| Abstract: | The core concept of tunnel drilling and blasting method is protecting surrounding rock, outer beauty and inner substance, valuing environment, and dynamic construction. It doesn＇t strictly rest with the designed project, but chooses appropriate construction methods and techniques according to on-site environmental condition, geologic condition, section size, form of framework, time limit of the project. Excavating by step cut method is the most essential and flexible method. construction |
