The implementation of the quality control/detection system of the construction process of long and huge tunnels has great significance to ensure the works quality and operation safety of the tunnels. Construction process quality control/detection system is implemented during the construction of Wulongshan tunnel on Zhensheng highway. In the paper, efforts are made to preliminarily establish the construction process quality control/detection system of long and huge tunnels so as to facilitate the quality management and quality control during construction. The concept of achieving works quality control by implementing the construction process quality control/detection system proposed can be used as reference for the construction of similar long and huge tunnels in the future.
