Discussion ground setting in the shield construction;

Numerical analysis of the instability of excavation face in shield construction;

A comparison and analysis of various types of grou- ting behind segment in shield construction;

Numerical analysis of the varying law of tunnel surrounding soil displacement produced by shield tunneling;

Preliminary study of typical fault diagnosis in shield tunneling

Shield tunneling is characterized by quicker speed and higher quality,affecting slightly on the environ- ment and with higher construction security.

Application of Static Cone Penetration to Studying the Disturbance of Soil Induced by Shield Tunnelling;

The mechanism of disturbance caused due to shield tunnelling is analysed and verified by using the specific penetration resistance and the pore pressure gained from site test on soft clays, which is a feasible and effective way to study the disturbance of soil mass during tunnel construction.
