[0038] Please refer to Figure 1 , which is a schematic flow chart of a method for determining the construction temperature of a tunnel in cold regions provided by an embodiment of the present application, and specifically may include:
[0039] S110. Obtain the working parameters of the tunneling equipment, where the above-mentioned working parameters include working stress and working speed;
[0040] Exemplarily, the tunneling equipment may be equipment such as a shield machine or a tunneling machine. When the tunneling equipment is tunneling, it tunnels through the rotation of the components installed at the head. During the rotation process, it will rub against the unmined tunnel rock and soil, generating heat, which affects the temperature of the rock and soil on the surface being processed. At the same time, different working stresses and working speeds will result in different friction and impact effects on the tunnel rock and soil, thus forming different frictional heats, which in turn affect the construction temperature of the surface being processed.
[0041] S120. Obtain the tunneling temperature parameters based on the temperature sensor of the above-mentioned tunneling equipment;
[0042] Exemplarily, the tunneling temperature parameter is obtained according to the temperature sensor of the tunneling equipment, that is, the temperature of the tunneling equipment is obtained through the temperature sensor of the tunneling equipment. However, since the compositions and densities of the tunneling equipment and the rock and soil are different, the tunneling temperature parameter is not the same as the temperature of the rock and soil.
[0043] S130. Obtain the static temperature parameter according to the temperature sensor on the mined wall surface;
[0044] Exemplarily, during normal construction, in addition to paying attention to the temperature of the surface being processed, it is also necessary to pay attention to the temperature of the mined wall surface. During the construction process, temperature sensors will be prefabricated on the mined wall surface to obtain the static temperature parameter of the mined wall surface.
[0045] S140. Determine the construction temperature according to the above working parameters, the above tunneling temperature parameter, and the above static temperature parameter.
[0046] Exemplarily, through the working parameters of the tunneling equipment, the tunneling temperature parameter obtained by the temperature sensor of the tunneling equipment, and the static temperature parameter obtained by the temperature sensor of the mined wall surface, the construction temperature of the wall surface being mined can be calculated through the heat transfer law or by performing thermal simulation, so as to accurately determine whether there are phenomena such as frozen soil melting during the driving process, and further guide the tunneling work.
[0047] In summary, the method for determining the construction temperature of a cold-region tunnel proposed in the embodiment of the present application obtains the working parameters, tunneling temperature parameter, and tunneling temperature parameter of the mined wall surface of the tunneling equipment, and combines the heat transfer law or performs thermal simulation to calculate the construction temperature of the wall surface being mined, so as to accurately determine whether there are phenomena such as frozen soil melting during the driving process, and further guide the tunneling work.

[0051] Exemplarily, the working stress of the tunneling equipment includes axial working stress, and the tunneling temperature parameter can include axial tunneling temperature parameter. The axial construction temperature, the temperature of the construction vertical surface, can be obtained through heat transfer calculation or simulation calculation according to the axial working stress, the working speed of the tunneling equipment, the axial tunneling temperature, and the static temperature parameter.
[0052] In some examples, the above working stress includes circumferential working stress, the above tunneling temperature parameter includes circumferential tunneling temperature parameter, and the above construction temperature includes circumferential construction temperature;

[0055] Exemplarily, the working stress of the tunneling equipment further includes circumferential working stress, and the tunneling temperature parameter can further include circumferential tunneling temperature parameter. The circumferential construction temperature, i.e., the temperature of the circumferential wall surface under construction, can be obtained through heat transfer calculation or simulation calculation based on the circumferential working stress, the working rotational speed of the tunneling equipment, the circumferential tunneling temperature and the static temperature parameter.
[0056] In some examples, the above method further includes:
[0057] Obtaining the thermal conductivity of the rock and soil;
[0058] Constructing a construction surface temperature field based on the above thermal conductivity, the above axial construction temperature and the above circumferential construction temperature.
[0059] Exemplarily, for the temperature of the rock and soil calculated at the corresponding position of the temperature sensor obtained in the foregoing embodiments, in this embodiment, by obtaining the thermal conductivity of the rock and soil, the temperature field of the entire construction surface can be constructed according to the thermal conductivity and the temperature of the construction surface obtained by the above method, and is displayed through the corresponding cloud map, so that engineers can clearly observe the temperature distribution of the surface under processing, and thus can easily formulate a mining plan.
[0060] In some examples, the above obtaining the construction temperature according to the above working parameters, the above tunneling temperature parameters and the above static temperature parameters includes:
[0061] Obtaining the construction temperature according to the above working parameters, the above tunneling temperature parameters, the above static temperature parameters and the simulation result, wherein the above simulation result is obtained by performing temperature field simulation in a preset geological model according to the preset friction force, the preset shear force, the preset tunneling temperature parameter and the preset static temperature parameter.
[0062] Exemplarily, by using simulation software such as ANSYS and CAE, a finite element model is constructed according to the geological characteristics of the construction site, and through dynamic simulation, preset friction force, shear force, preset tunneling temperature parameters, and preset static temperature parameters are input into the simulation model for temperature field analysis after stress application, so as to obtain the simulation results. During the actual tunneling process, the construction temperature of the tunnel wall surface in the current construction process is obtained by matching the working parameters, tunneling temperature parameters, and static temperature parameters with the simulation results.
[0063] In some examples, the above method further includes:
[0064] Obtaining the friction force and shear force during the construction process based on the above working stress and the above working rotational speed.
[0065] Exemplarily, mechanical analysis and decomposition are performed based on the working stress and working rotational speed obtained by the tunneling equipment to obtain the friction force and shear force related to the wall friction, which are then used in the matching process with the simulation results.
[0066] In some examples, the above tunneling temperature parameters are obtained by sensors axially and circumferentially arranged on the above tunneling equipment, and the above static temperature parameters are obtained by temperature sensors reserved in the already mined wall surface.
[0067] Exemplarily, the tunneling temperature parameters can be obtained by temperature sensors arranged axially and circumferentially on the tunneling equipment. During the arrangement of the temperature sensors, since the tunneling equipment operates in a rotating manner, in order to obtain the temperature at more positions, the temperature sensors should be arranged in different rotating planes. The static temperature parameters are obtained by temperature sensors reserved in the already mined wall surface.
