Abstract
According to actual engineering of a highway neighborhood tunnel, The surrounding rock stress field monitoring of bench cut method has done and the field monitoring data has been compared with numerical simulation results. The result shows: The surrounding rock stress release with time in excavation, every construction step can effect the stress of surrounding rock and lining. The construction of excavation and the secondary can disturb the surrounding rock stress near another tunnel in neighborhood tunnel. After the completion of secondary lining, the stress of primary lining have decreased and secondary lining receives apart of surrounding pressure.
