[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The embodiment of the present invention provides a method for determining design parameters of intelligent vibro-stone piles. In order to explain the method, the basic knowledge of stone pile design is first introduced. The design of complex dam foundation vibro-stone pile treatment aims to select adaptive design parameters according to the dam structure, reinforcement objectives and geological characteristics. The overall logic is as follows: Figure 1 According to different ground conditions, the ground treated by vibro-stone piles can be roughly divided into three categories: shallow soft soil, deep soft soil and liquefied sand.

[0032] 1) Overall analysis of dam body and foundation. Vibro-stone piles are mostly used for the foundation treatment of earth-rock dams or earth-rock cofferdams. The treatment objectives can be summarized as settlement control, anti-sliding stability, and anti-liquefaction. Settlement control indicators can be divided into two categories: total settlement and uneven settlement. Total settlement is generally characterized by the ratio of total settlement to dam height. According to experience, when the ratio is less than 1%, the dam body has fewer cracks, and when the ratio is greater than 3%, the dam body has more cracks; uneven settlement is often evaluated using the deformation inclination method. The deformation inclination refers to the ratio of the settlement difference between two points to their horizontal distance. 1% can be taken as the critical deformation inclination. Anti-sliding stability is generally characterized by the anti-sliding safety factor, which can be calculated using the simplified Bishop method, the Morgenstern-Price method, and other methods. Depending on the level and working conditions of the dam, the safety factor is between 1.10 and 1.50. Earthquake liquefaction is often identified using the theoretical framework established by Seed, which is based on the relationship between the seismic shear stress ratio (CSR) and the liquefaction resistance of sand (CRR). In field applications, indicators such as the shear wave velocity method and the standard penetration critical number (SPT) can be used as the basis for judgment.

[0033] 2) Composite foundation index requirements. Since the mechanical parameters of soil and the deformation and stability of composite foundation have a highly nonlinear relationship, it is difficult to directly give the mechanical parameter requirements of composite foundation through simple formulas. During design, the initial value of the replacement rate m can be given by formula (1), and then deformation, anti-sliding stability and seepage analysis can be performed through finite element calculation. The finite element calculation parameters can be calculated by formula (2), and the replacement rate m is fed back based on the calculation results. Before formal construction, production tests should be carried out to further verify the feasibility of the design scheme.

[0034]

[0035] X=mX p +(1-m)X s #(2)

[0036] Where: m is the replacement rate; f spk is the characteristic value of the bearing capacity of the composite foundation; f sk is the characteristic value of soil bearing capacity between piles; f pk is the characteristic value of pile bearing capacity; X is the composite foundation simulation calculation parameter; X p and X s are the simulation calculation parameters for pile body and soil between piles respectively.

[0037] 3) Determine the design parameters of the gravel pile. The pile parameters that need to be paid attention to in the design of gravel pile dam foundation include the treatment depth D p, pile diameter d0, replacement rate m and pile layout form. The treatment depth needs to be determined by comprehensively considering the characteristics of the stratum to be treated and the construction capacity of the equipment. In the past, the maximum depth of vibro-replacement gravel piles for treating complex dam foundations did not exceed 35m. The treatment depth of Lawa Hydropower Station has exceeded 68m, but it still lacks standardization. The pile diameter is mostly 1.0-1.2m. The designed pile diameter of the vibro-replacement gravel piles of the Hard Liangbao Hydropower Station reaches 1.3m, which is the largest in the surveyed project, but the requirements for construction equipment and construction parameters are relatively strict. The replacement rate is calculated according to formula (1) and verified by calculation or test. In order to significantly improve the bearing capacity of the gravel pile treatment foundation, an area replacement rate of 0.25 or greater is required.

[0038] Based on the above basic knowledge, Figure 2 FIG. 1 is a flow chart of a method for determining design parameters of an intelligent vibro-stone pile provided by an embodiment of the present invention. Figure 2 As shown, the method specifically includes:

[0039] S110, the pile spacing S p , misalignment angle θ and spacing ratio η are used as characterization parameters of the pile arrangement pattern, where the misalignment angle refers to the angle between two adjacent rows of gravel piles, and the spacing ratio refers to the ratio of the pile spacing to the pile row spacing.

[0040] Figure 3 is a schematic diagram representing the pile arrangement mode (i.e., pile layout mode). In this embodiment, S p , S r , θ represent the pile spacing, pile row spacing and staggered angle, and define the pile spacing ratio S p The unique triangle O1O2O3 (hereinafter referred to as △O1O2O3) determined by , η, θ is the smallest unit constituting the pile plane. Among them, O2 and O3 represent the centers of two adjacent gravel piles in the same row, and O1 represents the center of another gravel pile in the adjacent row projected along the direction of O2O3 between the two adjacent gravel piles, and ∠O1O2O3 is the misalignment angle. Rectangular pile layout, square pile layout, and equilateral triangle pile layout are θ=90°, θ=90° and η=1, θ=60° and special circumstances.

[0041] S120, the maximum distance d between the soil between the piles and the nearest gravel pile s , as an evaluation index for pile arrangement pattern.

[0042] In order to quantitatively evaluate the influence of pile arrangement pattern and the optimal shape, this embodiment uses the maximum value d of the distance between the soil between piles and the nearest gravel pile as the s As an evaluation index of pile layout mode, the best pile layout mode is determined. s It is the main factor affecting the compaction and vibration of soil during construction, as well as the drainage, consolidation and dissipation of pore pressure between piles during operation.s The smaller it is, the greater the compaction or vibration effect of the vibrator on the soil during the construction period and the shorter the drainage path of the soil between piles during the operation period.

[0043] S130. According to the definition of the evaluation index, convert the evaluation index into a function related to the characterization parameter.

[0044] Based on the above triangle △O1O2O3, the evaluation index is defined as:

[0045] d s =max(min(d(s,p)|p∈{O1,O2,O3)})|s∈△O1O2O3) (3)

[0046] Where: max and min are the maximum and minimum value functions respectively; s is the soil position, d(s,p) is the horizontal distance from the soil to the pile;

[0047] According to d s The definition of and the properties of the triangle, the operation of using the above characterization parameters to represent the evaluation index can include the following two cases:

[0048] Case 1: When △O1O2O3 is an acute triangle or a right triangle, d s Equal to the radius of its circumcircle Therefore, d s It is expressed as the following function, called the first function:

[0049]

[0050] Case 2: When △O1O2O3 is an obtuse triangle ( In △O1O2O3, only ∠O1 may be an obtuse angle). s Equal to the radius of the circumscribed circle of △O1O2O4 and the radius of the circumscribed circle of △O1O3O4 The larger value of d s It is expressed as the following function, called the second function:

[0051]

[0052] S140. According to the function, find the value of the characterization parameter when the evaluation index is minimum.

[0053] It can be seen that the first function and the second function include S p , θ and η are three independent variables. In order to determine the best parameter combination, this embodiment gradually reduces the number of independent variables in the above function based on the known quantities that can be obtained in the design of gravel columns. Finally, d s Expressed as a function of a single independent variable, it is possible to determine thes The smallest optimal parameter combination.

[0054] In a specific implementation, the above process may include the following steps:

[0055] Step 1: Consider the pile spacing in the function as fixed, and find the conditions that the staggered angle and the row spacing ratio should satisfy when the evaluation index is minimum. Specifically, Figure 3 It can be seen that the range of values ​​of η and θ is η∈(0,+∞), corresponding to The following discussion is classified according to the value of η:

[0056] 1) When η≤2, △O102O3 is an acute triangle or a right triangle. According to (4), and Since the cosine function is It is monotonically decreasing, so the minimum value of θ-arctan(η-cotθ) is d s Take the minimum value. Let f(θ) = θ-arctan(η-cotθ),

[0057] From f'(θ)=0, we can get: And when When f'(θ)<0, f(θ) decreases monotonically; when When f'(θ)>0, f(θ) increases monotonically. Therefore, When f(θ) takes the minimum value, d s Take the minimum value

[0058] 2) When η>2, △O1O2O3 may be an obtuse triangle. In this case, d in formula (5) s include and Two items. For the first item Its minimum value is For the second item When △O1O2O3 is an obtuse triangle, θ-arctan(η-cotθ)<0, we can also discuss it in different cases:

[0059] ① hour:

[0060] sin 2θ≤sin 2[arctan(η-cotθ)] if and only if Take the equal sign. According to θ-arctan(η-cotθ)<0, at this time It decreases monotonically with θ.

[0061] ② hour:

[0062] sin 2θ>sin 2[arctan(η-cotθ)]. According to θ-arctan(η-cotη)<0, at this time Monotonically increasing with arctan(-cotθ).

[0063] ③Let g(θ)=θ+arctan(η-cotθ), g(θ) increases monotonically with θ.

[0064] Combining ①②③, we can know that when When hour, Take the minimum value and

[0065] That is to say, if the pile spacing in the function is considered fixed, in order to minimize the evaluation index, the ratio of the staggered angle to the row spacing should meet the following conditions: Figure 4 Shows S p When (take S p =1) The offset angle θ and the ratio of the spacing between rows η to d s The impact of Figure 4 It can be seen that for any determined S p ,when d s Take the minimum value,

[0066] Step 2: According to the conditions and functions, convert the evaluation index into a third function related to the pile spacing and the ratio of the pile spacing to the row spacing.

[0067] Under the above conditions In the following, △O1O2O3 is an isosceles triangle with O2O3 as the base, and equations (4) and (5) can be simplified to:

[0068]

[0069] The number of independent variables in function (6) has been reduced to 2, and this function is referred to as the third function in this embodiment.

[0070] Step three: according to the third function and the formula for calculating the substitution rate through the characterization parameters, convert the evaluation index into a fourth function about the spacing ratio.

[0071] based on Figure 3For the pile arrangement mode shown, the relationship between the replacement rate m and the pile arrangement parameters is:

[0072]

[0073] It can be seen that the replacement rate m is not affected by the misalignment angle θ, but only by the pile spacing S. p It is related to the spacing ratio η. The coefficient on the denominator is This is the coefficient in the calculation formula for the equivalent influence circle diameter for square and rectangular pile arrangements in the specification.

[0074] From formula (7), we can get: Substituting into formula (6) we can get:

[0075]

[0076] Since m can be predetermined by (1), only one independent variable η remains in function (8). In this embodiment, function (8) is referred to as the fourth function.

[0077] Step 4: Determine the optimal value of the spacing ratio when the evaluation index is minimized according to the fourth function.

[0078] The fourth function (8) can be transformed into:

[0079]

[0080] According to the mean inequality, we know that:

[0081] If and only if When the equal sign is taken, Conforms to the value range.

[0082] If and only if When the equal sign is taken, Conforms to the value range.

[0083] To sum up, when or When s Take the minimum value At this time, η is the optimal value of the row spacing ratio. When △O1O2O3 is an equilateral triangle, when When △O1O2O4 is an equilateral triangle, it is rotated 90° clockwise to Therefore, from the perspective of soil compaction and vibration during construction, and drainage, consolidation and pore pressure dissipation between piles during operation, the equilateral triangle arrangement can achieve the best engineering treatment effect and is the optimal pile arrangement mode.

[0084] Based on the above optimal spacing ratio and optimal pile layout, in actual engineering design, the characteristic value of the composite foundation bearing capacity f can be determined by survey data. spk , characteristic value of soil bearing capacity between piles f sk and the characteristic value of pile bearing capacity f pk ; Determine the pile diameter value d0 based on experience or other methods.

[0085] Then, f spk 、f sk and f pk Substitute into formula (1) and calculate the substitution rate value m.

[0086] Then the replacement rate value m, pile diameter value d0 and the optimal value of the spacing ratio are or Substitute into the following formula (7) to determine the pile spacing value S p ; The pile spacing value S p and the optimal value η of the spacing ratio, substitute into the definition of the spacing ratio Determine the pile spacing value S r .

[0087] At the same time, when the optimal value of the spacing ratio is substituted into the maximum value of the distance between the soil between the piles and the nearest gravel pile, the conditions that the offset angle θ and the spacing ratio should satisfy are: Determine the misalignment angle value θ.

[0088] Pile spacing value S p , row spacing value S r Once the value of the offset angle θ is determined, the maximum distance d between the soil between the piles and the nearest gravel pile is determined. s The optimal pile layout mode with the smallest amount of time.

[0089] In summary, the embodiment of the present invention provides a method for determining design parameters of intelligent vibro-replacement gravel piles, which introduces the misalignment angle θ and the spacing ratio η as the characterization parameters of the pile arrangement mode, and takes the maximum value d of the distance between the soil between the piles and the nearest gravel pile as the optimal value. s The optimal characterization parameter and pile arrangement pattern are determined as evaluation indicators of the pile arrangement pattern. In particular, according to the nature of the pile arrangement pattern shown by the pile arrangement, the present embodiment provides the relationship between the replacement rate m and the pile arrangement parameters, and uses the relationship to solve the optimal spacing ratio; compared with directly providing the optimal pile spacing and pile row spacing, the optimal spacing ratio allows the pile spacing and pile row spacing to be flexibly selected, and has a stronger fault tolerance.
