This method obtains the soil and rock characteristics of the target area of the tunnel to be excavated, determines geological stratification prediction information based on the soil and rock characteristics, determines preset process parameters for the excavation process based on the geological stratification prediction information, and controls the working state of the excavation equipment based on the preset process parameters.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.
[0019] Please see Figure 1 This is a schematic flowchart of a tunnel hard-soft interlayer excavation control method provided in an embodiment of this application, which may specifically include: S110. Obtain the soil and rock characteristics information of the target area corresponding to the tunnel to be excavated; For example, soil and rock properties can be obtained by conducting geological exploration of the target area and processing the data from the geological exploration. Soil and rock property information includes the material of the soil and rock, its hardness, shear strength, elastic modulus, etc.
[0020] S120. Based on the above-mentioned rock and soil characteristics information, determine the geological stratification prediction information of the above-mentioned target area, wherein the above-mentioned geological stratification prediction information includes the physical properties of geological materials and the geological layer thickness ratio. For example, the geological stratification prediction information of the target area is determined based on the rock and soil characteristic information. That is, based on the physical properties of geological materials in the rock and soil characteristic information, such as hardness, shear strength and elastic modulus, the soft layer and hard layer are determined according to the variation law of physical properties, and the geological layer thickness ratio between the soft layer and the hard layer is determined.
[0021] S130. Based on the above geological stratification prediction information, determine the preset process parameters for the tunnel to be excavated during the excavation process, wherein the preset process parameters include preset excavation force and preset excavation speed. For example, based on geological stratification prediction information, preset process parameters for different geological layers can be determined. These parameters include preset tunneling force and preset tunneling speed. It is understood that the tunneling force is lower in soft layers compared to hard layers, while the preset tunneling speed can be appropriately increased. Specific tunneling force and speed values can be determined based on historical construction process parameters.
[0022] S140. Control the working state of the tunneling equipment based on the above-mentioned preset process parameters, wherein the above-mentioned working state includes tunneling force and tunneling speed.
[0023] For example, the working state of the tunneling equipment can be controlled according to preset process parameters, that is, the tunneling force and tunneling speed of the tunneling equipment can be controlled by preset tunneling force and preset tunneling speed, so as to control the working state of the tunneling equipment to correspond to the distribution characteristics of soft and hard interlayers, thereby improving the safety in the construction process of soft and hard interlayer tunnels.
[0024] In summary, the tunnel excavation control method for alternating soft and hard layers provided in the application embodiments obtains the soil and rock characteristics of the target area of the tunnel to be excavated, determines the geological stratification prediction information based on the soil and rock characteristics, determines the preset process parameters in the excavation process based on the geological stratification prediction information, and controls the working state of the excavation equipment according to the preset process parameters, so that the working state of the excavation equipment corresponds to the distribution characteristics of the alternating soft and hard layers, thereby improving the safety in the construction process of tunnels with alternating soft and hard layers.
[0025] In some examples, the above method also includes: To obtain information on the changes in tunneling stress during the tunneling process; Based on the above information on tunneling stress changes and the above preset process parameters, the first process adjustment parameters are determined. Adjust the working status of the tunneling equipment according to the first process adjustment parameters mentioned above.
[0026] For example, during the tunneling process, the stress change information at the target tunnel excavation end fed back by the tunneling equipment is monitored. This stress change information is compared with preset process parameters to determine the first process adjustment parameters, and the operating state of the tunneling equipment is adjusted accordingly. Due to the limitations of geological exploration accuracy, the estimated geological stratification information determined by exploration may differ from the actual stratification information. Therefore, by continuously acquiring information on stress changes during tunneling and adjusting the operating state of the tunneling equipment in real time, the construction safety of tunnels with alternating layers of soft and hard strata can be improved.
[0027] In some examples, the determination of the first process adjustment parameter based on the aforementioned tunneling stress variation information and the aforementioned preset process parameters includes: If the aforementioned tunneling stress change information exceeds the preset first stress change threshold, the first process adjustment parameter is determined based on the aforementioned tunneling stress change information and the aforementioned preset process parameters.
[0028] For example, when the tunneling stress change information exceeds a preset first stress change threshold, a first process adjustment parameter is determined based on the tunneling stress change information and preset process parameters. This parameter is then used to adjust the process parameters of the tunneling equipment to meet the detailed structural characteristics of the excavated tunnel cross-section. Adjustments to the preset process parameters are only made when the stress change information exceeds the first stress change threshold, avoiding frequent changes in process parameters due to minor differences. In other words, process parameter adjustments are only made when switching between soft and hard layers.
[0029] In some examples, the above method also includes: A three-dimensional model of the tunnel was constructed based on the above geological stratification prediction information. The measured stress information of the excavation section is used as the input information for the above-mentioned three-dimensional tunnel model to obtain the simulation stress information; If the difference between the simulated stress information and the measured stress information during the tunneling process exceeds the second stress change threshold, the second process adjustment parameter is determined based on the difference between the simulated stress information and the measured stress information and the preset process parameters, wherein the second stress change threshold is greater than the first stress change threshold. Adjust the working status of the tunneling equipment according to the second process adjustment parameters mentioned above.
[0030] For example, a 3D model of the tunnel is constructed using 3D simulation software based on geological stratification prediction information. Mechanical sensors are pre-embedded in the excavated sections to acquire measured stress information. This measured stress information is then used as input to the 3D model for numerical simulation to obtain simulated stress information. This simulated stress information includes stress information at the currently excavated section and measured stress information acquired by the tunneling equipment. If the measured stress information and the simulated stress information exceed a second stress change threshold, the simulation result is considered to differ significantly from the measured result. This phenomenon may be due to the simulation result being based on geological stratification prediction information, which may differ from the actual geological structure. Therefore, controlling the working state of the tunneling equipment through preset process parameters cannot meet the requirements of the actual geological conditions. A second process adjustment parameter is determined based on the difference between the true stress information and the measured stress information, along with the aforementioned preset process parameters, thereby adjusting the process state of the tunneling equipment.
[0031] In some examples, the above method also includes: If the time interval between the adjustment times corresponding to the first process adjustment parameter and the second process adjustment parameter is less than the first preset duration, the previous process adjustment parameter is adjusted a second time based on the average value of the first process adjustment parameter and the second process adjustment parameter.
[0032] For example, the first process adjustment parameter is obtained based on the measured stress change over a short period of time, and the second process adjustment parameter is obtained based on the difference between the simulated stress information and the measured stress information. If the first process adjustment parameter and the second process adjustment parameter are activated simultaneously within a short period of time, i.e. less than the first preset time, it is determined that the process parameter adjustment is based on the same soft and hard layer change. In this case, the previous process adjustment parameter is modified based on the average value of the two process adjustment parameters.
[0033] In some examples, the above method also includes: If the adjustment time interval between the first process adjustment parameter and the second process adjustment parameter is greater than the first preset time and less than the second preset time, the previous process adjustment parameter is adjusted a second time based on the difference between the first process adjustment parameter and the second process adjustment parameter and the time interval.
[0034] For example, if the adjustment time interval between the first process adjustment parameter and the second process adjustment parameter is greater than the first preset time and less than the second preset time, it is considered that there is a continuous change in hardness between the soft and hard layers within a certain tunneling length. In this case, the previous process adjustment parameter is adjusted based on the difference between the two process parameters and the time interval. For instance, if the time interval is closer to the first preset time, the first process adjustment parameter is used to adjust the working state of the tunneling equipment; if the time interval is closer to the second preset time, the second process adjustment parameter is used to adjust the working state of the tunneling equipment.
[0035] In some examples, the above-mentioned secondary adjustment of the previous process adjustment parameters based on the difference between the first process adjustment parameters and the second process adjustment parameters and the time interval includes: The weighting coefficients are determined based on the aforementioned time intervals; Based on the aforementioned weighting coefficients and differences, the previous process adjustment parameters are adjusted a second time.
[0036] For example, the weighting coefficient is determined based on the time interval. For instance, if the first preset duration is 60 seconds, the second preset duration is 90 seconds, and the time interval is 80 seconds, then the weighting coefficient can be determined as (80-60) / (90-60) = 0.67. The first process adjustment parameter corresponds to a tunneling speed of +2 and a tunneling force of +3, while the second process adjustment parameter corresponds to a tunneling speed of +5 and a tunneling force of +2. The difference in tunneling speed is +3, and the difference in tunneling force is -1. After the second adjustment, the tunneling speed of the process adjustment parameters is +2 + (+3 × 0.67) = +4, and the tunneling force is +3 + (-1 × 0.67) = 2.33. The tunnel hard-soft interlayer tunneling control method provided in this application addresses the situation where the hardness of the hard and soft layers continuously changes within a certain tunneling length. It determines the weighting coefficient based on the time interval and adjusts the previous process adjustment parameters according to the weighting coefficient, thereby adapting to the actual geological conditions of the geological layer.
[0037] Please see Figure 2 One embodiment of the tunnel soft-hard interlayer excavation control device in this application may include: The acquisition unit allows users to obtain geotechnical feature information of the target area corresponding to the tunnel to be excavated; The first determining unit is used to determine the geological stratification prediction information of the target area based on the above-mentioned rock and soil characteristic information, wherein the geological stratification prediction information includes the physical properties of geological materials and the geological layer thickness ratio. The second determining unit is used to determine the preset process parameters of the tunnel to be excavated during the excavation process based on the above-mentioned geological stratification prediction information, wherein the preset process parameters include preset excavation force and preset excavation speed. The control unit is used to control the working state of the tunneling equipment based on the aforementioned preset process parameters, wherein the aforementioned working state includes tunneling force and tunneling speed.
