Abstract:

The tunnel construction management level should be improved and refined management should be carried out so as to guarantee safe, qualified and rapid construction of tunnel. The refined management of tunnel includes design, construction and operation; and the construction management is the key. The tunnel construction management includes safety (risk) management, technology (construction and quality) management and environment management. In this paper, the problems of tunnel safety management, technology management and environment and their countermeasures are analyzed. 1) It is pointed out that the essence of safety management is risk management. There are many relative guidances and standards for risk management in China; but still some problems exist in application. The aim of risk management is to turn unacceptable risk into acceptable risk; and in order to realize it, the refined management level should be improved. The risk prediction is the key to risk management. The geological prediction, tunnel face investigation and deformation monitoring are the most important items to risk management. 2) The managements of excavation technology, supporting technology and lining technology are the key to technology management. The technology management in China still needs to be improved. The managements of arch feet ahead tunnel face, that of tunnel face and that behind tunnel face are the keys to excavation management. The aim of supporting management is to control potential settlement. The connection of lining and invert arch, construction time of lining and control of primary disadvantages are the keys to lining management. 3) A case study of primary disadvantages of concrete lining is made. The items of management and check card of lining construction in Japan are introduced so as to reaffirm the importance of management. 4) The refined technology is the key to refined management. The author reaffirms the importance of refined technology.
