Abstract：With the increasing scale and difficulty of deep excavation and underground engineering construction in China, considerable progress has been made in the related techniques in both these two fields. This paper focused on the review and summary of new techniques in recent years in China in terms of high efficiency and energy saving, low environmental impact, intelligent control and ultra-deep projects in deep excavation and underground engineering. In the field of deep excavation, related theories and methods, new techniques of ultra-deep retaining walls, high-efficiency and energy-saving support techniques, low environmental impact techniques, and intelligent control techniques were summarized. In the field of tunnel engineering, simulation methods of tunnel instability and failure, ground penetrating shield technique, quasi-rectangular shield tunneling technique, and ultra-deep shield tunneling technique were summarized. In the field of prefabricated assembly technique of underground engineering, research on prefabricated underground station and construction technique of nocolumn and long-span metro station with prefabricated assembly combined with cast-in-situ arch shell were summarized. It is hoped that this will promote the in-depth development and application of these new sustainable techniques.
