibration compaction during each vibration compaction.

[0068] Furthermore, the particle size is 0.3 m or 0.4 m.

[0069] Furthermore, the depth of each completed vibration compaction is specifically determined from the compaction depth time curve as follows: traverse the compaction depth time curve, and if a certain depth value is continuously maintained for a time longer than or equal to the vibration retention time, the depth is extracted as the depth of the completed vibration compaction. Figure 2 As shown in the curve, the leveling peak section is the depth when the compaction is completed. Within the leveling peak section, the continuous maintenance time exceeds the vibration retention time; the vibration retention time refers to the continuous vibration at a certain depth and maintaining it for a certain period of time.

[0070] Furthermore, the calculation method of the radius r of the gravel pile is as follows:

[0071] r = √Vm / π H, where the loose volume V" of the crushed stone filler is calculated based on the total crushed stone weight G and the loose density of the crushed stone filler, and the loose compacted volume Vm of the crushed stone filler is calculated based on Vm = V"*ρ; ρ is the density coefficient. √ represents the square root.

[0072] Furthermore, the pore-forming current time curve of the pore-forming section and the pore-forming depth time curve of the pore-forming section are obtained as follows:

[0073] During the hole-making process, the current and depth of the vibrator are continuously and simultaneously recorded, so as to obtain a hole-making current time curve and a hole-making depth time curve; from the hole-making current time curve and the hole-making depth time curve, the hole-leading section data is filtered out, and the hole-making section data is retained, so as to obtain a hole-making current time curve and a hole-making depth time curve of the hole-making section;

[0074] The compaction depth-time curve of the pore-making section is obtained as follows:

[0075] During the vibration compaction process, the depth of the vibrator is continuously recorded to obtain a compaction depth-time curve of the vibration compaction. From the compaction depth-time curve of the vibration compaction, the data of the hole-leading section is filtered out and the data of the hole-making section is retained to obtain the compaction depth-time curve of the hole-making section.

[0076] In a certain foundation construction, the strata are divided into the 5th, 4th and 3rd layers (stratum numbers). The 5th layer refers to the modern eroded gravel layer containing drifted sand. 2 ; Layer 4 refers to the fine-grained soil layer of the barrier lake phase IQ4 1 ; The third layer refers to the alluvial deposit containing drifted sand and gravel layer alQ3 3-2 . Gravel piles are structures set in the 5th and 4th layers. During general re-drilling, the boundary depth between the 5th and 4th layers, and the boundary depth between the 4th and 3rd layers can be determined by the stratification current. The 5th layer is generally drilled by introducing a hole, and the 4th layer is drilled by making a hole. Generally, the pile radius is calculated by treating the introduction and making a hole as a whole to calculate a radius as the radius of the entire gravel pile. This method cannot accurately characterize the gravel pile, especially the gravel pile in the drilling section. Generally, the radius of a single section of the compacted pile is calculated by a single amount of gravel and the difference in the compacted depth each time, and then the minimum radius is taken as the radius of the entire gravel pile. These methods cannot characterize gravel piles according to the stratification characteristics of the strata. In the project, the gravel divides the strata into large stratification intervals such as the 5th layer, the 4th layer, and the 3rd layer. However, in the 4th layer, i.e., the borehole section, there are also strata strata inside it. Therefore, the radius of the gravel pile will also vary with the different strata. For example, in the soft stratum interval, the radius is larger, and in the hard stratum interval, the radius is smaller. Therefore, in order to finely depict the three-dimensional model of the gravel pile in the borehole section, it is necessary to calibrate the radius and thickness of the gravel pile corresponding to different strata.

[0077] The present invention adopts three kinds of curve correlation calculation, samples at equal intervals, and finally calibrates the stratum stratification interval, thereby calibrating the thickness of different strata, and correlatively calculates the weight of gravel falling within the thickness range, and then calculates the radius of gravel piles in different strata, and finally calibrates two contour points of different strata, and finally fits the curve with the contour points, and then obtains the three-dimensional model of gravel piles with the contour curve.

[0078] In order to associate the crushed stone weight, compaction depth, pore depth and pore current, the present invention first creates a standard sample sequence, which is an equidistant pore depth. In this embodiment, 0.3 meters is used as the particle size. Figure 4 , Figure 1 , Figure 2 As shown, Figure 4 In the table, the depth is in meters and the current is in A. Figure 1 The hole-making current time curve and hole-making depth time curve are filtered out from the hole-making current time curve and hole-making depth time curve of the hole-making section; then the starting point and end point of the hole-making section depth are calibrated to obtain the hole-making current time curve and hole-making depth time curve of the hole-making section. Figure 4 Take 7 meters and 19.6 meters as an example, and then divide this interval with a particle size of 0.3 meters to obtain multiple point values ​​of the borehole depth, and then use these point values ​​to find the corresponding time from the borehole depth time curve. Since the time of the borehole depth time curve is consistent with the time of the borehole current time curve, multiple borehole currents are further extracted from the borehole current time curve based on the same time, and then segmented based on the average value of these borehole currents or the geological anomaly of the borehole current. Segmentation is performed based on the average value of these borehole currents, 165A, and 3 independent segments greater than and 2 less than the average value of 165A can be obtained. These current segments are in the process of borehole making. Due to different formations, the output current of the borehole vibrator is different, so the formation stratification can be seen. After the current is stratified, each borehole current sampling formation grouping set SIk is extracted 分 =(Ik 分 1.Ik 分 2…), combined with the corresponding pore-making depth, the pore-making depth corresponding to the starting current and the end current of each formation group is calibrated as the starting pore-making depth and the end pore-making depth, forming a formation depth segment, recorded as segment: Lkq~Lkw, Lkq is the starting pore-making depth, Lkw is the end pore-making depth. Figure 4 As shown in the figure, five stratigraphic segments can be obtained. This process can be understood as constructing a standard sample sequence first, extracting actual samples by searching the curve parameters through the standard sample sequence, and then segmenting the actual samples, thereby calibrating the stratigraphic layers that meet the current anomaly correlation. The stratigraphic layers are calibrated with a boundary scale between two layers. Since the depth of each compaction is recorded in the compaction process, each compaction depth can be traversed to fall into different stratigraphic layers. Thus, the total crushed stone weight G of each stratigraphic layer is obtained, and then the radius of each stratigraphic layer is further calculated. So far, for each stratigraphic layer, the corresponding boundary depth and radius are calculated respectively. Then, a three-dimensional model is formed by fitting the contour curve and three-dimensional modeling.

[0079] Among them, the particle size cannot be a large parameter, and must be less than or equal to the average value of the difference between the depth at the start of each vibration and the depth at the end of each vibration. In this way, the accuracy of the set standard sample sequence is higher, and at least the amount of crushed stone in a single compaction section is included. Each formation segment contains the amount of crushed stone in multiple compaction sections, avoiding the problem of poor consistency and achieving a moderate fitting effect.

[0080] like Figure 5 As shown, the radii of the five segments are 0.68 m, 0.77 m, 0.61 m, 0.71 m, and 0.63 m, respectively. The depths of the five stratigraphic segments are: 7 m to 9.1 m, 9.4 m to 11.2 m, 11.5 m to 16 m, 16.3 m to 18.1 m, and 18.4 m to 19.9 m, respectively.

[0081] According to these depths and their radii, 10 coordinate points are created accordingly, and then fitted to form Figure 5 Based on this curve as the contour curve of the gravel pile, the three-dimensional entity rotation operation in the three-dimensional modeling is used to construct a three-dimensional model of the gravel pile; the three-dimensional model is imported into the quality analysis system for information display of the corresponding pile number.
