Description

Technical Field

[0001] The present invention relates to the field of engineering vibration technology, and in particular to a soil dynamic characteristic parameter analysis method and device. Background Art

[0002] With the development of the manufacturing industry, many machinery factories have a large number of power machines. If the vibration control of the power machine foundation is not appropriate, it may cause some harm, which is mainly manifested in the following aspects: (1) Equipment damage: causing wear, cracks and fatigue of machine parts, shortening the service life of the equipment, increasing maintenance costs, etc. (2) Safety hazards: causing equipment parts to loosen or fall off, causing equipment accidents or causing personal injury. (3) Deterioration of working conditions: the vibration and noise generated affect the health and production efficiency of workers. (4) Impact on precision equipment: vibration will interfere with the normal operation of precision equipment and instruments, affecting measurement and production accuracy. (5) Environmental impact: excessive vibration will affect the stability of surrounding buildings and facilities, and even cause problems such as soil subsidence.

[0003] The foundation design plays a very important role in reducing the vibration hazards of power machines. The foundation design of power machines needs to consider the dynamic characteristic parameters of the foundation soil, which are crucial to the stability and vibration absorption capacity of the foundation.

[0004] Some common dynamic characteristic parameters of foundation soil: (1) dynamic elastic modulus of soil; (2) damping ratio of soil; (3) wave velocity of soil; (4) bearing capacity of soil, etc. The natural foundation compressive stiffness coefficient given in the "Design Standard for Power Machinery Foundation" is an important parameter. It reflects the deformation properties of foundation soil under pressure and provides an effective basis for dynamic design.

[0005] The natural foundation compressive stiffness coefficient is usually used to describe the stiffness characteristics of the foundation soil, that is, the deformation resistance of the soil when it is subjected to load. This parameter is very important for the design of the foundation of power machinery, because it can help engineers evaluate the bearing capacity and deformation characteristics of the foundation soil, so as to design a suitable foundation structure to ensure stable operation of the equipment and reduce vibration hazards.

[0006] Since the basic dynamic parameters of natural foundations vary with the nature and structure of the foundation soil, the compressive stiffness coefficient given by the standard cannot be universally applied in practice, and in-situ measurements cannot be carried out on site.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Figure 1 FIG. 1 is a flow chart of a soil dynamic characteristic parameter analysis method according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0031] Step S101, obtaining a general model according to the foundation model, the final deformation relationship and the bearing capacity characteristic value relationship, wherein the general model is , is the foundation reaction coefficient, is the characteristic value of bearing capacity, is the compressive stiffness reference coefficient, is the index correction factor.

[0032] Specifically, according to the foundation model Can be converted into , then Substitution get Taking general clay soil as an example, we can get , and then converted to , and For the same parameter, Substitution get . From this we can get, is the compressive stiffness reference coefficient of the model, It is the exponential correction coefficient of the characteristic value of the bearing capacity of the foundation.

[0033] Step S102, performing regression analysis on the general model to obtain the compressive stiffness reference coefficient and the exponential correction coefficient, and obtaining the final model, wherein the final model is ,in, is the compressive stiffness coefficient, is the soil type correction factor.

[0034] Specifically, the general model is In Replace with , we get a power function Then the power function is linearly changed to obtain the compressive stiffness benchmark coefficient and the exponential correction coefficient, and the soil type correction coefficient is added to obtain the final model .

[0035] Step S103, obtaining the soil compressive stiffness coefficient according to the final model.

[0036] Specifically, the compressive stiffness coefficient can be obtained based on the soil type correction coefficient and the characteristic value of bearing capacity. When analyzing the stiffness coefficient model of foundation soil, the stiffness coefficient of foundation soil can be obtained through the final model. The stiffness coefficient of foundation soil can affect the deformation behavior and bearing capacity of the soil. A mathematical model with physical significance is established to more conveniently solve the problems of foundation soil dynamics in engineering.

[0037] The compressive stiffness coefficient of foundation soil refers to the deformation characteristics of soil under stress, and is usually used to describe the stiffness and deformation characteristics of soil. In soil mechanics and foundation engineering, the stiffness coefficient of foundation soil is an important parameter that can affect the deformation behavior and bearing capacity of soil. When analyzing the stiffness coefficient model of foundation soil, factors such as the material properties, stress state, and water content of the soil are usually considered. Common foundation soil stiffness coefficient models include elastic models, constitutive models, etc.

[0038] Elastic model: The elastic model assumes that the soil exhibits linear elastic behavior within a small strain range, that is, there is a linear relationship between stress and strain. In this model, the stiffness coefficient of the foundation soil can be described by the elastic modulus, which is usually used to represent the stiffness of the soil.

[0039] Constitutive model: The constitutive model takes into account the nonlinear deformation characteristics of soil at different strain levels. Common constitutive models include elastoplastic model, constitutive model, etc. These models can more accurately describe the nonlinear deformation behavior of soil, including elastic and plastic stages.

[0040] In actual engineering analysis, it is usually necessary to select an appropriate foundation soil stiffness coefficient model based on specific site conditions and engineering requirements. Through appropriate model analysis, the deformation and bearing capacity of the soil can be predicted more accurately, providing a reference for engineering design and construction.

[0041] The calculation of foundation settlement is a complex process involving multiple factors and calculation methods. Foundation settlement mainly refers to the sinking of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Its calculation methods include the layered summation method, the elastic mechanics formula method, etc., but the actual calculation is often affected by various conditions such as soil layer properties, load size, time factors, etc., resulting in differences between the calculation results and the actual observed values. In order to calculate the foundation settlement more accurately, it is necessary to comprehensively consider factors such as the compression characteristics of the soil layer, the stress diffusion effect, and the influence of time on settlement. In addition, engineering experience also plays an important role in determining the reasonable amount of foundation settlement.

[0042] When the vibration of the foundation can be regarded as a small deformation problem, the elasticity theory can usually be used for analysis. The elasticity theory is a classic engineering mechanics theory that is suitable for describing the elastic deformation of an object under the action of force. In the small deformation problem of foundation vibration, the foundation and structure can be regarded as elastic bodies with linear elastic properties.

[0043] By applying elastic theory, people can quantitatively analyze the response of foundations under vibration. This includes calculating the vibration frequency, modal form, vibration amplitude and other parameters of the foundation to evaluate the impact of vibration on the structure. At the same time, elastic theory can also be used to design appropriate structures and foundation systems to meet the requirements of vibration response.

[0044] In general, when the vibration of the foundation can be regarded as a small deformation problem, elasticity theory is an effective tool to gain a deeper understanding and analysis of the vibration response of the foundation.

[0046] Specifically, it is assumed that the pressure intensity at any point on the foundation surface is proportional to the settlement of that point, that is, In the formula, the foundation is essentially regarded as a number of independent vertically arranged springs, and the stiffness of the springs is the foundation coefficient , which is also the foundation reaction coefficient.

[0047] In an optional embodiment, the final deformation relationship is obtained, and the calculation formula is: ,in, is the final deformation of the foundation, Calculate the empirical coefficient for settlement, is the number of soil layers divided within the depth range of foundation deformation calculation, is the additional pressure at the bottom of the foundation, The bottom surface of the foundation The compression modulus of the soil layer, , From the base to the layer of soil, No. The distance from the bottom of the soil layer, , Calculate the base bottom surface from point layer of soil, No. The average additional stress coefficient within the bottom surface of the soil layer.

[0048] Specifically, when the soil layer is a uniform single soil layer within the effective range, Can be simplified to: .

[0049] In an optional embodiment, the first soil type parameter and the second soil type parameter are obtained according to the soil type of the foundation; the bearing capacity characteristic value relationship formula is obtained, and the bearing capacity characteristic value relationship formula is ,in, is the characteristic value of bearing capacity, is the compression modulus of soil, is the first soil type parameter, is the second soil type parameter.

[0050] Specifically, the basic allowable value of foundation bearing capacity of general clay soil is [ ] can be calculated according to the following formula. In the formula, is the allowable bearing capacity of general clay soil, that is, the characteristic value of bearing capacity (kPa); Different first soil type parameters and second soil type parameters can be obtained according to different foundation soil types.

[0051] In an optional embodiment, the compressive stiffness coefficient is substituted into the general model to obtain a power function model, and the power function model is logarithmically transformed to obtain a linear relationship, wherein the power function model is: , the linear relationship is The linear relationship is subjected to regression analysis to obtain the compressive stiffness benchmark coefficient and exponential correction coefficient.

[0052] Specifically, for the power function: , can be logarithmically transformed to obtain a linear relationship, The results of regression analysis are: ; The function graph is as follows Figure 2 .

[0053] Before the regression analysis, the three mathematical models were subjected to regression analysis to compare which mathematical model can be used for a smaller relative error. The analysis results are as follows.

[0054]

[0055] The analysis results show that the power function has the smallest error and has physical significance after theoretical analysis and derivation. In summary, and considering the influence of different soil types, the compressive stiffness coefficient of foundation soil can be calculated using the following formula: , where: is the soil type correction factor, clay soil , silt , sandy soil .

[0056] In an optional embodiment, a soil type correction coefficient and a bearing capacity characteristic value are obtained according to the type of soil; the soil type correction coefficient and the bearing capacity characteristic value are substituted into the final model to obtain the soil compressive stiffness coefficient.

[0057] Specifically, we will use The calculation results are compared with the existing natural foundation compressive stiffness coefficient. The results are good and the error is small. The analysis and comparison results are as follows Figure 3 shown.
