Abstract Research purposes: According to the situation of some of shield tunnels with internal secondary lining in China，in order to prove the interaction mechanism between the secondary lining and segment lining，the corresponding analysis model was offered for the purposes of evaluating the function of the secondary lining correctly and providing the reference to the proper application of the secondary lining．

Research conclusions: The analysis model of sheafing and compressing resistance for double—layer lining was used to analyze the characteristics of the internal force properties of the structure under three representative kinds of conditions．The result proved that adding secondary lining might increase the moment and decrease the axial force of segment lining，and this effect Was especially obvious when water leakage occurred in the segment lining．Compared with segment lining，the secondary lining only plays an assistant role in the load bearing．With adding the secondary lining，the entire load—bearing of the double—layered lining Was not more reasonable．The ideal combined beating effect of double—layered liner only happened under conditions of specific load，ground parameters and structure parameters．The secondary lining could mainly bear the load when the segment lining completely failed and it played an assistant t role in load bearing．

Key words： shield tunnel double—layered lining segment lining secondary lining interaction model
