Abstract The complexity and uncertainty of the geological body, the concealment of the structure, and the distur? bance in natural environment caused by tunnelling make the tunnel project built by conventional tunnelling very special compared to common types of construction projects. So, it is still necessary to discuss the safety risk, quality and environmental friendliness of the conventional tunnelling. In respect of the three themes mentioned above, this paper aims to address the following problems: (1) Data interpretation and information feedback in in-situ monitoring process is not yet successful. (2) The integration of the support system is the key issue concerning the tunnelling quality. (3) An innovative concept of tunnel waterproofing needs to be put forth for environmental friendliness.
