At present, domestic and foreign markets shield works very active, very broad prospects, but also created a more mature theoretical calculation of the structural design and engineering practice system, but the subway shield tunnel construction quality are still some deficiencies have not been well addressed, such as Segment of the water leakage, cracks, Taiwans wrong, Kok Beng, such as the reverse. How to do a good job on the shield tunnel segment of the quality control, will be the impact on the final shape of the key to the quality of shield tunnel. Through a number of shield tunnel segment of quality so as to arrive at the relevant segment of quality control measures to ensure that the final shape the quality of the shield tunnel.
