Prediction of maximum surface settlement caused by earth pressure balance shield tunneling using random forest
Due to urbanization and population increase, need for metro tunnels, has been considerably increased in urban areas. Estimating the surface settlement caused by tunnel excavation is an important task especially where the tunnels are excavated in urban areas or beneath important structures. Many models have been established for this purpose by extracting the relationship between the settlement a...
متن کاملApplication of artificial intelligence methods for estimation of maximum surface settlement caused by EPB shield tunneling
Maximum surface settlement (MSS) is an important parameter for the design and operation of earth pressure balance (EPB) shields that should determine before operate tunneling. Artificial intelligence (AI) methods are accepted as a technology that offers an alternative way to tackle highly complex problems that can’t be modeled in mathematics. They can learn from examples and they are able...

متن کاملModel Reference Control for Bulkhead Pressure of EPB Shield in Tunneling
The supporting pressure is achieved through control of the incoming and outgoing materials in the head chamber in shield tunneling, i.e., through regulation of the screw conveyor rotation, thrust force of jacks and the excavation advance rate. The discrete state equation of controlling system is derived based on mechanical equilibrium principle. The objective function of model reference control...
متن کاملNumerical modeling of tunneling induced ground deformation and its control
Tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. The predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. The commonly used Earth pressure balance (EPB) tunneling machines, uses the excavated soil in a pressu...
