| Abstract | Earth Pressure Balanced (EPB) Shield Tunneling is known for its effectiveness in minimizing ground movements. However, the relationship between each influencing factor on the ground movement is not well understood due to a large number of the factors. Based on the observed data from the first Bangkok MRTA project, an application of an optimal neural network model for study of the behavior of influencing parameters including tunnel geometry, stability number, geological condition, and shield operation factors are studied. This study is conducted to determine which factor has the greatest effect on surface settlement induced by EPB shield tunneling. By implementing monitored data from Suwansawat (2002) and MRTA Thailand with MATLAB Neural Network Toolbox, the results indicated that the neural network can be used to predict maximum surface settlement and to model the relationship between surface settlement and the influencing factors even only small amount of collected field data are provided. However, parametric studies through the optimal model shown that only face pressure and grouting pressure play the key roles in controlling surface settlement induced by EPB shield tunneling solution to the trends suggested by the monitoring data. |
