In the high and steep canyon area

the embankment pile sheet retaining wall as a widespread use of retaining structure has convenient construction

low cost and beautiful appearance.But because of the complexity of retaining wall structure and high steep slope retaining difficulty

the stress characteristics of the structure is still not completely clear.According to the similarity ratio of 1∶25we established a simple model.Through indoor model test

we simulated and studied under different conditions the sheet pile wall stress state and displacement values.We studied the stress changes with test procedure.According to the test results the high and steep slope deformation and failure mechanism were analyzed.
