First, the content of the intelligent engineering that using the new generation of the information technology, artificial intelligent technology, and robot technology to construct a new tunnel construction mode integrating multiple systems such as intelligent advance geological prediction, intelligent surrounding rock quality evaluation, intelligent design, intelligent construction, and intelligent management is presented. Then, the development status of intelligent engineering technologies for tunnels constructed by drillingandblasting method is introduced. Finally, the future development prospects and trends of the intelligent engineering are forecast from the following aspects: (1) establishing intelligent algorithms and models applicable to the intelligent construction of tunnels by drillingandblasting method; (2) exploring the response law of the surrounding rock and the mechanical characteristics of the support under the conditions of the intelligent engineering; (3) developing the evaluation method for the overall stability of the surrounding rock and the integrated design method for the support system considering the time effect; (4) developing the selfsensing, selfadapting, and selfdecisionmaking multifunctional intelligent equipment; (5) forming a more safe, efficient, and economic standardized process for intelligent tunnel construction; and (6) developing a collaborative management platform with wider coverage, stronger functions, and higher intelligence level.
