Abstract In order to solve the problems of low mechanization level, high labor intensity and slow construction
progress in tunnelling by conventional drilling and blasting method, taking Feieshan tunnel on Yibin-Yiliang expressway as the engineering background, the detailed analysis is carried out from the aspects of construction organization scheme, mechanized equipment operation matching method, construction process standardization management, etc., and the machinery matching technology and process standardization control scheme are put forward,which are suitable for tunnelling by drilling and blasting method. The actual construction effects show that, compared with the conventional drilling and blasting method, using the machinery matching technology it can greatly improve the construction progress, reduce the production cost and lower the construction risk; and by implementing process standardization control it can significantly shorten the time required for each process. In the construction of Grade Ⅳ and Grade Ⅴ surrounding rock sections of Feieshan tunnel, by means of machinery matching design and process standardization control it can save 23.85 h and 27.5 h per cycle respectively compared with the traditional construction technology, achieving good social and economic benefits, and realizing the rapid and safe construction of Feieshan tunnel.
