[0152] In an embodiment of the present application, a dynamic balance relationship is fixed; based on the dynamic balance relationship, a dynamic balance among horizontal force balance parameters, vertical force balance parameters and moment balance parameters is constructed, thereby ensuring the dynamic balance of the barrel-type foundation structure relative to the water surface.

[0153] At this time, if at least one of the horizontal force balance parameters, vertical force balance parameters and moment balance parameters changes, the remaining two parameters are regulated based on the dynamic balance relationship; the dynamic adjustment of the horizontal force balance parameters, vertical force balance parameters and moment balance parameters is triggered based on the dynamic balance relationship.

[0154] S16: monitor the inclination of the bucket-type foundation structure in real time, and dynamically adjust the dynamic balance relationship according to the inclination of the bucket-type foundation structure;

[0155] In the specific implementation process of the present invention, the specific steps may be:

[0156] S161: Real-time monitoring of the movement of the barrel-type foundation structure relative to the water surface;

[0157] S162: real-time collection of the inclination of the bucket-type foundation structure relative to the water surface;

[0158] S163: Tilt degree of freeze frame;

[0159] S164: matching the corresponding overall inclination based on the inclination degree;

[0160] S165: defining a dynamic balance relationship based on the overall inclination and the corresponding relationship table. At this time, the dynamic balance relationship is a variable parameter and changes dynamically according to the change of the overall inclination.

[0161] In an embodiment of the present application, horizontal force balance parameters, vertical force balance parameters and moment balance parameters are associated with a dynamic balance relationship; dynamic adjustment of the horizontal force balance parameters, vertical force balance parameters and moment balance parameters is triggered according to the dynamic balance relationship; the inclination degree of the barrel-type foundation structure is monitored in real time, and the dynamic balance relationship is dynamically regulated according to the inclination degree of the barrel-type foundation structure, so as to make corresponding dynamic adjustments according to different inclination degrees, thereby improving the dynamic stability of the barrel-type foundation structure in a floating state.

[0162] At this time, the activity of the bucket-type foundation structure relative to the water surface is monitored in real time so as to collect parameters of the bucket-type foundation structure. At the same time, the inclination degree of the bucket-type foundation structure relative to the water surface is collected in real time so as to introduce the inclination degree of the bucket-type foundation structure relative to the water surface, thereby controlling the inclination degree of the bucket-type foundation structure relative to the water surface.

[0163] Therefore, the degree of inclination is fixed; the degree of inclination based on matches the corresponding overall inclination; the dynamic balance relationship is defined based on the overall inclination and the corresponding relationship table. At this time, the dynamic balance relationship is a variable parameter and changes dynamically according to the change of the overall inclination.

[0164] Basic assumptions and provisions:

[0165] The assumptions for the foundation stability analysis of the barrel foundation structure during air flotation transportation, taking into account water flow and lifting force, are as follows:

[0166] 1) Only the influence of hanging force, water flow, foundation deadweight, buoyancy and horizontal cables on the floating state of the bucket foundation structure is considered, and the influence of environmental loads such as wind and waves is not considered;

[0167] 2) The effect of the exhaust sinking of the barrel-type foundation structure on the gas volume and pressure in the barrel is not considered, and the analysis is only performed under the conditions of given freeboard height and gas volume;

[0168] 3) During the air flotation transportation of the barrel-type foundation structure, the top cover of the lower barrel is never submerged;

[0169] 4) The center of gravity of the foundation is above the center of buoyancy. The foundation rotates with the center of buoyancy as the center and swings at a small angle. The bottom water in the barrel foundation structure can form an effective seal.

[0170] 5) The dynamic process during the reciprocating swing of the foundation is not considered, and only static analysis is performed on a given state;

[0171] 6) The gas state conversion time is negligible and it directly converts from one state to another;

[0172] 7) The gas pressure in all directions in the barrel foundation structure is the same, and the internal water level surface is always flat;

[0173] 8) The angle between the front and rear hooks and the top cover of the bucket-type base structure does not change as the bucket-type base structure tilts;

[0174] 9) The sum of the total buoyancy and the total lifting force of the bucket foundation structure remains unchanged, that is, the deadweight of the bucket foundation structure.

[0175] The long side of the bucket-type foundation structure has the largest frontal flow area and is the most unfavorable, so the bucket-type foundation structure under the condition of frontal flow on the long side of the bucket-type foundation structure is taken as the research object; where θ is the inclination angle of the bucket-type foundation structure, unit: °; F 重 F is the gravity on the barrel foundation structure, in kN; 浮 F is the buoyancy of the barrel foundation structure, in kN; 水 It is the water flow force on the barrel foundation structure, unit is kN.

[0176] From the horizontal force balance we can get:

[0177] F 水 -F 拉 cosβ+F 吊1 cos(α1+θ)-F 吊2 cos(α2-θ)=0(1)

[0178] From the vertical force balance we can get:

[0179] F 浮 +F 吊1 sin(α1+θ)+F 吊2 sin(α2-θ)-F 重 =0(2)

[0180] Take θ=20°, α1=α2=80°; then sin(α1+θ)=0.9848≈1.0, sin(α-θ)=0.8660≈1.0.

[0181] The vertical force balance can be simplified as:

[0182] F 浮 +F 吊1 +F吊2 -F 重 =0(3)

[0183] Take F 拉 With F 吊1 The same position of the action point has limited influence on the moment balance calculation. Taking the rear hook (close to the crane ship) as the center point to take the moment balance, we can get:

[0184]

[0185] As above, we take sin(α1+θ)≈1.0 and sin(α-θ)≈1.0, then equation (4) can be simplified to:

[0186]

[0187] Among them, F 吊1 The lifting force provided by the rear hook to the bucket foundation (the sum of the lifting forces of the two rear hooks), unit kN; F 吊2 The lifting force provided by the front hook to the bucket foundation (the sum of the lifting forces of the two front hooks), unit kN; F 拉 is the total tension provided by the horizontal cable to the bucket foundation, in kN; H is the height of the lower bucket, in m; h 水 h is the height of the water flow force acting point, in meters, with the bucket end as the 0 point, and is assumed to be half the height of the lower bucket; G h is the center of gravity height of the bucket foundation structure, in meters, with the bucket end as the 0 point; c0 is the initial buoyancy center height at a given freeboard height, in m, with the barrel end as the 0 point; M L is the section resistance moment of the barrel section along the short side of the barrel foundation structure, unit: m 4 , the direction of action is opposite to the rotation direction of the barrel foundation structure, and plays a restoring role; M I =∑i is the sum of the cross-sectional resistance moments i of each small compartment in the lower barrel along the short side direction, in m 4 , the direction of action is the same as the rotation direction of the barrel-type foundation structure, which plays a role in intensifying the rotation; γ w is the water body density, unit is kN / m 3 .

[0188] In summary, we get three independent equations for vertical force balance, horizontal force balance and moment balance. There is a unique solution only when there are three unknowns. The following is an analysis of the known conditions and the situation with unknowns. 重 Generally, it can be obtained according to the drawings, which is a known condition; the height H of the lower bucket can generally be determined according to the drawings, which is a known condition; the height h of the water flow force point 水 , assuming it is half of the lower bucket height H, which is a known condition; the center of gravity height of the bucket foundation structure h GIt can be obtained according to the drawings, which is a known condition; the average freeboard height h0 of the barrel-type foundation structure during air flotation transportation is pre-calculated during construction and controlled by the first exhaust diving height, which is a known condition; the initial buoyancy center height h under a given freeboard height h0 c0 , which can be determined through conventional floating stability analysis and is a known condition; the section resistance moment M of the barrel section along the short side of the barrel foundation structure L It can be obtained according to the drawings, which is a known condition; the sum of the cross-sectional resistance moments of each small compartment of the lower barrel along the short side direction is M I It can be obtained according to the drawings, which is a known condition; water flow force F 水 It can be calculated based on the assumed flow rate, F 水 =0.5γ w v 2 A, where v is the flow velocity in m / s, determined by the assumption, is a known condition, and A is the flow area in m 2 , which can be calculated based on the size of the barrel foundation structure and the average freeboard height h0. As the conditions are known, the water flow force F 水 It is also a known condition; the angle α1 between the front main hook sling and the lower barrel top cover and the angle α2 between the rear main hook sling and the lower barrel top cover can be determined according to the hook position, lifting height, boom angle and lug position, which are known conditions; β is the angle between the horizontal cable and the horizontal plane, which can be determined according to the ship's draft, anchor machine position and pull ring position, which is a known condition.

[0189] The sum of the lifting forces provided by the two front main hooks to the bucket-type foundation structure is F 吊2 , the sum of the lifting forces provided by the two rear main hooks to the bucket foundation structure is F 吊1 , the sum of the tension provided by the two horizontal cables to the barrel foundation structure is F 拉 The inclination angle θ of the bucket-type foundation structure after reaching equilibrium under the above action is the unknown quantity to be solved. In summary, there are 3 independent equations and 4 unknown quantities to be solved. The solution is not unique, so the optimization method is used to solve it. The optimization solution algorithm is as follows: first, input all known quantities; input optimization parameters such as the unknown quantity variation range, solution accuracy, discrete space size and initial value of unknown quantity, and input the initial value combination of unknown quantities into the left side of equation (1) and equation (5) respectively. Theoretically, when the bucket-type foundation structure is subjected to force and moment balance, the calculation results on the left side of equation (1) and equation (5) are both 0. Therefore, the criterion of |Equation (1)|+|Equation (5)| approaching 0 is used. If it is satisfied, the search is terminated. Otherwise, it is adjusted to the unknown quantity combination based on the previous unknown quantity combination, and |Equation (1)|+|Equation (5)| is calculated repeatedly until the error standard is met.

[0191] The dimensioning unit of the barrel foundation structure is mm, among which, the total height of the barrel foundation structure is 31.5m, the total weight is 5111.650t, the upper barrel is 17.5m, the lower barrel is 14.0m, the lower barrel is divided into 15 chambers, the foundation center of gravity height hG = 11.848m; the center of gravity height hG = 11.848m; the length, width and height of the upper barrel are 7.2m, 20.0m and 17.5m respectively; the length, width and height of the lower barrel are 40.0m, 20.0m and 14.0m respectively. The calculation results of the horizontal section moments of the barrel foundation structure are shown in Table 1. The sum of the total hoisting force (F hoist 1 + F hoist 2) is 100~600t. Under the condition of freeboard h0 = 1.5m, the initial buoyancy center height hc0 = 8.813~9.044m. The angle between the front main hook sling and the lower barrel top cover, and the angle between the rear main hook sling and the lower barrel top cover are α1=α2=79°, and the plane distance from the lifting ear to the central axis of the barrel foundation structure is LT=9.268m.

[0193]

[0194] Tables 2 to 4 show the results of the lifting force distribution, horizontal cable tension and foundation inclination under different combinations of water flow velocities and total lifting forces.

[0198]

[0199]

[0200] Table 4 Results of lifting force, figure eight cable and foundation inclination at flow velocity of 1.5 m / s

[0201]

[0202] The results in Tables 2 to 4 show that the absolute values ​​of the results of formula (1) are all less than 10 kN, and the absolute values ​​of the results of formula (5) are all less than 5 kN·m, which means that the given analysis results can satisfy the force balance and moment balance and are in a stable state. Under the action of 1.5 m / s water flow, the horizontal component force F of the horizontal cable tension within the analysis range is 拉 cosβ decreases with the increase of total lifting force, and the foundation inclination angle θ increases with the increase of total lifting force. The main lifting force is borne by the front hook. Under the action of 2.0m / s water flow, the horizontal component force F of the horizontal cable tension within the analysis range 拉cosβ increases first and then decreases with the total suspension force and increases and decreases repeatedly. The foundation inclination angle θ and the horizontal component force F of the horizontal cable tension 拉 cosβ changes inversely, F 拉 As F increases, the inclination angle θ decreases, and vice versa. 拉减小 The inclination angle θ increases. When the inclination angle θ is small, the lifting force borne by the rear hook exceeds 50%. When the inclination angle θ is large, the main lifting force is borne by the front hook.

[0203] Under the action of 2.5m / s water flow, the horizontal component of the cable tension within the analysis range is F 拉 cosβ increases first and then decreases with the total suspension force and increases and decreases repeatedly. The foundation inclination angle θ and the horizontal component force F of the horizontal cable tension 拉 cosβ changes inversely, F 拉 As F increases, the inclination angle θ decreases, and vice versa. 拉减小 The inclination angle θ increases. When the inclination angle θ is small, the lifting force borne by the rear hook exceeds 50%. When the inclination angle θ is large, the main lifting force is borne by the front hook. It should be pointed out that under the same lifting force conditions, the horizontal component of the horizontal cable tension increases significantly with the flow velocity. When the flow velocity is 2.0m / s, it can reach 1000~1200kN under the condition of small inclination angle. When the flow velocity is 2.5m / s, it can reach 1800~2000kN under the condition of small inclination angle, which may cause the horizontal cable to break. Therefore, it is necessary to comprehensively control the lifting force, cable tension and foundation inclination during the air flotation transportation of the barrel-type foundation structure to ensure the safety and reliability of the air flotation transportation process.

[0204] In an embodiment of the present invention, through the method in the embodiment of the present invention, the current position and the water area position of the bucket-type foundation structure are collected, and the state of the bucket-type foundation structure relative to the water surface is defined according to the current position and the water surface position of the bucket-type foundation structure; when the state of the bucket-type foundation structure relative to the water surface is a floating state, the bucket-type foundation structure is dragged on the water surface, and multiple dynamic parameters of the bucket-type foundation structure are collected; the horizontal force balance parameters, vertical force balance parameters and moment balance parameters of the bucket-type foundation structure are matched based on multiple dynamic parameters, thereby introducing horizontal force balance parameters, vertical force balance parameters and moment balance parameters, so as to facilitate overall control of the horizontal force balance parameters, vertical force balance parameters and moment balance parameters, thereby ensuring control in the horizontal force balance dimension, the vertical force balance dimension and the moment balance dimension.

[0205] At the same time, the horizontal force balance parameters, vertical force balance parameters and moment balance parameters are associated with the dynamic balance relationship; the dynamic adjustment of the horizontal force balance parameters, vertical force balance parameters and moment balance parameters is triggered according to the dynamic balance relationship; the inclination degree of the bucket-type foundation structure is monitored in real time, and the dynamic balance relationship is dynamically regulated according to the inclination degree of the bucket-type foundation structure, so as to make corresponding dynamic adjustments according to different inclination degrees, thereby improving the dynamic stability of the bucket-type foundation structure in a floating state.
