Description

Technical Field

[0001] This application relates to the field of submarine cable engineering technology, and in particular to a method, apparatus, equipment and storage medium for evaluating the anti-slip properties of concrete interlocking channels. Background Technology

[0002] Submarine cables are used in various fields such as power transmission and communications. With the continuous growth of marine renewable resource development and the increasing demand for cross-sea communications, the laying and maintenance of submarine cables has become an important issue in the field of marine engineering. Submarine cable safety faces many challenges in the complex marine environment, among which seabed erosion is a key problem. In areas prone to seabed erosion, the water flow velocity is high and the direction is variable, causing sediment and other materials on the seabed surface to be washed away and transported. In such an environment, cables that are originally buried under the seabed may become exposed or suspended, greatly increasing the risk of damage from trawlers, anchors, and other sources.

[0003] To ensure the safety of submarine cables on easily eroded seabeds, protective measures are commonly employed, such as laying concrete interlocking barriers above the buried cables. These barriers limit seabed erosion above the cables and provide some protection. However, traditional assessment methods have limitations in evaluating the stability of these barriers. These methods often focus only on the structural strength of the barriers themselves and the friction with the seabed, neglecting the influence of complex factors such as seabed and barrier deformation and water flow changes under erosion. Therefore, existing methods cannot comprehensively and accurately assess the anti-slip stability of concrete interlocking barriers on easily eroded seabeds, thus failing to guarantee the effectiveness and durability of submarine cable protection.

[0053] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0054] For easier understanding, please refer to Figure 1 An embodiment of a concrete interlocking drain anti-slip assessment method provided in this application includes:

[0055] Step 101: Obtain the settlement of the concrete interlocking drain under different scouring modes, including edge scouring and suction scouring.

[0056] Further, step 101 includes:

[0057] The first subsidence under the edge scour mode is calculated based on the preset thickness of the concrete interlocking column;

[0058] The number of Shields is calculated based on the average diameter of a single concrete block and the median particle size of the sediment seabed.

[0059] Calculate the second subsidence amount under the suction flushing mode based on the Shields number;

[0060] The first and second subsidence amounts constitute the subsidence amount.

[0061] It should be noted that the scouring patterns of concrete interlocking flushes include two types: one is edge scouring, where the edge of the flushing flush on the upstream side sinks or rolls up; please refer to [link to relevant documentation]. Figure 3 One method involves suction flushing, where the sediment below flows out through the gaps in the interlocking system, causing the entire system to sink. Please refer to [link to relevant documentation]. Figure 4 Different scour modes require different methods to obtain the settlement of the concrete interlocking channels. In the edge scour mode, different interlocking channel thicknesses (i.e., preset thicknesses) can be used for trial calculations. The calculated settlement results are then compared and analyzed to find the result that matches the project's expectations as the settlement amount for the edge scour mode. Multiple preset thicknesses can be selected, and can be set according to actual needs, such as 0, 0.5, 1, etc.

[0062] For the suction-flushing scour mode, the Shields number can be calculated based on the average diameter of a single concrete block and the median particle size of the sediment bed. The Shields number is a dimensionless number in river dynamics that characterizes the ratio of flow shear force to sediment gravity. It is derived from the ratio of the shear stress exerted by the flow on the bed surface to the underwater gravity of the bed sediment and is used to describe the sediment initiation conditions. The Shields number is specifically defined as follows:

[0063]

[0064] in, For friction speed, Represents gravitational acceleration. The median grain size of the sedimentary seabed. Specific gravity of the particles. Friction speed. It is a straight line that is formed by measuring velocity profiles, plotting multiple data points on semi-logarithmic graph paper, and then fitting them together.

[0065] In this embodiment, the critical number of Shields in the suction flushing mode is... It can be calculated as follows:

[0066]

[0067] in, It represents the average diameter of a single concrete block in a concrete interlocking structure.

[0068] when At this time, the seabed will be disturbed, which will cause the concrete interlocking embankment to sink. After sinking to a certain extent, it will reach equilibrium, and the amount of sinking will be... The relationship with the number of Shields is expressed as follows:

[0069]

[0070] Step 102: Calculate the flow forces under different scouring modes based on the subsidence and the baseline hydrodynamics.

[0071] Further, step 102 includes:

[0072] The reduction factor for the interlocking concrete flow is calculated based on the settlement and the average diameter of a single concrete block.

[0073] The flow forces under different scouring modes are calculated based on the reduction factor, the baseline hydrodynamic force, and the number of interlocking discharges.

[0074] Furthermore, step 102, preceding the following, also includes:

[0075] The drag force, inertial force, and lift of the concrete interlocking chute in the horizontal direction are calculated based on the cross-sectional area, maximum projected area, and submerged volume of the concrete interlocking chute on the flat seabed, thus obtaining the reference hydrodynamic force.

[0076] Please refer to the stress analysis of the concrete interlocking keel on the leveled seabed in this embodiment. Figure 5 Based on the cross-sectional area of ​​the concrete interlocking drain front surface Maximum projected area and immersion volume The horizontal drag force of the interlocking concrete can be calculated separately. Inertial force and lift :

[0077]

[0078]

[0079]

[0080] in, Indicates the density of seawater. , These represent the unidirectional flow velocity at the top of the concrete interlocking drain and the velocity amplitude caused by waves, respectively. , These represent the drag force coefficient and lift force coefficient of the concrete interlocking system, respectively. Indicates the inertial force coefficient. Indicates time.

[0081] Then we can analyze the hydrodynamic changes of the interlocking concrete drain after scouring, and refer to the force analysis for details. Figure 6 First, it can be determined based on the amount of sinking. and the average diameter of a single concrete block Calculate the reduction factor for the interlocking concrete stack:

[0082]

[0083]

[0084] in, , These represent the reduction factors in the horizontal and vertical directions, respectively.

[0085] A detailed analysis of the hydrodynamic changes under the edge scour mode reveals that the first row of interlocking concrete canopies on the upstream side is directly affected. Assuming the number of interlocking concrete canopies is N, the hydrodynamic force borne by the first row on the upstream side is that of the entire interlocking canopy. Based on the reduction factor , benchmark hydrodynamics , , The edge flow force information can be calculated from the number of interlocking rows N, specifically expressed as:

[0086]

[0087]

[0088]

[0089]

[0090]

[0091]

[0092] in, , , These represent the drag force, inertial force, and lift of the entire interlocking conveyor after hydrodynamic reduction under edge scouring conditions. , , These represent the drag force, inertial force, and lift of the first interlocking row on the upstream side after hydrodynamic reduction under edge scouring conditions.

[0093] Analyzing the hydrodynamic changes under the suction-flushing mode, the suction-flushing affects the overall stress on the interlocking pump. The calculation method after hydrodynamic reduction is as follows:

[0094]

[0095]

[0096]

[0097] Step 103: Calculate the lateral resistance of the seabed to the concrete interlocking sluice under different scour modes based on the subsidence and flow forces. The lateral resistance includes friction and residual soil resistance.

[0098] Further, step 103 includes:

[0099] Friction force is calculated based on flow action force, friction coefficient, and buoyancy of concrete interlocking slabs;

[0100] The soil discharge pressure ratio under different scouring modes is calculated based on the flow force, the underwater weight of the seabed soil, and the underwater weight of the interlocking drainage.

[0101] The residual soil resistance under different scour modes was calculated based on the soil displacement pressure ratio, the underwater weight of the seabed soil, and the settlement.

[0102] The lateral resistance of the seabed to the concrete interlocking embankment is obtained by calculating the sum of frictional force and residual soil resistance.

[0103] It should be noted that the concrete interlocking drain in this embodiment originates from the lateral resistance of the soil. This mainly includes frictional forces from the soil. and residual soil resistance caused by scouring :

[0104]

[0105] Among them, friction It can be calculated using Coulomb's law:

[0106]

[0107] in, The coefficient of friction between the concrete interlocking raft and the seabed. For the floating weight of the concrete interlocking pump, This refers to the vertical lift force of the interlocking concrete flow in either the edge flushing mode or the suction flushing mode.

[0108] The calculation process for residual soil resistance is as follows:

[0109]

[0110] in, This represents the underwater weight of a unit volume of soil. This represents the ratio of soil specific gravity to the interlocking soil discharge normal pressure, i.e., the soil discharge pressure ratio, which is obtained using different calculation methods under different scouring modes.

[0111] If it is edge flushing mode, then The calculation process is as follows:

[0112]

[0113] in, This indicates the weight of the interlocking drainage under the first row of interlocking drains on the flow-facing side. This indicates the lift of the first row of interlocking columns on the upstream side after hydrodynamic reduction under edge scouring conditions.

[0114] If it is in suction flushing mode, then The calculation process is as follows:

[0115]

[0116] in, This indicates the weight of the entire interlocking drain under the interlocking system.

[0117] Step 104: Calculate the safety factor of the concrete interlocking drain for anti-slip based on the lateral resistance and flow force, and conduct anti-slip assessment analysis to obtain the assessment results.

[0118] The safety factor is calculated in this embodiment as follows:

[0119]

[0120] Based on the above safety factor, the anti-slip performance of concrete interlocking manholes can be more accurately controlled during the engineering design stage. The size, shape, weight and other parameters of the interlocking manholes can be adjusted according to the evaluation results, thereby directly improving the stability of the interlocking manholes.

[0121] It can be observed that this embodiment, by considering the hydrodynamic reduction caused by the scouring of the concrete interlocking sluices and the lateral resistance changes caused by the sinking of the interlocking sluices at both ends under scouring, can more accurately assess the anti-slip stability of the concrete interlocking sluices on easily scourable seabeds. This helps ensure the long-term stability of submarine cables on easily scourable seabeds, reducing the risk of cable displacement, suspension, or even breakage due to scouring. By improving the stability and safety of submarine cables, maintenance and repair work caused by cable failures can be reduced, thereby lowering maintenance costs. This not only improves the operational efficiency of submarine cables but also extends their service life.

[0122] The concrete interlocking sluice gate anti-slip assessment method provided in this application fully analyzes the settlement and flow force changes of the concrete interlocking sluice gate under different scouring modes, thereby calculating the lateral resistance of the interlocking sluice gate under different scouring conditions. The lateral resistance includes not only frictional force but also residual soil resistance. This process comprehensively considers the influence of various complex factors on the concrete interlocking sluice gate during seawater scouring, ensuring that the assessment criteria are more consistent with actual conditions and the assessment results are more accurate and reliable. Therefore, this application embodiment can solve the technical problem of existing technologies that only focus on the structural strength of the concrete interlocking sluice gate and the frictional force with the seabed, while ignoring the influence of complex factors such as seabed and interlocking sluice gate deformation and flow force changes under scouring, leading to a lack of accuracy in the assessment of concrete interlocking sluice gate anti-slip.
