| Abstract: | Shield technique is seldom used for metro tunneling in sandy cobble ground. In light of the real project practice, a brief introduction is given to the key points of design and construction, EPB shields technique, section internal force computation on the segment lining structure of shield-bored tunnels, cutting of shield machines and thrust technique of pressure due. |
