The vertical concrete retaining walls are widely used in bank revetment projects, having detrimental impacts on landscape environment and ecology to varying degrees. High-strength plastic sheet pile has the ad- vantages of light weight, good durability, low maintenance cost, economical cost and quick construction. In this study, the field test has been thoroughly carried out. It designed and implemented plastic sheet pile revetment deformation monitoring test, and demonstrated the feasibility and innovation of the application of high strength plastic steel interlocking composite sheet pile ecological revetment in waterway engineering.
