| Abstract: | CMW method was first successfully applied in supporting engineering of tunneling foundation pit in urban express in Nanjing. Compared with bored grouting pile, steel sheet pile, diaphragm wall; soil-nailing wall and SMW method, it has the advantages of light pollution, low cost, rapid construction speed and good quality. The paper introduced the CMW method on its technical process, equipment selection, construction method, safety management and appliction effect. |
