Problems solved by technology

Although the above-mentioned method of intelligently controlling tunneling control parameters similar to the intelligent algorithm has high prediction accuracy, it only considers the influence and adjustment of the front geology on the tunneling control parameters, and does not take into account the overall parameters of muck improvement and grouting.
However, in actual excavation, the parameters of muck improvement and grouting have a great influence on shield excavation, which may mislead the construction personnel to adjust the pressure of the soil bin. Therefore, the intelligent control of excavation control parameters recommended by the above method is not optimal. Driving control parameters

Abstract

The invention provides a shield tunneling control system and method. The system comprises a soil bin pressure control value determination unit which is used for calculating a soil bin pressure value of a target stratum, and determining a current tunneling soil bin pressure control value based on the soil bin pressure value, an on-line monitoring unit and a control unit. The on-line monitoring unit is used for monitoring a characteristic information value of the target stratum in real time, and the characteristic information value is monitored when a shield manipulator conducts tunneling operation according to current tunneling control parameters under the condition that the soil bin pressure control value is kept; the control unit is used for obtaining an adjustment value of a tunneling control parameter according to the characteristic information value; and according to the adjustment value of the tunneling control parameter, a current tunneling control parameter is adjusted until characteristic information reaches a stable state. According to the system, control of shield tunneling can be realized, and the control precision is high.

Description

technical field [0001] The invention relates to the technical field of shield machine construction automation and intelligence, in particular to a shield tunneling control system and method. Background technique [0002] The shield machine is a special engineering equipment for tunnel excavation, which can realize tunnel construction operations such as excavating rock and soil, belt slag removal, synchronous grouting, and segment assembly. At present, in most shield tunneling constructions, the pressure control value of the soil bin is calculated by a theoretical formula, and adjusted according to the later ground subsidence value, and the project management personnel issue instructions, which has a certain lag; due to the geological conditions in front of the shield tunnel Complex and changeable, the tunneling control parameters change quickly, and the main driver adjusts according to the changes of the tunneling control parameters relying on personal experience; but in fac...
