Abstract:

In view of the situation and problems existing in the construction of urban utility tunnels, the concept of green construction of utility tunnel, i.e. improving the utilization of resource, saving the resources and energy, reducing pollution, protecting the environment and realizing sustainable development of project construction by scientific management and technical progress during planning, design and construction of utility tunnel, is proposed. And then the effective measures for green construction of the urban utility tunnel are discussed based on green planning, green design and green operation; 6 green construction technologies, i.e. intensive design technology, crosssection design technology, prefabricated assembly technology, waterproof construction technology and foundation pit supporting technology, are summarized based on green construction concept. Finally, the development trend of the green construction of the utility tunnel is prospected.

Key words: utility tunnel, green construction, green planning, green design, green operation, prefabricated assembly technology
