The construction of urban water conveyance projects has become an important measure to solve contradictions be-tween supply and demand of water resources and improve the allocation of water resources.However,due to the constraints of un-derground pipelines such as water supply,power supply,gas,communication,surface municipal transportation,housing and other factors,in order to release the surface and shallow underground space resources,more and more urban water conveyance projects adopt deep buried forms.Based on the urban deep-buried water conveyance tunnel engineering under planning and construction in Shenzhen City,this paper analyzed the difficulties faced in the survey and design process in detail,and introduced how to sys-tematically solve the technical problems such as line and site selection,building selection,structural stability of super-deep and super-large foundation pits,maintenance and operation of deep-buried tunnels,green and intelligent construction in the com-plex survey environment of urban areas,which effectively promotes the development of survey and design technologies of deep-buried water conveyance tunnels in high-density urban area.The relevant results can provide reference for the design and con-struction of similar projects.
