Description

Technical Field

[0001] This invention relates to the field of building pile foundation engineering technology, and in particular to a method and apparatus for determining the mutual influence effect coefficient of piles. Background Technology

[0002] In building construction, pile foundations are a common type of foundation used to transfer the loads of the superstructure to the deep foundation soil. Pile groups, as a type of pile foundation, bear loads through the coordinated action of multiple piles. Traditional pile group arrangements include strip, rectangular, or staggered patterns. The pile interaction effect coefficient is a key component of the pile group effect coefficient, directly affecting the assessment of the horizontal bearing capacity of the pile group.

[0003] However, traditional pile placement methods have limitations. For special structures like LNG (Liquefied Natural Gas) storage tanks, their foundations often employ a coordinated approach with square piles in the center and 2-3 rings of piles around the perimeter. This pile placement better adapts to the circular structure and load distribution of the tank, but current standards do not provide methods for calculating the mutual influence coefficients for this type of pile placement. This leads engineers to rely on experience or simplified models in actual design, potentially overestimating or underestimating the effects of pile groups, thus impacting structural safety and economic efficiency.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] Pile foundations under buildings often exist in the form of pile groups. There are various traditional pile group arrangements, such as strip, rectangular, or quincunx arrangements. Different arrangements directly affect the interaction between the piles in the group and their interaction with the soil, thereby affecting the magnitude of the pile group effect coefficient and the horizontal bearing capacity of the pile group.

[0023] LNG storage tanks are typically large cylindrical structures, with diameters reaching tens of meters, and their foundations must withstand enormous horizontal loads (such as wind loads and seismic forces). Traditional rectangular pile layouts may experience stress concentration in the central area, while peripheral ring pile layouts can effectively distribute the load. However, due to a lack of relevant theoretical support, the values ​​of the pile interaction effect coefficients in current designs are uncertain, potentially leading to inaccurate calculations of the pile group efficiency coefficient and affecting the estimation of horizontal bearing capacity. Therefore, a method for calculating the interaction effect coefficients of square-circular collaborative pile layouts is urgently needed to fill the gaps in the specifications.

[0024] Based on this, this invention proposes a method for determining the mutual influence effect coefficient of piles, specifically a method for calculating the square-circular synergistic pile layout effect coefficient for LNG storage tank pile foundations. By introducing a new method for calculating the mutual influence effect coefficient, this method addresses the problem that traditional specifications do not cover special pile layout configurations. This method considers the synergistic effect of the central square pile layout and the outer ring pile layout, enabling a more accurate assessment of the pile group effect coefficient and horizontal bearing capacity.

[0025] The following is combined Figures 1-3 The present invention describes a method and apparatus for determining the mutual influence coefficient of piles.

[0026] Figure 1 This is a flowchart illustrating the method for determining the mutual influence coefficient of piles provided by the present invention, as shown below. Figure 1 As shown, the method includes the following: Step 101: Obtain the pile diameter of the target pile in the pile group, the pile spacing between the target pile and its adjacent piles, the number of piles in the inner square layout, and the number of piles in the outer ring layout.

[0027] A target pile refers to a specific pile in a pile group foundation with a square-circular coordinated pile arrangement, whose mutual influence coefficient is to be evaluated. This invention calculates the effect coefficient distribution of the entire pile group by treating each pile in the pile group as a target pile.

[0028] Pile diameter refers to the design diameter or equivalent diameter of the target pile. For non-circular cross-section piles (such as square piles and pipe piles), their equivalent diameter can be converted to the diameter of a circular cross-section based on the principle of equal cross-sectional area. Pile diameter is a fundamental parameter characterizing the geometric dimensions of the pile and affecting its contact area and stiffness with the soil.

[0029] The pile spacing is the projected distance between the center of the target pile and the center of any adjacent pile, measured along the preset horizontal load direction.

[0030] The number of piles in the inner square layout refers to the total number of all piles located within the inner square layout area determined by the design in a square-circle coordinated pile layout configuration.

[0031] The number of piles in the outer ring refers to the total number of all piles located within the outer ring area determined by the design in a square-circular coordinated pile layout.

[0032] In this invention, the pile group employs a collaborative pile arrangement combining an inner ring of square piles and an outer ring of circular piles. It should be understood that the inner ring of square piles refers to a pile arrangement where, in the central part of the pile group area, the piles are arranged according to a regular planar grid, so that the lines connecting the pile positions form one or more rectangular or square grids on a top-view plan. The outer ring of circular piles refers to a pile arrangement where, outside the inner ring of square piles, the piles are arranged along the trajectory of one or more concentric rings. The collaborative pile arrangement combining the inner ring of square piles and the outer ring of circular piles means that the inner ring of square piles and the outer ring of circular piles are directly adjacent and without gaps in the planar projection, together forming a complete pile group foundation for supporting the same circular pile cap. The piles in both pile areas work together through the circular pile cap and the foundation soil to jointly resist vertical loads, horizontal loads, and overturning moments. For example, refer to... Figure 2 , Figure 2 Four different pile layout methods are given: the outer ring is a circular pile layout and the inner ring is a rectangular pile layout, including four cases: 2×2, 3×3, 4×4, and 5×5, with a total number of piles of 12, 21, 32, and 45 respectively.

[0033] The process involves obtaining the pile diameter of the target pile, the pile spacing between the target pile and its adjacent piles, the number of piles in the inner ring square layout, and the number of piles in the outer ring circular layout. For example, the design value of the target pile's pile diameter is extracted from the digital design model of the collaborative pile layout; based on the spatial coordinates of the pile positions in the digital design model, the straight-line distance between the center point of the target pile and the center point of its nearest adjacent pile is calculated as the pile spacing; according to the preset pile layout area division rules, all piles located within the inner ring square layout area are identified and counted in the digital design model to obtain the number of piles in the inner ring square layout; according to the preset pile layout area division rules, all piles located within the outer ring circular layout area are identified and counted in the digital design model to obtain the number of piles in the outer ring circular layout.

[0034] In one embodiment, the number of adjacent piles, the number of inner ring square piles, and the number of outer ring circular piles can be determined according to the following rules: a circular influence area is delineated with the center of the target pile as the center and a preset horizontal influence radius R as the radius. Other piles within the circular influence area are identified as adjacent piles that affect the target pile. The number of adjacent piles belonging to the inner ring square pile area is counted as the number of inner ring square piles. The number of adjacent piles belonging to the outer ring circular pile area is counted as the number of outer ring circular piles.

[0035] Step 102: Based on the pile diameter and the pile spacing, determine the spatial location factor that reflects the influence of the pile spacing.

[0036] Calculate the ratio of pile spacing to pile diameter, and determine the spatial location factor based on this ratio. The spatial location factor is a power function of the ratio, and the exponent of the power function represents the influencing factors related to pile diameter and pile spacing.

[0037] Step 103: Based on the number of square piles in the inner circle and their correction coefficients, and the number of ring piles in the outer circle and their correction coefficients, determine the superposition influence factor reflecting the group interaction under the collaborative pile layout method.

[0038] The correction coefficients for the number of piles in the inner square pile layout and the outer ring pile layout are different values, used to characterize the average strength difference of the piles in the inner square pile layout area and the outer ring pile layout area in terms of the unit influence on the target pile under the collaborative pile layout method.

[0039] The product of the number of square piles in the inner circle and their correction coefficient is summed with the product of the number of piles in the outer circle and their correction coefficient. The superposition influence factor is determined based on the summation result.

[0040] Step 104: Based on the spatial location factor and the superposition influence factor, determine the mutual influence effect coefficient of the target pile.

[0041] Divide the spatial location factor by the superposition influence factor, and use the resulting quotient as the mutual influence effect coefficient of the target pile.

[0042] The method for determining the mutual influence effect coefficient of piles provided in this invention involves obtaining the pile diameter of the target pile in a pile group, the pile spacing between the target pile and its adjacent piles, the number of piles in the inner circle of square arrangement, and the number of piles in the outer circle of ring arrangement. Based on the pile diameter and pile spacing, a spatial location factor reflecting the influence of pile spacing is determined. Based on the number of piles in the inner circle of square arrangement and its correction coefficient, and the number of piles in the outer circle of ring arrangement and its correction coefficient, a superposition influence factor reflecting the group interaction under the cooperative pile arrangement is determined. Based on the spatial location factor and the superposition influence factor, the mutual influence effect coefficient of the target pile is determined. This invention overcomes the shortcomings of low accuracy and poor reliability caused by relying on manual experience estimation by constructing a spatial location factor reflecting the influence of single pile spacing and a superposition influence factor reflecting the differences in the spatial interaction of the group, and finally comprehensively determining the effect coefficient. This achieves accurate evaluation of the pile group effect under the square-circle cooperative pile arrangement, improving the reliability and economy of pile foundation design for structures such as LNG storage tanks.

[0043] Based on the above embodiments, determining the spatial location factor reflecting the influence of pile spacing based on the pile diameter and the pile spacing includes: Calculate the first ratio of the pile spacing to the pile diameter; The spatial location factor is determined based on the first ratio and the influence factors related to the pile diameter and the pile spacing.

[0044] It should be understood that influencing factors Used to quantify pile spacing-to-diameter ratio A nonlinear index reflecting the degree of influence of pile-soil interaction. The influencing factors comprehensively reflect the working behavior of the pile-soil system under horizontal loads. Its magnitude depends on soil properties, pile stiffness, and the overall spatial arrangement of the pile group, and is closely related to the number of piles in the inner square arrangement and the number of piles in the outer ring arrangement.

[0045] Obtain the influencing factors related to pile diameter and pile spacing. For example, based on the soil type and pile density level of the pile group, consult a pre-established engineering experience value comparison table to obtain the recommended values ​​for the corresponding influencing factors. Alternatively, the influencing factors can be directly read from the additional attributes of the digital design model of the pile group, where they are pre-assigned as calculation parameters related to pile diameter and pile spacing in the design model. Alternatively, the influencing factors can be calculated based on the geometric parameters of the inner ring square pile arrangement and the outer ring ring pile arrangement through a preset functional relationship; where the preset functional relationship is linear, the influencing factor equals the product of a set coefficient and the sum of the parameters of the inner ring square pile arrangement and the outer ring ring pile arrangement, plus a constant term.

[0046] Calculate the first ratio of pile spacing to pile diameter. Using this first ratio as the base and the influencing factor as the exponent, perform a power operation. The result of this power operation is determined as the spatial location factor. For example, the spatial location factor is calculated as follows: .

[0047] The embodiments of the present invention introduce and calculate the ratio of pile diameter to pile spacing, and apply nonlinear correction to it using influencing factors, thereby scientifically constructing a spatial location factor that reflects the distance effect between individual piles.

[0048] Based on the above embodiments, determining the superimposed influence factor reflecting the group interaction under the cooperative pile layout method, based on the number of piles in the inner ring square layout and its correction coefficient, and the number of piles in the outer ring ring layout and its correction coefficient, includes: Calculate the first product of the number of square piles in the inner circle and its correction coefficient, and calculate the second product of the number of piles in the outer ring and its correction coefficient; The superposition influence factor is determined based on the first product, the second product, and the constant adjustment term.

[0049] The calculation method for the superimposed impact factor is as follows: ; in, The first product, The second product, It is a constant.

[0050] This invention achieves refined separation and quantification of the differentiated contributions of two different pile layout regions (inner square and outer circle) to the pile group effect by calculating the product of the number of piles in the inner and outer rings and the corresponding correction coefficients. A constant adjustment term is then introduced to calibrate the results overall. The resulting superimposed influence factor can more scientifically and flexibly reflect the complex spatial interactions of the pile group under coordinated pile layout. This method overcomes the limitation of traditional models that treat pile groups as homogeneous bodies, providing key theoretical parameters for accurately evaluating the pile bearing capacity of this special pile layout.

[0051] Based on the above embodiments, determining the mutual influence coefficient of the target pile based on the spatial location factor and the superposition influence factor includes: Calculate the second ratio of the spatial location factor to the superposition influence factor, and use the second ratio as the mutual influence effect coefficient of the target pile.

[0052] In one embodiment, the mutual influence effect coefficient is calculated based on the following formula: ; in, The coefficient representing the mutual influence effect of the piles. The diameter of the pile. The pile spacing To reflect the spatial location factor that reflects the influence of pile spacing, These are the influencing factors related to pile diameter and pile spacing. It is a constant. The number of square piles in the inner circle. This refers to the number of piles in the outer ring. for Correction factor, for Correction factor, It is a constant. This is for the superimposed influence factors.

[0053] Optionally, before using the second ratio as the interaction effect coefficient of the piles, if the second ratio is greater than a preset upper threshold, it is corrected to the upper threshold; if the second ratio is less than a preset lower threshold, it is corrected to the lower threshold.

[0054] In one embodiment, the formula for calculating the mutual influence effect coefficient can be determined in the following way: The soil was modeled using the Mohr-Coulomb (MC) model, and the soil material parameters are shown in Table 1.

[0055] Table 1 Soil Material Parameters Pile foundation and cap structure: The cast-in-place piles and caps are simulated using linear elastic materials; the elastic modulus is 32.5 GPa, the Poisson's ratio is 0.15, and the side friction is automatically calculated based on the adjacent soil layers.

[0056] Simulation results: Under the condition of pile top embedment, when the pile load is 900kN, the deformation at the pile top position when a single pile is embedded is about 6.6mm. The deformation of each pile group foundation under the circular arrangement is shown in Table 2. From this, the mutual influence effect coefficient of the piles can be obtained.

[0057] Table 2. Values ​​of the mutual influence coefficients for piles arranged in a circular pattern. Based on the results in the table above, a formula fitting can be performed to obtain the estimation formula for the mutual influence effect coefficient of piles in a circular pile group foundation: ; Among them, the influencing factors are: .

[0058] The above empirical formulas are based on finite element numerical simulations of pile group foundations with various pile number configurations. In the numerical simulations, the soil adopts the Mohr-Coulomb constitutive model, and the piles and pile caps adopt the linear elastic model. The benchmark values ​​of the mutual influence effect coefficients are determined by comparing the pile top displacements of single piles and pile groups under the same load. Among them, the fitting error of the four sets of results in Table 2 is 1.67%.

[0059] This invention proposes a coefficient for the mutual influence effect of piles on commonly used pile groups under LNG storage tanks when using a square-circular coordinated pile layout. The calculation enables a correct evaluation of the overall efficiency coefficient of the pile group. The range of values ​​for this value provides support for accurately predicting the horizontal bearing capacity of pile groups.

[0060] Based on the above embodiments, the method further includes: Based on the mutual influence effect coefficient of the target piles, the efficiency coefficient of the pile group is determined; The horizontal bearing capacity of the pile group is evaluated based on the pile group efficiency coefficient.

[0061] It should be understood that the efficiency coefficient of pile groups η h The comprehensive reduction (or enhancement) factor used to calculate the design value of the horizontal bearing capacity of pile group foundations is determined by the mutual influence effect coefficient of the target piles and other adjustment factors specified in the specifications or related to the project.

[0062] The efficiency coefficient of the pile group is determined based on the mutual influence effect coefficient of the target piles. For example, the formula for calculating the efficiency coefficient of the pile group is: η h = η i ×Other factors; Other factors may include the pile cap effect coefficient, the soil compression effect coefficient between piles, the load eccentricity, the adjustment coefficient for working conditions such as seismic action, and other safety factors or reduction factors determined according to the code provisions or local experience.

[0063] Optionally, the pile group efficiency coefficient for evaluating the overall horizontal bearing capacity of the pile group can be determined based on the mutual influence effect coefficients of all or some of the piles in the pile group, using a weighted average or representative value selection method. The weighted average method involves weighting the mutual influence effect coefficients of each pile according to its individual pile horizontal bearing capacity characteristic value to calculate the pile group efficiency coefficient.

[0064] The horizontal bearing capacity of a pile group is evaluated based on the pile group efficiency coefficient. For example, the horizontal bearing capacity of a pile group. R ha The calculation formula is: R ha = η h ×Σ R ua ; Where, Σ R ua It is the sum of the characteristic values ​​of the horizontal bearing capacity of each individual pile in the pile group. Rua The characteristic value of the horizontal bearing capacity of a single pile can be determined based on field static load tests, theoretical calculations, or local empirical parameters.

[0065] The calculated design value of horizontal bearing capacity is compared with the design value of the combined horizontal load acting on the pile foundation to verify its safety.

[0066] This invention solves the problem of the lack of standards for inner square and outer circle pile foundations by scientifically synthesizing the single pile effect coefficient into an overall efficiency coefficient and using it for bearing capacity assessment. It provides a reliable theoretical tool for optimizing layout and reducing costs while ensuring safety.

[0067] The following describes the device for determining the mutual influence coefficient of piles provided by the present invention. The device for determining the mutual influence coefficient of piles described below and the method for determining the mutual influence coefficient of piles described above can be referred to in correspondence.
