Therefore, it is urgent to carry out research on the longitudinal uneven settlement performance of red clay sites comprehensive pipe gallery.

[0003] However, the analysis result of the influence of longitudinal uneven settlement of the red clay comprehensive pipe gallery in the related art is not accurate, which causes the subsequent optimization design of the red clay comprehensive pipe gallery based on the analysis result to be unable to obtain a better red clay comprehensive pipe gallery.

[0026] The application provides a method, device, equipment, medium and product for analyzing the influence of longitudinal uneven settlement of a red clay comprehensive pipe gallery, and the existing research on the settlement analysis of the comprehensive pipe gallery is mostly based on the assumption of homogeneous soil, without fully considering the additional settlement effect caused by the sudden change of soil stiffness in the longitudinal direction and the tunnel construction. Moreover, the prefabricated comprehensive pipe gallery is mostly built under the road with dense traffic in the city, and the traditional method usually adopts a static load model, ignoring the dynamic coupling effect of the vehicle dynamic load and the red clay-comprehensive pipe gallery structure system, resulting in a large deviation between the evaluation results and the actual working conditions. In addition, in the areas where red clay is widely distributed and the soil layer is mostly uneven, there are relatively few research literatures on the longitudinal uneven settlement of the red clay-comprehensive pipe gallery structure system, and therefore, the research on the response characteristics, failure mechanism and failure mode of the longitudinal uneven settlement of the red clay-comprehensive pipe gallery structure system is not comprehensive, and the influence of the uneven underlying soil layer has not been considered.

[0027] Currently, in order to alleviate the pressure of gradually saturated utilization rate of urban surface space, more and more regions turn to develop underground space and establish underground engineering such as tunnels. When the tunnel is excavated and constructed, it will disturb the surrounding soil and make it deform, such as shear, twist and relaxation, and the changed stress field and displacement field of the soil will directly act on the pipe gallery, causing the deformation of the pipe gallery. Among them, the most obvious deformation is the longitudinal uneven settlement of the pipe gallery, which further causes the cracking of the pipe gallery structure and various municipal pipelines inside the pipe gallery, affecting the daily work and life of the city. Therefore, the prefabricated comprehensive pipe gallery in the red clay site has a great influence on the longitudinal uneven settlement of the pipe gallery caused by the tunnel underpass. In view of the problems existing in the performance research on the longitudinal uneven settlement of the above-mentioned red clay site comprehensive pipe gallery, the application first establishes a three-dimensional finite element analysis model of the red clay-comprehensive pipe gallery structure system, and based on multiple working conditions, the influence of the uneven overlying load of the red clay site, the uneven underlying soil layer and the tunnel underpass under the pipe gallery is considered. Compared with the prior art, the application can obtain more accurate analysis results of the influence of the longitudinal uneven settlement of the red clay comprehensive pipe gallery by considering multiple factors, thereby providing a theoretical basis and technical support for the design optimization and longitudinal uneven settlement risk prevention and control of the red clay-prefabricated comprehensive pipe gallery structure system.

[0042] Step 207: Based on the displacement nephogram of the longitudinal cross section of the red clay comprehensive pipe gallery under the uneven underlying soil layer working condition and the displacement nephogram and the structural internal force nephogram of the longitudinal cross section of the red clay comprehensive pipe gallery under the conventional working condition, the tunnel underpass working condition and the uneven underlying soil layer and the tunnel underpass coupling working condition, the influence degree of the uneven underlying soil layer on the longitudinal uneven settlement of the red clay comprehensive pipe gallery, the influence degree of the tunnel underpass under the pipe gallery on the longitudinal uneven settlement of the red clay comprehensive pipe gallery, the influence degree of the coupling effect of the uneven underlying soil layer and the tunnel underpass under the pipe gallery on the longitudinal uneven settlement of the red clay comprehensive pipe gallery and the influence degree of the uneven underlying soil layer and the tunnel underpass under the pipe gallery on the red clay comprehensive pipe gallery are obtained.

[0043] In another exemplary embodiment of the present application, before step 201, it further includes:

[0044] Step 1: The target red clay site is subjected to detailed geological reconnaissance, and the target red clay site conditions are obtained according to the actual engineering geological survey report: the uneven overburden load value and the uneven underlying soil layer distribution; the uneven overburden load value includes the uniform load value and the ground dynamic (live) load value, the uniform load value mainly considers the self-weight load value of the pipe gallery, the vertical soil pressure value of the surrounding soil and the static water pressure value of the underground water, and the ground dynamic (live) load value mainly considers the vehicle load value.

[0047] In another exemplary embodiment of the present application, step 202 specifically includes:

[0048] Considering the longitudinal uneven soil stiffness, the uneven soil stiffness boundary is obtained according to the uneven underlying soil layer distribution.

[0049] In another example embodiment of the present application, the construction process of the three-dimensional finite element analysis model of the red clay comprehensive pipe gallery is as follows:

[0050] Abaqus software is used to establish the three-dimensional finite element analysis model of the red clay comprehensive pipe gallery, and the following assumptions are made for the soil around the pipe gallery: (1) the same soil layer is homogeneous and isotropic, and the red clay site adopts the Mohr-Coulomb yield criterion constitutive model; (2) the pipe piece of the pipe gallery is equivalent to a homogeneous continuous rectangular cabin, and the concrete plastic damage constitutive model is adopted; (3) the initial stress field of the soil only considers its self-weight stress, and the influence of tectonic stress is ignored; (4) adjacent pipe pieces are connected by socket joints, and it is assumed that the lining and soil do not separate during simulation, that is, they always deform in coordination; (5) full binding contact and friction contact are used between the red clay site and the comprehensive pipe gallery structure. Based on the above, the self-weight stress balance of the red clay-comprehensive pipe gallery structure (i.e. the red clay comprehensive pipe gallery), the artificial boundary setting and the equivalent load application on the top surface of the soil are carried out.

[0051] In practical applications, simulation is carried out in Abaqus software.

[0052] In practical applications, the displacement nephogram and the structural internal force nephogram of the longitudinal cross section of the red clay comprehensive pipe gallery are the displacement and structural internal force (structural internal force is axial force, shear force or bending moment) of each point along the longitudinal direction of the longitudinal cross section of the red clay comprehensive pipe gallery.

[0053] In another example embodiment of the present application, step 204 specifically includes:

[0054] According to the uneven soil stiffness boundary, the soil material properties in the three-dimensional finite element analysis model of the red clay comprehensive pipe gallery are set, and the set three-dimensional finite element analysis model is obtained. The specific numerical value of the soil material properties can be selected from the empirical value of the target red clay site soil layer.

[0055] According to the equivalent uniform load value, the set three-dimensional finite element analysis model is simulated to obtain the displacement nephogram of the longitudinal cross section of the red clay comprehensive pipe gallery under the uneven underlying soil layer condition. Specifically, the uneven soil stiffness boundary is corresponded with the longitudinal joint position of the fabricated pipe gallery to study the damage characteristics of the pipe gallery under the most unfavorable condition.

[0056] Based on the theory that the longitudinal settlement of the comprehensive pipe gallery caused by the shield tunnel construction conforms to the Peck curve, in the actual application, the Gaussian settlement curve is used to simulate the longitudinal uneven settlement of the comprehensive pipe gallery when the tunnel under the pipe gallery passes underneath. max 300mm is taken.

[0089] Based on the first difference value displacement nephogram and the second difference value displacement nephogram, the influence degree of the uneven underlying soil layer and the tunnel underpassing under the pipe gallery on each position of the red clay comprehensive pipe gallery bottom plate is obtained; if the first difference value is greater than the second difference value, the influence degree of the uneven underlying soil layer on the red clay comprehensive pipe gallery under the coupling effect is smaller, and vice versa.

[0090] The present application firstly establishes a three-dimensional finite element analysis model of the red clay comprehensive pipe gallery combined with geological reconnaissance data, integrates the uneven overburden load through equivalent uniform load, sets the extreme working condition of aligning the longitudinal soil stiffness boundary with the pipe gallery joint, and simulates the longitudinal uneven settlement of the comprehensive pipe gallery under the tunnel based on the Peck theory using the Gaussian settlement curve. The structural response under different working conditions is calculated, the influence of soil unevenness on the red clay-comprehensive pipe gallery structure system is revealed by comparing the displacement difference of the top and bottom plates considering and not considering the uneven underlying layer, and quantitative discrimination is made combined with the difference in settlement rate. By comparing the extreme value difference of longitudinal displacement and internal force between the tunnel underpass working condition and the conventional no tunnel underpass working condition, the response characteristics are analyzed to determine the dangerous section of the pipe gallery. By comparing the influence of the red clay-comprehensive pipe gallery structure system considering the coupling effect of uneven settlement of the underlying soil layer and tunnel underpass, the influence degree of the two on the red clay-comprehensive pipe gallery structure system is further distinguished. The method will provide theoretical basis and technical support for the design optimization and longitudinal uneven settlement risk prevention and control of the red clay-assembled comprehensive pipe gallery structure system, and has an important role in promoting the continuous popularization and construction of urban comprehensive pipe gallery.

[0091] The present application comprehensively considers the complex geological conditions of red clay site, tunnel underpass effect and assembled structure characteristics, quantifies the damage mechanism of uneven settlement on the pipe gallery, and provides a theoretical basis for the optimization design of red clay comprehensive pipe gallery.

[0092] The present application establishes a three-dimensional finite element model of the red clay-comprehensive pipe gallery structure system, simulates the influence of uneven underlying soil on the red clay-comprehensive pipe gallery structure by setting the longitudinal soil stiffness unevenness of red clay soil layer. By comparing the displacement difference of the top and bottom plates considering and not considering the uneven underlying layer, the influence of soil unevenness is quantitatively analyzed combined with the settlement rate, which solves the problem that the traditional method cannot quantize the influence of soil stiffness mutation on the longitudinal deformation of the pipe gallery. The model uses Mohr-Coulomb constitutive to describe the characteristics of red clay, and simulates the coordinated deformation of soil and pipe gallery through full binding contact, so that the analysis result is closer to the actual engineering scene. The influence of red clay site unevenness on the assembled comprehensive pipe gallery can be accurately simulated.

[0093] The application researches the structural damage characteristics in the most unfavorable condition by aligning the soil stiffness boundary with the pipe gallery joint, fills the analysis blank of the current design for the coupling effect of "soil stiffness mutation + joint weak link". The traditional design usually ignores the synergistic effect of longitudinal joint and soil unevenness, but the application can reveal the stress concentration phenomenon at the joint position through refined modeling (such as socket interface simulation, high-precision artificial boundary setting), and provide data support for pipe gallery node structure optimization. By setting the extreme working condition of aligning the longitudinal soil stiffness boundary with the joint position, combined with the deformation coordination assumption of socket interface, the most unfavorable damage mode of the fabricated pipe gallery under complex geological conditions is effectively simulated. The application first couples the uneven distribution of soil stiffness with the mechanical behavior of pipe gallery joint, significantly improving the evaluation accuracy of the longitudinal settlement sensitivity of fabricated structure. By setting the extreme working condition of aligning the longitudinal soil stiffness boundary with the joint position, combined with the deformation coordination assumption of socket interface, the most unfavorable damage mode of the fabricated pipe gallery under complex geological conditions is effectively simulated.

[0094] Based on the Peck theory, the application simulates the longitudinal uneven settlement caused by tunnel underpassing by using Gaussian settlement curve. By comparing the difference in longitudinal displacement and internal force extreme value under the condition of considering and not considering tunnel underpassing, the dangerous section of the pipe gallery can be accurately identified. For example, by calculating the difference between the axial force, shear force and bending moment, the additional stress distribution caused by tunnel underpassing can be determined, avoiding the limitations of traditional empirical method for response analysis of complex working conditions. The application integrates the overburden load by equivalent uniform load and introduces the dynamic load coefficient, so that the load model is more consistent with the actual stress state. The response characteristics of the pipe gallery under the tunnel underpassing condition can be quantified.
