متن کاملA Numerical Investigation of TBM Disc Cutter Life Prediction in Hard Rocks
There is a direct relationship between the efficiency of mechanized excavation in hard rocks and that of disc cutters. Disc cutter wear is an important effective factor involved in the functionality of tunnel boring machines. Replacement of disc cutters is a time-consuming and costly activity that can significantly reduce the TBM utilization and advance rate, and has a major effect on the total...
متن کاملPrediction 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 کاملEngineering geological studies used for redesigning and employing a hard rock TBM in soft rock formations of Chamshir water conveyance tunnel
The Chamshir water conveyance tunnel (CWCT) with a length of 7.4 km and boring diameter of 5.3 m is excavated using a refurbished single shield TBM, initially designed to work in hard rock formations. This study focuses on engineering geological issues, which are important for checking the suitability of this machine and proposing required modifications for improving its performance in soft roc...
متن کاملEvaluation of Disc Cutter Performance in Rock Cutting Process Using 3D Finite Element Method
Today, numerical simulation can be used as a suitable tool to measure large quantities that are very expensive and, in some cases, impossible to measure. One of the important issues in predicting rock mass boreability in excavation with full face tunnel boring machines is estimating the discchr('39')s forces for rock cutting. For this purpose, the linear cutting test is employed. However, limi...
