Application of SMW retaining wall in deep foundation pits of urban roads

The SMW method is that the H-beam steel is inserted into a cement-soil pile, and by combining the loads that the H-beam steel bears with the anti-seepage function of cement-soil in a perfect way, a kind of retaining structure that is of load bearing and anti-seepage the same time is thus formed. The main points of design and the relevant method of SMW in foundation pits of urban roads are introduced. The concrete application of SMW method in foundation pits of urban roads is discussed. The application of SMW method has certain reference significance in the design and construction of similar foundation pit.
