[0002] As an important support structure for overhead transmission lines, the main function of a guyed tower is to support conductors and lightning conductors and ensure that they meet the clearance requirements for the ground and ground objects. A guyed tower can not only bear the loads of conductors, lightning conductors, and itself, but also bear various external loads, such as wind loads. With the rapid development of the power industry, the demand for guyed towers is increasing continuously, especially in complex and remote areas, the construction of guyed towers is particularly important.

[0003] The analysis of the foundation load capacity of a guyed tower is an important pre-work in the construction of a guyed tower, which directly affects the construction efficiency and engineering quality of the guyed tower. In traditional technologies, the basic principle of analyzing the foundation load capacity of a guyed tower is static equilibrium, that is, all external forces acting on the guyed tower (including the gravity of conductors and lightning conductors, wind loads, forces caused by temperature changes, etc.) reach equilibrium with the reaction force provided by the foundation. By calculating the magnitudes and directions of these external forces, the reaction force required to be provided by the foundation can be determined, thereby evaluating the load capacity of the foundation.

[0064] S100: Obtain the guyed tower mass, the guy wire specification data included in the guyed tower, the dynamic wind load change data during the gantry lifting process, and the actual geotechnical investigation report corresponding to the guyed tower.

[0065] In actual operation, the cable winch pulls the gantry to lift the guyed tower. The total mass of the guyed tower includes the mass of all components such as the tower body, accessories, and possibly pre-installed equipment. Collect the detailed specifications of the guy wires used in the guyed tower, including but not limited to the diameter, material type, tensile strength, etc. of the guy wires. These data will be used for subsequent static load calculations. During the process of the gantry lifting the guyed tower, use meteorological instruments such as anemometers and wind vanes to record meteorological data such as wind speed and wind direction in real time. These data will be used to calculate the dynamic change of the wind load on the guyed tower during lifting. Obtain the geotechnical investigation report of the installation location of the guyed tower. The report should include key information such as the physical and mechanical properties of the soil, the groundwater level, and the foundation bearing capacity. These information will be used to calculate the ground anchor resistance.

[0066] S200: Calculate the static load of the guyed tower according to the guyed tower mass and the guy wire specification data included in the guyed tower.

[0067] Based on the collected data of the guyed tower quality and guy wire specifications, calculate the static load of the guyed tower using the principles of structural mechanics. This includes considering the self-weight of the guyed tower, the supporting effect of the guy wires, and other possible static forces (such as temperature stress, etc.). During the calculation process, a mechanical model of the guyed tower needs to be established and detailed force analysis is carried out based on the model.

[0068] S300: Calculate the dynamic load of the guyed tower according to the quality of the guyed tower and the dynamically changing data of the wind load.

[0069] Combined with the quality of the guyed tower and the collected dynamically changing data of the wind load, calculate the dynamic load of the guyed tower using the principles of dynamics. This includes considering the instantaneous impact force and periodic vibration force generated by the wind load on the guyed tower. During the calculation process, according to meteorological data such as wind speed and wind direction, relevant theories and methods of wind engineering are used to simulate and analyze the dynamic response of the guyed tower under the action of the wind load.

[0070] S400: Calculate the ground anchor resistance of the guyed tower according to the actual geotechnical engineering investigation report.

[0071] According to the collected actual geotechnical engineering investigation report, calculate the ground anchor resistance of the guyed tower using the principles of soil mechanics. This includes considering physical and mechanical properties such as the bearing capacity and shear strength of the soil, as well as factors such as the geometric dimensions and burial depth of the ground anchor. During the calculation process, a model of the interaction between the ground anchor and the soil needs to be established and detailed force analysis is carried out based on the model.

[0072] S500: Based on the static load, dynamic load, and ground anchor resistance, obtain the analysis result of the foundation load force of the guyed tower.

[0073] Integrate the calculation results of the static load, dynamic load, and ground anchor resistance to obtain the analysis result of the foundation load force of the guyed tower. This includes evaluating the stability, deformation conditions, and possible safety risks of the guyed tower under different loading conditions. During the analysis process, detailed interpretation and discussion of the calculation results are required, and corresponding design suggestions and optimization measures are proposed.

[0074] The above-mentioned guyed tower foundation load capacity analysis method obtains the mass of the guyed tower, the guy wire specification data included in the guyed tower, the dynamic wind load change data during the gantry lifting process, and the corresponding actual geotechnical engineering investigation report of the guyed tower; calculates the static load of the guyed tower according to the mass of the guyed tower and the guy wire specification data included in the guyed tower; calculates the dynamic load of the guyed tower according to the mass of the guyed tower and the dynamic wind load change data; calculates the ground anchor resistance of the guyed tower according to the actual geotechnical engineering investigation report; and obtains the analysis result of the foundation load capacity of the guyed tower based on the static load, dynamic load, and ground anchor resistance. During the whole process, by comprehensively considering multi-dimensional data such as the mass of the guyed tower, guy wire specifications, dynamic wind load changes, and the actual geotechnical engineering investigation report, the whole scheme can comprehensively and accurately analyze the foundation load capacity of the guyed tower under different working conditions.

[0075] In one embodiment, as Figure 3 shown, S200 includes:

[0076] S210: Determine the angle and tension magnitude of the guy wires according to the guy wire specification data included in the guyed tower.

[0077] According to the guy wire specification data included in the guyed tower (such as the diameter, material, tensile strength, etc. of the guy wires), combined with the layout method and design requirements of the guy wires, determine the angle between each guy wire and the vertical direction (i.e., the guy wire angle). Using mechanical principles, calculate the tension magnitude of each guy wire according to the material characteristics and specifications of the guy wires, as well as the tension requirements of the guyed tower on the guy wires. This usually needs to consider factors such as the pre-tightening force, working tension, and safety factor of the guy wires.

[0078] S220: Based on the mass of the guyed tower, the angle and tension magnitude of the guy wires, and using trigonometric function relationships, calculate the vertical component force of the guy wires.

[0079] Based on the determined guy wire angle and tension magnitude, use trigonometric function relationships (such as sine or cosine functions) to calculate the vertical component force of each guy wire in the vertical direction. The vertical component force is a key index for the supporting effect of the guy wires on the guyed tower in the vertical direction. For the case of multiple guy wires, it is necessary to calculate the vertical component force of each guy wire separately and consider the interaction and influence between the guy wires. Here, when calculating the static load of the guyed tower, not only the conventional factor of the self-weight of the iron tower itself is considered, but also the influence of the vertical component forces of different specification guy wires (such as the upper layer 2XS - 907 and the lower layer 1XS - 907) on the foundation is carefully analyzed. Through precise mechanical analysis, the tension of the guy wires is decomposed into vertical direction components and incorporated into the total static load calculation. The traditional calculation scheme simply estimates the guy wire tension or ignores its influence on the foundation. Here, the calculation method can more accurately evaluate the actual load borne by the foundation under static conditions and provide a more reliable data basis for foundation design.

[0080] S230: Accumulate the vertical components of the guy wires to obtain the total vertical component of the guy wires.

[0081] Accumulate the vertical components of all the guy wires to obtain the total vertical component of the guy wires. This total represents the total supporting force of all the guy wires on the guyed tower in the vertical direction.

[0082] S240: Obtain the static load of the guyed tower based on the mass of the guyed tower and the total vertical component of the guy wires.

[0083] Based on the mass of the guyed tower and the total vertical component of the guy wires, combined with physical constants such as the acceleration due to gravity, calculate the static load of the guyed tower. The static load is the total gravitational force acting on the guyed tower in the static state, including the weight of the guyed tower itself and the vertical supporting force provided by the guy wires.

[0084] In one of the embodiments, as Figure 3 shown, S300 includes:

[0085] S320: Based on the mass of the guyed tower, obtain the inertial forces during the lifting of the gantry and the lifting and lowering of the guyed tower, where the gantry is used to lift the guyed tower.

[0086] Based on the mass of the guyed tower, use Newton's second law to calculate the inertial forces during the lifting of the gantry and the lifting and lowering of the guyed tower.

[0087] S340: Vectorially superimpose the inertial forces and the dynamic change data of the wind load to obtain the dynamic load of the guyed tower.

[0088] Use the dynamic change data of the wind load, including wind speed, wind direction, etc., recorded in real time by meteorological instruments such as anemometers and wind vanes, to calculate the dynamic stress situation of the guyed tower under the action of the wind load. This usually involves converting the wind speed and wind direction data into mechanical quantities such as wind pressure and wind moment, and then using relevant theories and methods of wind engineering to calculate the dynamic response of the guyed tower under the action of the wind load. Vectorially superimpose the calculated inertial forces and the dynamic change data of the wind load. Here, vectorial superposition means that the directions and magnitudes of the inertial forces and the wind load need to be considered, as well as their mutual interactions and influences. When performing vectorial superposition, it is necessary to ensure that the reference coordinate systems of the inertial forces and the wind load are consistent in order to accurately calculate their resultant force. By vectorially superimposing the inertial forces and the wind load, obtain the total stress situation of the guyed tower in the dynamic environment, that is, the dynamic load. The dynamic load is the total dynamic force acting on the guyed tower under the combined action of the wind load and the inertial forces.

[0089] In one of the embodiments, obtaining the dynamic change data of the wind load includes:

[0090] Step 1: Obtain the dynamic change data of the wind speed in the environment where the guyed tower is located, as well as the windward area and wind resistance coefficient of the guyed tower structure.

[0091] The dynamic wind speed change data can be obtained specifically through sensors or based on the data released by meteorological stations. Specifically, an anemometer can be installed near the guyed tower or at representative locations to record the wind speed data in real time. The anemometer should have high accuracy and stability to ensure the accuracy of the data. If there is a meteorological station nearby, the historical and real-time wind speed data provided by it can be obtained. These data usually have high reliability and reference value.

[0092] Step 2: Obtain the dynamic wind load change data based on the dynamic wind speed change data, the wind-receiving area, and the wind resistance coefficient.

[0093] The wind-receiving area refers to the area of the guyed tower structure that directly bears the wind force under the action of the wind load. This can usually be obtained through CAD drawing software or geometric calculation methods. When calculating, factors such as the shape, size, and wind direction of the guyed tower need to be considered. The wind resistance coefficient (also known as the wind load shape coefficient) is an important parameter reflecting the resistance characteristics of the guyed tower structure under the action of the wind load. It is usually related to factors such as the shape, material, and surface roughness of the guyed tower. The wind resistance coefficient can be determined by referring to relevant codes, standards, or conducting wind tunnel tests. After obtaining the dynamic wind speed change data, the wind-receiving area, and the wind resistance coefficient, the following formula can be used to calculate the dynamic wind load change data: Wind load = Dynamic wind speed change data × Wind pressure coefficient × Wind-receiving area.

[0094] In one of the embodiments, according to the actual geotechnical engineering investigation report, calculating the ground anchor resistance of the guyed tower includes:

[0095] Step 1: According to the actual geotechnical engineering investigation report, obtain the soil-related parameters corresponding to the buried ground anchor. The soil-related parameters include soil layer types, the soil layer depths corresponding to different soil layer types, the standard values of the ultimate side resistance corresponding to different soil layer types, soil density, and soil pull-out angle.

[0096] From the actual geotechnical engineering investigation report, detail the types of each soil layer (such as clay, sand, rock, etc.) and their corresponding soil layer depths. This information is the basis for evaluating the force condition of the ground anchor in the soil. Consult the standard values of the ultimate side resistance corresponding to different soil layer types provided in the report. This value reflects the resistance of the soil to the side wall of the ground anchor and is a key parameter for calculating the ground anchor resistance. Obtain the density data of the soil, which affects the bearing capacity of the soil and the embedding depth of the ground anchor. Understand the soil pull-out angle, which is the angle representing the ability of the soil to resist the pulling out of the ground anchor. This parameter is particularly important for evaluating the force condition of the ground anchor in the vertical direction.

[0097] Step 2: Obtain the ground anchor construction-related parameters corresponding to the ground anchor construction. The ground anchor construction-related parameters include ground anchor type, ground anchor size, and the angle between the ground anchor force direction and the ground.

[0098] Obtain the specific type (such as screw anchor, plate anchor, etc.) and dimensions (such as diameter, length, plate width, etc.) of the ground anchor according to the design drawings or construction records. These information are crucial for calculating the bearing area and shape factor of the ground anchor. Determine the force direction of the ground anchor (usually vertical or inclined) and the angle it makes with the ground. This angle affects the embedment depth and force distribution of the ground anchor in the soil.

[0099] Step 3: Calculate the ground anchor resistance of the guyed tower according to the soil-related parameters and ground anchor construction-related parameters.

[0100] After obtaining the above soil-related parameters and ground anchor construction-related parameters, the following methods can be used to calculate the ground anchor resistance: 1) Side resistance calculation: Calculate the side resistance of the ground anchor in the soil according to the type, dimensions, angle between the force direction and the ground of the ground anchor, and the standard value of the ultimate side resistance of the soil. This usually involves multiplying the bearing area of the ground anchor by the standard value of the ultimate side resistance of the soil and considering the influence of the angle on the force. 2) Comprehensive resistance calculation: Vectorially superimpose the side resistance and end resistance (if applicable) to obtain the total resistance of the ground anchor. This total resistance reflects the ability of the ground anchor to resist external tensile forces in the soil. Consider the safety factor: To improve the conservativeness and safety of the calculation, a safety factor is usually multiplied on the basis of the calculated ground anchor resistance. This safety factor is determined according to engineering experience, design specifications or relevant standards.

[0101] To illustrate the calculation process of the ground anchor resistance in detail, the following will be introduced in detail with specific application examples and specific calculation formulas.

[0130] The design value of the vertical bearing capacity of the foundation pile is R = Qsk / γs + Qpk / γp = 2144.1369495 / 1.67 + 549.778705 / 1.67 = 1612 KN;

[0131] Based on the above calculations, the large plate foundation is designed to be used in combination with cast-in-place piles. The bearing capacity of the entire new foundation is:

[0132] 4 * 1612 + 4681.04 = 11129.07 KN = 1112.907 T.

[0133] In this specific application embodiment, the self-weight of the guyed tower is 164.5 tons, plus the downward pressure of the steel wire rope of 54.63 tons and the weight of the components mounted on the gantry of 42 tons. The total downward pressure of the tower body is 261.13 tons. Through design calculation, the maximum bearing capacity of the new foundation is 1112.907 tons, and the safety factor is 4.26, meeting the construction requirements.

[0134] Check of the burial depth of the ground anchor

[0135] In this specific application embodiment, ground anchors with a specification of 2m * 0.5m are mainly used, equipped with corresponding ground anchor pull rods. The specific calculation of the burial depth is shown in the following formula:

[0136] The calculation formula is as follows:

[0137]

[0138] Among them, VK = [dl + (d + l)htgθ1 + 0.75htg2θ1]h.

[0139] In the formula, QK is the allowable tension of the ground anchor, kN; VK is the volume of soil for the uplift resistance of the ground anchor, m3; h is the burial depth of the ground anchor, m; θ1 is the calculated uplift angle of the soil, (°); γ is the density of the soil, t / m3; a is the angle between the force direction of the ground anchor and the ground (°); K is the safety factor for the uplift resistance of the ground anchor, taken as 2.0; d is the width of the ground anchor, m; l is the length of the ground anchor, m. According to the actual situation of this project and the content in the geotechnical engineering investigation report, the values of the above data are as follows: the uplift angle of the soil θ1 is selected as 25°, the density of the soil γ is 19.2 kN / m3, and the angle a between the force direction of the ground anchor and the ground is 45°. The calculated burial depth of the ground anchor is shown in Table 1 below.

[0143]

[0144] In one embodiment, the analysis results of the foundation load capacity of the guyed tower obtained based on the static load, dynamic load, and ground anchor resistance include:

[0145] Step 1: Obtain the preset partial factor for static load and the preset partial factor for dynamic load.

[0146] The preset partial factor for static load is used to consider the uncertainties of the static load, such as variations in material properties, construction errors, etc. It is usually determined based on engineering experience, design codes, or relevant standards. The preset partial factor for dynamic load is similar to the partial factor for static load. The partial factor for dynamic load is used to consider the uncertainties of the dynamic load, such as fluctuations in wind speed, changes in seismic forces, etc. This factor is also determined based on engineering experience, design codes, or relevant standards.

[0147] Step 2: Based on the preset partial factor for static load, the preset partial factor for dynamic load, as well as the static load and dynamic load, calculate the design load by weighted summation.

[0148] Multiply the static load by the partial factor for static load to obtain the design value of the static load. This design value reflects the actual effect of the static load on the guyed tower foundation after considering the uncertainty factors. Similarly, multiply the dynamic load by the partial factor for dynamic load to obtain the design value of the dynamic load. This design value reflects the actual effect of the dynamic load on the guyed tower foundation after considering the uncertainty factors. Perform a weighted summation of the design value of the static load and the design value of the dynamic load (in some cases, other types of loads, such as temperature load, snow load, etc., may also need to be considered and weighted summation accordingly) to obtain the design load. This design load is the total force condition of the guyed tower foundation under the combined action of various loads.

[0149] Step 3: Based on the design load and the ground anchor resistance, obtain the analysis results of the foundation load capacity of the guyed tower.

[0150] Compare the design load with the ground anchor resistance to determine whether the ground anchor can provide sufficient resistance to resist the design load. If the design load is less than or equal to the ground anchor resistance, it is considered that the guyed tower foundation is safe; if the design load is greater than the ground anchor resistance, it is necessary to consider strengthening the foundation design or taking other measures to improve the structural stability. Based on the comparison results and analysis, corresponding improvement suggestions are put forward, such as increasing the number of ground anchors, changing the type or size of the ground anchor, optimizing the foundation design, etc.

[0151] Next, a specific application example will be used to illustrate the entire foundation load capacity analysis process in detail.

[0152] In a specific application example, the foundation needs to bear the combined action of static load and dynamic load, and at the same time, the ground anchor needs to provide sufficient resistance to ensure the stability of the foundation. When designing the foundation, the ultimate limit state design method is usually adopted, considering the combination coefficient and partial coefficient of the load. For example, for the ultimate limit state of bearing capacity, the design load borne by the foundation can be expressed as:

[0153]

[0154] where is the partial coefficient of dead load (static load), is the partial coefficient of live load (dynamic load), and its value can be determined according to the relevant building structure design code. Then the design load is compared with the allowable tensile force of the ground anchor. If , and the bearing capacity of the foundation itself is greater than , then the foundation design is safe and reliable under the action of the load. Otherwise, it is necessary to re-adjust the foundation design parameters (such as increasing the foundation size, increasing the number of piles, improving the ground anchor design, etc.), and re-perform the above calculation process until the design requirements are met.
