Abstract:Research purposes: The purposes are to make discussion on the progresses and developments of tunnel construction technology with bored blast method.
Research methods : The demonstrations of the progresses and developments of tunnel construction technology with bored blast in China are made in the fields of the historic achievements, technical characteristics, key technologies and sustainable development.
Research conclusions: China bas made leaping technical development in tunnel construction technology with bored blast method with huge achievements, so the security of tunnel blast has been improved much in China. At present, the limiting capacity of tunnel construction with bored blast method is being challenged by the unprecedented speed and scale of tunnel construction in China, so it is necessary to develop the program software for tunnel blast design based on the computer technology for improving the management level of tunnel blast and making the further development of tunnel construction technology with bored blast method in China.
