Study on Thrust of Earth-Pressure-Balanced Shield Tunneling in Gravel
High chamber earth pressure will lead many difficulties when shield driving in gravel layer. To overcome these shortcomings and enhance the efficiency, the contractor usually wishes to decrease the chamber pressure. To examine the basis of the make up of driving resistance, a three dimensional numerical model is built and the resistance distribution around shield is revealed. By analysis of field test data, the relationship of cylinder thrust, chamber earth pressure and driving efficiency is obtained. The results show that decreasing the chamber pressure to a certain extent can achieve a high driving efficiency.
