“…The main part of the engineering risk control is to make sure that the disc cutter can cut reinforced concrete materials by its cutterhead configuration. At the same time, that which can be avoided by adjusting the driving parameters are the problems of low efficiency caused by great slow cutting or high cutter load, as well as excessive wear caused by rapid cutting [27][28][29][30].…”

On the background of a subway project in Suzhou City of Jiangsu Province and targeting the engineering difficulty of disc cutters cutting reinforced concrete walls, this paper illustrates the adaptability of a reinforced concrete diaphragm wall cut by disc cutter through conducting related laboratory tests and numerical simulations. When cutting a reinforced concrete diaphragm wall, the cutter should use the low-penetration depth excavation pattern with the depth of the penetration kept within 10 mm/r. In order to keep the torque in a small floating range, the cutterhead driving speed and thrust should be strictly controlled during the cutting period. Three types of fracture surface after the cutting operation, namely, single-side rolling destroy, double-sided rolling destroy, and brittle destroy. The percentage of the length of the cut steel bar smaller than 60 cm can reach 44.2% when the driving parameters of the disc cutter are well regulated. The simulation results show that the deeper the penetration, the more unstable the cutting load. The relationship between the normal force of the disc cutter and the penetration depth was linear, and the trend of the simulated value was comparable with the experimental one, which ensures the rationality of this pattern. The cutter spacing had little impact on the cutting results when it was wider than 80 mm.

“…The calculation equation was verified with a correlation coefficient of 0.78 and a mean absolute percentage error of 10.9%. Liu et al [22] studied the most important parameters of the rock mass and machine, and increased the average penetration rate of the TBM by 11.10% and the average cutter life by 15.62% by introducing an intelligent decision method for the main control parameters of the TBM based on the multiobjective optimization of excavation efficiency and cost.…”

The thrust system of a tunnel boring machine plays a crucial role by driving the machine ahead and supporting the gripper shoes stably. A thrust hydraulic control system, assembled with a proportional flow control valve and a pressure relief valve, is established with system operating parameters. The mathematical model of a thrust electrohydraulic system is presented. To improve the control characteristics of the thrust system, a self-tuning fuzzy PID controller was introduced in synchronization motion control situations. To attain the best control parameters, three synchronization motion control systems were used to control the thrust propel cylinders. Tests on a Ø2.5 m scaled TBM test rig were carried out to verify the capabilities of the ISCS, SRSCS and CRSCS. Comparative tests were conducted, and the results showed that the thrust system adopting SRSCS achieved the least oscillation and the quickest response. The steady-state displacement error decreased by about 33.3% in contrast to the ISCS and CRSCS.

“…Armaghani et al [24] developed several optimization techniques for predicting the advanced rate of tunnel boring machines (TBMs) in different weathered zones of granite. Liu et al [25] proposed an intelligent decision method for the main control parameters of tunnel boring machines based on multiobjective optimization of excavation efficiency and cost. Aiming at the problem that it is difficult to accurately predict and correct the axis attitude deviation in the shield tunnelling process, Wang et al [26] put forward a prediction of axis attitude deviation and a deviation correction method based on data driven during shield tunnelling.…”

Shield tunnelling has become the development direction of tunnel construction due to its safety, economy, and speed. The complex formation has complicated geological changes, including soft rock, hard rock, and soft and hard inhomogeneous formation. It is particularly difficult to select and control the tunnelling parameters in shield tunnelling, while the reasonable selection and control of the tunnelling parameters play an important role in the excavation efficiency, tool wear, and surface settlement. Based on the tunnel project between the Dinggong Road North Station and the People’s Park Station online 4 of Nanchang Metro during shield tunnelling construction, this paper collects thrust, torque, and revolution speed of the cutterhead during shield tunnelling in the complex strata with differentiated argillaceous siltstone and gravel and analyzes these parameters by means of mathematical statistics analysis, in order to explore the interrelationship between shield tunnelling parameters under different stratigraphic conditions and put forward optimization suggestions for tunnelling parameters, which can provide a reference for control of tunnelling parameters of earth pressure shield in composite strata.
