The determination of carbon peaking strategic goal in China has put forward higher requirements for foundation pit engineering.Based on the background of a construction project in Campus on No.516,Jungong Road,University of Shanghai for Science and Technology,and based on the characteristics of sensitive campus environment and high requirements for civilized construction,this paper innovatively adopts green support technology based on prefabrication,assembly and recyclable support structure,including green technologies such as structural steel cement soil mixing wall,prestressed composite structural steel support,mixed reinforced prestressed concrete pipe pile,etc.,which reduces mud and waste discharge,and uses high-performance composite soil hardening agent made of industrial waste slag such as mine slag and steel slag to replace cement for soil reinforcement.The successful implementation of the project has certain reference significance for the green transformation of the traditional industry of underground engineering,and the realization of the goal of carbon neutrality and carbon peaking in the development of underground space.
