Abstract: With the increasing economic development, increasing urban populations require more and comprehensive municipal facilities. In turn, the investment into the infrastructure construction facilitates the innovative construction methods in the slope and deep excavation supporting area. As the important aspect of the urban developments, the traditional methods used in the slope and excavation supporting have the disadvantage of low efficient and have a very high potential of improvement potential. The new prefabricated supporting structure has advantages of fast construction, easy installation, the less manpower, reliable structure and short construction duration but its application is still limited due to the less popularity and lack of design theory. This paper presents the state of the practice of using the prefabricated supporting structure.
