[0002] As an important development business in the nuclear power field, the design quality of offshore wind power projects has always been the focus. In the foundation design of offshore booster stations in offshore wind power projects, pile foundation checking work is crucial. In order to ensure the design quality, the pile body structure strength, the supporting capacity of the foundation soil to the pile, and the pile body settlement and horizontal deformation need to be checked. At present, the commonly used calculation software is large general finite element analysis software (ANSYS) and offshore structure design analysis software (SACS). At present, the design personnel usually use the P-Y curve method (composite foundation counterforce method) to simulate the nonlinear relationship of pile-soil interaction when simulating the pile-soil interaction, and use the form of manual and EXCEL auxiliary combination to calculate the parameters, and finally manually convert the input files required by SACS and ANSYS.

[0003] The manual calculation of P-Y data (the data between the soil counterforce P at a depth of X below the mud surface and the deflection Y of the pile at the point under the action of horizontal load) of this scheme has the following shortcomings:

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the application.

[0054] REFERENCE Figure 1 It is a flow schematic diagram of a preferred embodiment of the sea wind foundation pile soil data processing method provided by the application.

[0055] Specifically, as shown in the figure, Figure 1 The sea wind foundation pile soil data processing method comprises the following steps:

The TZ curve represents the relationship between the axial bond force or side friction of the pile and the local vertical displacement of the pile. The QZ curve represents the relationship between the pile tip bearing capacity and the pile tip vertical displacement. The PY curve method is the composite foundation reaction method.

[0061] In some embodiments, inputting the calculation parameters for the sea breeze foundation pile soil includes: batch importing the calculation parameters for the sea breeze foundation pile soil; or, inputting the calculation parameters for the sea breeze foundation pile soil row by row. That is, the input of the calculation parameters for the sea breeze foundation pile soil can be achieved by batch importing or by manually inputting them row by row.

[0062] Alternatively, in this embodiment of the invention, the calculation parameters can be imported in batches using an Excel template via the interface of the Office software. For example... Figure 2 As shown, taking the input of soil layer design parameter data as an example, the soil layer design parameters are first entered into the specified input template in Excel.

[0064] Furthermore, in this embodiment of the invention, commonly used curve design parameters can be pre-stored in the memory and can be directly called when needed. Moreover, in practical applications, designers can modify them as needed.

[0065] Step S102, based on the calculation parameters, the calculation is carried out to obtain the intermediate result data of the sea wind foundation pile soil.

[0066] In some embodiments, based on the calculation parameters, the calculation is carried out to obtain the intermediate result data of the sea wind foundation pile soil, including: based on the calculation parameters, the clay intermediate data is calculated to obtain the intermediate result data of the clay; based on the calculation parameters, the sand soil intermediate data is calculated to obtain the intermediate result data of the sand soil; the intermediate result data of the clay and the intermediate result data of the sand soil are the intermediate result data of the sea wind foundation pile soil.

[0067] For clay, the following calculations are required: that is, based on the calculation parameters, the clay intermediate data is calculated to obtain the intermediate result data of the clay, including: based on the calculation parameters, the clay soil resistance and the deflection of the pile at the preset point below the mud surface are calculated to obtain the PY data of the clay; based on the calculation parameters, the axial adhesion or lateral friction of the pile soil at the preset point below the mud surface and the local vertical displacement of the pile at the preset point below the mud surface are calculated to obtain the TZ data of the clay; based on the calculation parameters, the pile end bearing capacity and the pile end vertical displacement of the clay are calculated to obtain the QZ data of the clay; the PY data of the clay, the TZ data of the clay and the QZ data of the clay are the intermediate result data of the clay.

[0068] Under the action of horizontal static or cyclic load, the soil resistance P at the preset point below the mud surface, the deflection Y of the pile at the point, the axial adhesion or lateral friction T of the pile soil, the local vertical displacement Z1 of the pile, the pile end bearing capacity Q and the pile end vertical displacement Z2 of the clay.

[0069] For the calculation of the PY data of the clay:

[0070] (1) Calculation of the clay soil resistance P at the depth X below the mud surface:

[0071] Obtain the undisturbed clay pattern, the undrained shear strength c, calculate the depth X of the soil resistance reduction area below the mud surface R , the unit effective gravity γ of the clay, the dimensionless empirical constant J, and the calculation limit soil resistance p u . Among them, the unit effective gravity γ of the clay can be automatically selected according to the soil condition and the depth X in the soil parameters. For the stubborn empirical constant J, it is generally 0.25-0.5, and the designer can select it according to the actual soil condition in actual calculation. The depth X below the mud surface is automatically selected.

[0072] (2) Calculation of the deflection Y of the pile at the depth X below the mud surface:

[0073] εc is selected, the strain of the limit strength of the undrained compression test of the cohesive soil; the lateral displacement deformation y of the pile when the soil around the pile reaches half of the limit soil resistance c is calculated.

[0074] wherein the ultimate soil resistance p u can be calculated according to the following formula:

[0075] p u = 3c + γX + J(cX / D) (1)

[0076] p u = 9c for X ≥ X R (2)

[0077] (1) wherein D is the diameter of the pile.

[0078] Under static load: according to the PY curve parameter table, the PY data of clay is calculated according to discrete points. Specifically, the calculation method of PY data needs to calculate 6 PY data corresponding to each depth X, that is, 6 sample points need to be calculated, each sample point is a pair of (P, Y) values, and the six data in Table 1 correspond to six samples. Specifically, take the first sample as an example, P / p u = 0 to find P = 0, and similarly Y / y c = 0 to find Y = 0, so the first point is (0, 0)

[0079] The second point P / p u = 0.23, P = 0.23 * p u , p u is calculated according to formula (1) or formula (2), Y / y c = 0.10 at this time, Y = y c *0.10, and the (P, y) of the second point is found.

[0080] wherein X R can be calculated according to the following formula:

[0081] X R = 6D / ((γD / c) + J) (3)

[0082] Under cyclic load: Y is calculated according to discrete points, and P is calculated according to the formula under different conditions. Specifically, the calculation method of Y is unchanged, and the calculation method of P is as follows:

[0083] When X ≤ X R and Y / y c < = 3, P = P u *0.5*(Y / Yc)^(1 / 3);

[0084] When X ≤ X R and 3 < Y / y c ≤ 15, P = 0.72*P u *D*(1-(1-X / X R)*((Y-Yc) / (12*Yc)))*D;

[0085] When X>X R and Y / y c <=3, P=Pu*0.5*(Y / y c )^(1 / 3);

[0086] When X>X R and Y / y c >3, P=0.72.

[0087] Specifically, first calculate the ultimate soil resistance p u according to formula (1) or formula (2). According to the clay PY curve parameter table in table 1, the deflection Y can be calculated according to the sample point data in table 1 and the above method.

[0088] Table 1 clay PY curve parameter table

[0090] For the calculation of clay TZ (here Z is represented by Z1) data:

[0091] (1) The calculation of the axial bond force or lateral friction resistance T of the pile soil at a depth of X below the mud surface:

[0092] Calculate the dimensionless coefficient α, obtain the undrained shear strength c of the disturbed clay pattern, and calculate the axial ultimate bearing capacity T max of the pile. According to the clay TZ1 curve parameter, the axial bond force or lateral friction resistance T of the pile soil is equal to the product of the corresponding parameter and the axial ultimate bearing capacity T max of the pile.

[0093] (2) The calculation of the local vertical displacement Z1 of the pile at a depth of X below the mud surface:

[0094] According to the clay TZ1 curve parameter, the local vertical displacement Z1 of the pile is equal to the product of the corresponding parameter and the pile diameter D.

[0095] The data of Z1 / D and t / t max in the clay TZ1 curve parameter table are regarded as a standard function. At this time, according to the above calculation, the axial ultimate bearing capacity t max of the pile can be obtained, and the corresponding T and Z1 values of each sample point can be calculated according to the TZ1 curve parameter table. Generally, five sample points are calculated.

[0096] Specifically, first calculate Tmax:

[0097] The coefficient α can be calculated by the following formula:

[0098] a = 0.5p 0.5 ( p < 1.0) (3)

[0099] a = 0.5p -0.25 ( p > 1) (4)

[0100] Wherein, the constraint condition of coefficient a is: a < 1.0.

[0101] Clay T max Satisfies:

[0102] T max = a * c (5)

[0103] T and Z1 calculation method and PY calculation method is same, each depth according to table 2 selects five sample points, calculates the value of each sample point. With the third sample point as an example:

[0104] T / t max = 0.50, can calculate: T = 0.50 * t max ;

[0105] Z1 / D = 0.0016, can calculate: Z1 = 0.0016 * D.

[0106] Therefore, (T, Z1) value of this sample can be solved.

[0109] For the calculation of clay QZ (herein Z is represented by Z2) data:

[0110] When the depth X below the mud surface is equal to the length of the pile, the pile end bearing capacity Q and the pile end vertical displacement Z2 need to be calculated.

[0111] (1) the calculation of pile end bearing capacity Q:

[0112] Get the current depth c, calculate the limit pile end bearing capacity Q p . According to the clay QZ2 curve parameters, the pile end bearing capacity Q of the pile soil is equal to the product of the corresponding parameters and the Q P of the pile.

[0113] (2) the calculation of pile end vertical displacement Z2:

[0114] According to the clay QZ2 curve parameters, the pile end vertical displacement Z2 is equal to the product of the corresponding parameters and the pile diameter D.

[0115] Z2 / D and Q / Q PThe data corresponding table is regarded as a standard function. At this time, the axial ultimate bearing capacity T of the pile can be obtained according to the above calculation max Then, the Q and Z2 values corresponding to each sample point are calculated according to the QZ2 curve parameter table. Generally, five sample points are calculated.

[0116] Specifically, the ultimate pile end bearing capacity Q p The Q value can be calculated by the following formula:

[0117] Q P = 9*c (6)

[0118] Taking sample 3 as an example:

[0119] As shown in Table 3: Q / Q P = 0.75, Z2 / D = 0.042, and Z2 = D*0.042 can be calculated. D is the pile diameter and can be directly obtained. Therefore, the vertical displacement Z2 of the pile end can be calculated based on the D value. The Q value can be calculated by formula (6).

[0121] Sample Z / D Q / Q P ]]> 1 0.002 0.25 2 0.013 0.50 3 0.042 0.75 4 0.073 0.90 5 0.100 1.00

[0122] For sandy soil, the following calculations are needed: that is, based on the calculation parameters, the intermediate data of sandy soil are calculated to obtain the intermediate result data of sandy soil, including: based on the calculation parameters, the deflection of the pile at a preset point below the depth of the mud surface and the soil reaction of the sandy soil are calculated to obtain the PY data of the sandy soil; based on the calculation parameters, the axial cohesion or lateral friction of the pile soil at the preset point below the depth of the mud surface and the local vertical displacement of the pile are calculated to obtain the TZ data of the sandy soil; based on the calculation parameters, the pile end bearing capacity and the pile end vertical displacement of the sandy soil are calculated to obtain the QZ data of the sandy soil; the PY data of the sandy soil, the TZ data of the sandy soil and the QZ data of the sandy soil are the intermediate result data of the sandy soil.

[0123] The soil reaction P at a depth X below the mud surface and the deflection Y of the pile at the point, the axial cohesion or lateral friction T of the pile soil and the local vertical displacement Z1 of the pile, and the pile end bearing capacity Q and the pile end vertical displacement Z2 are calculated.

[0124] For the calculation of the PY data of the sandy soil:

[0125] (1) Calculation of the deflection Y of the pile at a depth X below the mud surface:

[0126] The deflection Y of the pile at a depth X below the mud surface of the sandy soil can be directly obtained according to the deflection Y curve parameters of the sandy soil pile.

[0127] Specifically, as shown in Figure 4, for each depth, we can directly take the values ​​of the 6 sample points in Table 4: Y1 = 0, Y2 = 0.01, Y3 = 0.03, Y4 = 0.08, Y5 = 0.2, and Y6 = 1. The P-value below will be calculated based on this Y value.

[0131] Obtain the internal friction angle of sand Calculate coefficients C1, C2, and C3, where coefficients C1, C2, and C3 can be calculated using a fitting function, such as... Figure 4 As shown; the effective unit weight γ of the soil can be selected according to the soil properties and depth; the coefficient A is calculated considering the cyclic load and static load conditions; the deflection Y of the pile at a depth X below the mud surface (calculated in (1) above) is used to calculate the initial modulus k of the foundation reaction force, and the functional relationship of the internal friction angle is determined; the ultimate soil resistance p us and p ud The calculation is performed, with subscript s representing shallow layers and d representing deep layers.

[0132] Substituting the above calculation results into formula (7) will yield the soil reaction force P at a depth of X below the mud surface.

[0133] P = A × p u ×tanh[(k×H) / (A×p u )×Y] (7)

[0134] In formula (7), when in a shallow layer, p u =p us When at a deeper level, p u =p us .

[0135] Based on six samples of the deflection of the pile at a depth X below the mud surface, six sample values ​​of the corresponding soil reaction force P in the sand can be calculated.

[0146] t max = f = Kp c tan δ (8)

[0147] Where f cannot exceed the limit value in Table 5. The calculation method of TZ is the same as PY, and 4 sample points are selected at each depth, and 4 pairs of (T, Z) values are calculated. Referring to Table 6, take sample point 3 as an example:

[0148] From Table 6, we can get: T / t max = 1, Z / D = 0.05, so we can get T = t max , Z = 0.05*D; obtain a pair of (T, Z) values.

[0149] For the calculation of sandy soil QZ data:

[0150] When the depth X below the mud surface is equal to the pile length, the pile tip bearing capacity Q and the pile tip vertical displacement Z2 need to be calculated.

[0151] (1) Calculation of pile tip bearing capacity Q:

[0152] Calculate the effective gravity p0 of the soil at the current depth; automatically select Nq at the current depth; calculate the limit pile tip bearing capacity Q P .

[0153] According to the QZ curve parameter of sandy soil, the pile tip bearing capacity Q of the pile-soil is equal to the product of the corresponding parameter and the Q Pthe product of the corresponding parameter and the pile diameter D.

[0154] (2) Calculation of the vertical displacement Z2 of the pile tip:

[0155] According to the sand QZ curve parameters, the vertical displacement Z2 of the pile tip is equal to the product of the corresponding parameter and the pile diameter D.

[0156] The data pair of Z2 / D and Q / Q P in the sand QZ curve parameter table is regarded as a standard function. At this time, according to the above calculation, the axial ultimate bearing capacity t max of the pile can be obtained, and then the Q and Z2 values corresponding to each sample point are calculated according to the QZ2 curve parameter table. Generally, five sample points are calculated.

[0157] Table 7 Sand QZ curve parameters

[0158] Sample Z2 / D Q / Q P ]]> 1 0.002 0.25 2 0.013 0.50 3 0.042 0.75 4 0.073 0.90 5 0.100 1.00

[0159] Specifically, as shown in Table 7, taking sample 3 as an example, from Table 7, it can be seen that Q / Q P = 0.75, and Q P = Nq * p0, so Q = 0.75 * Q P can be obtained. Therefore, after the ultimate pile tip bearing capacity Q p of the sand is calculated, the pile tip bearing capacity Q of the sand can be calculated. Similarly, the vertical displacement Z2 of the pile tip of the sand can be quickly calculated by referring to Table 7 and the pile diameter.

[0160] Through the above method, the PY data of clay, the TZ data of clay and the QZ data of clay, the PY data of sand, the TZ data of sand and the QZ data of sand can be calculated respectively.

[0161] Step S103, checking the intermediate result data to determine whether the intermediate result data is qualified.

[0162] Step S104, if qualified, outputting the intermediate result data.

[0163] Step S105, if not qualified, adjusting the calculation parameters of the sea wind foundation pile soil.

[0164] In some embodiments, during the sea wind foundation pile soil data processing process, the designer needs to check the intermediate result data, that is, the PY data of clay, the TZ data of clay and the QZ data of clay, the PY data of sand, the TZ data of sand and the QZ data of sand are checked to determine whether the intermediate result data is qualified. Specifically, when these intermediate result data meet the curve trend, it is determined that the intermediate result data is qualified, otherwise it is determined as unqualified. When it is determined as unqualified, the design parameters need to be selected again for recalculation until the curve meets the requirements.

[0165] In the original intermediate data result checking mode: the designer manually selects data according to the calculation result, and then draws a PY, TZ and QT curve by using Excel to draw a table to manually check the accuracy of the data. If the curve is not drawn ideally, the curve needs to be deleted and redrawn repeatedly. This work is relatively cumbersome and time-consuming. The present application adopts a new checking mode: the user can directly select the required data on the operation interface, and can directly click on the "draw PY curve", "draw TZ curve" and "draw QZ curve" on the corresponding interface to pop up the corresponding drawing interface and curve. The user can also set the maximum value, minimum value and interval size according to the needs, which is very convenient.

[0166] Further, in the embodiment of the present application, the user can also output the PY data, TZ data and QZ data to the local computer by clicking the "output intermediate result" button on the main interface. At this time, the system can automatically draw the corresponding curve in the Excel table according to the user's needs, so as to be used by the designer.

[0167] Further, in the embodiment of the present application, the output intermediate result data includes: judging whether the output data trigger signal is received; if yes, converting the intermediate result data into interface data corresponding to the output data trigger signal and outputting.

[0168] Specifically, in the embodiment of the present application, after the intermediate data checking is completed, the ANSYS and SACS interface data files can be output. The original data output is that the designer manually calculates and inputs into the corresponding TXT file according to the PY, TZ and QZ data and the ANSYS and SACS interface data rules. The calculation process is cumbersome, the workload is large, the human error is more, and the error cannot be found. Moreover, the software has a strict requirement on the number and position of spaces, so the accuracy of the calculation cannot be guaranteed.

[0169] According to the ANSYS and SACS interface data rules, the present application uses computer technology to connect with the TXT file interface, realizes the one-key data generation function. The designer only needs to click "SCAS output" and "ANSYS output" to see the file output to the specified directory. This completely releases the designer from the heavy work, and guarantees the accurate calculation of the Haifeng foundation pile soil analysis, which lays a solid foundation for the smooth development of the Haifeng project. The output data trigger signal is the signal generated by the designer clicking the "SCAS output" button or the "ANSYS output" button.
