Abstract: Since the early 70 s,soil nailing wall has been widely used in foundation excavations project,but the depth,the diversity of soil layer and the difference of soil factors such as restriction,the cost of soil nailing wall control research,there is still no beyond geographical restrictions,still stay in the primary stage.In this paper,combined with the actual case of Wanda,1—2 layers of basement of common soil nail wall support in the form of classification,so as to quickly find supporting cost per linear meter,eventually achieve the goal of soil nail wall supporting cost control.
